I Blew the Motor in my Z06 Project Car

The last time I had my "GT3-Killer" Z06 out at the track, I heard a funny noise from its mighty LS7. I should have investigated, but when an opportunity came up to let Ben Collins, AKA Top Gear's THE STIG test drive the car, I decided it was worth the risk...

[@chrismunos7741]

I am in awe! The Stig, Ferarri, solo Ferarri run?!?!? Awesomeness!!!!

[@askanracing]

Very well made video! Ben Collins seems like such a legend, a true sport in that moment :)

[@JoshVanVeld]

Well said. Having made car videos for a couple years, Ben is a hero, not just for his driving, but for having been a big part of the most successful and influential car show of all time. So it’s difficult to describe what a treat it was to have him participate in one of my videos. He’s so good at what he does. A real inspiration.

[@DesertRacer515]

Same thing happened to me with my 2007 Z06 following a track day... Broke a piston land and ended up with micro cracks in the sleeve. I wish I had a more competent shop repair the car. They recommended a TSP427 to replace the LS7. They told me that people do not re-sleeve LS7 blocks (which is not true)... They convinced me to go with the TSP block. It runs fine, revs slower than the LS7 due to heavier rotating assembly (pistons/rods), but it killed the value of the car even though it can hold twice the power of the original block. The LS7, although legendary, is also kind of fragile. I always thought they were indestructible (after valve guide replacement) until I owned one.

[@JoshVanVeld]

Dang man that’s a sad story!

[@farmall_cub_in_columbia3642]

For the LS7 block, a company out in Oceanside CA, Racing Engine Development (R.E.D.) can make you a replacement LS7 block from an LS3 block. Actually his LS3 to LS7 block conversions are better than the OEM LS7 block. He can also re-sleeve your block if the block damage is minor. Next, get a forged bottom end kit, steel crank, forged rods and forged pistons. This is your chance to get away from the titanium rods which can gall at the bearing cheeks and can also be a cause of engine/rod bearing failure. Also changes to an upgraded piston from the eutectic pistons to forged. Next are the cylinder heads and valves. I figure you have a least one cylinder head completely survive and hopefully the other can be welded(?). In any case, go to Katech and get their head package for the LS7. This solves all the issues with the LS7 valves. Fixes the bad OEM valve job ( main issue with breaking valves), replaces the DLC coated titanium intake valves with Moly coated valve stems. Much better for the application as the DLC coating is rough and wears out the guides. Replaces the powered iron guides with hardened bronze. Slightly better heat transfer which helps the exhaust valve and bronze machines very well so the guide to stem clearance can be held very tight and keep the valve dead centered in the port bowl and valve seat. Your 2007 had the first generation exhaust valve which were updated in late 2008 or 2009. Katech will likely recommend to replace those exhaust valves with the updated valves. For the track, as you know, the dry sump lubrication system as designed doesn't fully solve the G loading issues. The dry sump update to the 2009 12 quart sump may be good or an aftermarket dry sump. What is also needed though is a better windage tray. Improved has a good kit that is a crank scraper and windage tray, their part no. : EGM-740C Configurator. They have track data on their site that shows how well this solves (improves) oil pressure from hard cornering and braking. I figure around $13,000 in parts to do the above which is a lot of money. However, this LS7 is better than the stock one which, (fixes all the fragility items) when available sold for more like $17,000+ from GM. Hope this helps. Reach out if you think I can help.

My Mazda had the same thing happen at Road America. Not enough oil at the pick up during high G cornering, starved the engine and spun a bearing after like 5 laps. Now I'm building an 07 mustang gt xD

[@joshuahailes1673]

Hey Josh, I feel you completely here as I just had a rod bearing failure a couple months ago that lost me oil pressure and the factory rods. I'm replacing the factory short block with a forged one from Dart since I'm going for stroked and higher compression n/a build and will probably go for higher power with a decent shot of the good stuff eventually, but that means I have a factory ls7 block and crank that are still good with roughly 29,000 miles (2009) on them so if you end up wanting them let me know and I can arrange shipping with the shop that currently has the car. I personally wouldn't reuse the factory pistons as they are cast and a weak point and the factory block has only proven reliable up to 800 wheel as the cylinder walls are fairly thin to support high cylinder pressure. That's a big reason why people are recommending the ls3 block to use with boost. It definitely is the cheapest of the safest options to support boost.

[@JoshVanVeld]

Hey fellow Josh, thanks for the offer! If it makes sense after I've dug into it I'll look you up. Sorry to hear about your issue but sounds like you're going to have a monster on your hands.

[@camonly849]

So sorry brother! I'm glad you took away something positive. I think that type of mindset is golden. I emailed lingenfelter for my c6z about an aftermarket motor. They have a race series motor - eliminator spec r series - which is incredible. The 427 eliminator spec r motor is about 800hp crank and is supposed to he their reliable race/drift motor. You can beat it up! This motor I was told was $30k. They also have a 454 making 820hp. I'm not sure on the price on that one. Jake rozzell has the 454 in his c5 race car and it sounds absolutely glorious. Check it out. 820hp at 8600 rpm. I know katech is insanely expensive, so lingenfelter could be an option for you. Again, I am very sorry to see this. It's never something you want. Wish you the best.

@Josh Van Veld's Racing Mind ya definitely haha. The lingenfelter eliminator motors are ls7 blueprinted. I think the katech is an LT based, but to compete hp wise... its gonna be like an additional 10-15k. Maybe I'll be lucky enough to slap one in my car!

[@cristianflores-pq9to]

I feel your pain having blown 2 LS7s, I know people say fix the valves/heads and it’s bullet proof but I’ve seen plenty of the built guys drop valves or blow that engine. I will say I ran in to a guy that opted for a built/cammed LS3, not the same but had been much more reliable for track racing. Food for thought if you continue. I know that 7k redline is heavenly but perhaps that’s the real Achilles Heel of that engine aside from Oil Starvation from the dry sump when you’re beating on it.

[@JoshVanVeld]

Wow, my new goal is to be able to say a year from now that I've only blown ONE LS7. I can't even imagine what the second one feels like. That seems to be the common theme that's emerging - the LS7 has some really alluring aspects but if you want true reliability for track work, it might not be the best starting point... I don't think this is going to be an easy decision.

[@cristianflores-pq9to]

@@JoshVanVeld the Z06 is supposed to be a purpose built track beast but the heart of it can only take so much. Grand sports seem to be the happy medium which I am leaning towards for my next Corvette. One thing I will say is no matter the cost, do what’s gonna make you happy because although I had blown 2 engines, I put 35k hard miles on the car between 11 seconds quarter miles, and a lot of track days. I looked for excuses to drive that car and loved every mile of it. But older wiser me will not do that again haha. Also, make sure to get an extended warranty, 5 years motor power train. That saved my wallet, only had to pay $5k for replacing to oil system out of pocket. The second blown engine was fully covered by the manufacturer warranty on the new engine. Towed straight to the dealer from Leguna Seca and did not void that warranty haha. Good luck with whatever you decide! You have a lot of fans excited for the future regardless 👍🏼

[@RAM_C5]

Heads really should have been addressed before anything else.

[@cxavier68]

I am really sorry to hear this. I have been following for a while now since you got the C6 Z06, and I remember following your journey with the C5 as well. In 2021 I also bought a 2007 yellow Z06 with similar intentions as yourself. I had a C5 Z06 long ago, and I sold it because I knew the LS engines had oil pressure issues on track. I experienced a low oil pressure warning on a left had sweeper at Roebling Road even after I overfilled it and I didn't want to take a chance. So jumped into the C6 partly because I knew it had a dry sump, but I knew it had its limits. After all my research and with this new purchase, engine reliability was important to me. I replaced the original 21k mile heads with machined heads. I did this because I knew others experienced dropped valves. The early hollow stem exhaust valves had thin walls and manufacturing tolerances could make them a potential failing point. The intake titanium valves had a coating that could fail, and the titanium could wear the valve guides. I was lucky and found a pair of ported and fixed heads with ti moly intake valves and lightweight stainless steel exhaust valves along with aftermarket guides. Comparing the original and new heads, there was definitely play in the original valve guides. I checked the new heads after 8k miles of street driving, and they still feel solid. I didn't measure them, and its not scientific, but it was enough for me to be confident that they are fine for now. Long left sweepers like at AMP also concerned me. You may have seen the thread on the corvette forum, but someone (Dreamin) captured data on the loss of oil pressure (20psi) at Thunderhill with a similar high speed left sweeper in their 07 Z06. They solved it by installing a larger oil tank. I went in the same direction but I installed a 2009 oil tank and added an Aviad oil tank insert. There is a lot of information out there and some of it conflicting, but I would recommend keeping your next engine as stock as possible with fixes for reliability. I added long tubes and a cold air, and the car is more than fast enough. I added an MSD manifold and NW throttle body, but it ended up being problematic and removed them. I've been tempted to replace the stock cam, but these cars really don't need it for the track and it just takes away from the reliability. If you see what others are doing to make their LS7s more reliable for track usage, they are reducing power and not trying to make them monsters. I don't know if this will help, but I thought I would share. Don't give up, and this doesn't have to cost 20k. I'd buy a low mileage replacement engine, and use it as an opportunity to update the valvetrain and install a bigger oil tank with better oil control. There are plenty of LS7s that have lived long lives on track.

[@slick408]

What was so bad about the msd intake manifold? I'm thinking about running it with stock TB

[@JoshVanVeld]

Wow, I was wondering if anybody'd seen my C5Z thread. I did read that oil starvation post on the forum and thought it made a lot of sense. I am definitely all about prioritizing reliability over power and I was planning on making those mods, I had just been putting them off. Everybody thinks it won't happen to them until it does 😅

As an LS7 owner I have been contemplating with its future lately myself too. My car is the opposite of yours- just a bone stock 8K mile garage queen. Fixed the heads 2 months after getting it.

Its a shame because i love the way these cars look, love the LS7 for what it stands for......but its really making me never want to buy a GM ever again.

Corvettes are amazing value for money but they are built to a price point and sometimes it shows. That said - these cars are getting older and a leaking oil pan gasket is annoying but not the end of the world. I've found that the fastest way to fall out of love with a car is to let issues fester. Get it fixed asap and you'll feel a lot better 🙂

[@ssoffshore5111]

It's probably leaking from the front or rear main seal. These cars are now 15+ years old, so seal failures is to be expected from any older car as they dry out and harden over time, especially one that isn't regularly used and just sits in a garage! This is universal and unrelated to being a GM product.

[@SHODUUP]

@@ssoffshore5111 it is leaking from the most forward facing (under crank pulley) oil pan bolts. After a ten min idle- oil is forming on the heads of the bolts. I’m going to try the cheap fix first. Removing them and putting some sort of sealer on them and putting them back in.

That was b4 I saw your channel ❤ and have been following the clips religiously:) An aftermarket shifter will help to, from what I have seen, a lot less effort and more positive shifts. The excel spreadsheet shows up massive similarities, in dimensions , weight bias, width of track, etc, a pattern starts to emerge between the top say ten super cars. ( Not talking Hypercars) The C6 with a bit of lightening and extra HP will keep pace and actually turn same and better lap times with 700 hp at crank , some proper downforce and later, the at least two way Adjustable coil overs.

As one person mentioned keep LS7 and if necessary bid on a wrecked crashed car to get replacement LS7 engine, if going super low cost route and do the standard Mods for reliability and just an extra 100hp taking you to 600hp at crank. Have a hunch though, if you do the due diligence and be patient collating truth versus fiction:) From the genuine engine builders, with honest dynos! You may find another 200 hp, (700hp at crank) Without spending ridiculous amounts on that last 100hp. You will know before hand by adding up the parts cost and labour to assemble. Seems 600hp at crank was around $5k to $10k included exhaust & intake improvements. Valve guide upgrades, think that covered shaft mounted roller rockers to. Personally as you love the hands on experience. Ensure the final engine builder you choose, let's you actually go in and be a part of the engine assembly process ❤. They will still need to be financially compensated by $$ or by exposure on channel, signage on car etc. Yet again you will be promoting them, their skills + knowing you " built, assembled your own high hp kick asse LS7. As mentioned, LME Late Model Engines , Texas Speed & Thomson may be ok with that. To assemble an engine is not massively labour intensive. The machining and collating all the correct parts to be at the shop takes some time. Yet if you allowed a couple of days at an engine shop, three probably tops. You could have your GT3 powerplant all built and run in initially on a dyno. Be a great video clip you being coached thru the engine assembly by LME or Texas Speed. I loved re building Chev V8s at an engine shop in my late teens. Especially when you are coached by awesome blokes who know their Art:) You will love the sense of accomplishment and " ownership" Teaches one to have mechanical sympathy for the engine and machine.

Same for hp...no point 700hp, if it is only in a tiny rev range or rev band at the very top of your rev range....like early S2000 Honda! With 9000rpm redline and almost ZERO Torque :( Versus their early Integra Type R which had about 8500rpm redline, sacrificing only 500rpm at top end, yet had great useful torque thru much of the rev range. Good to work out the typical rev range you operate in for most of the time, averaged across the majority of your road racing courses. Also noting approximate drop in revs when changing up, from the most commonly used gears. That will assist you select the right camshaft:)

Sorry about the blown motor, sir. Best of luck with the next steps.

[@Gearhead9001]

Hey Josh, I just recently found your channel and have been watching several of your videos. Absolutely amazing content, keep it up! I am a fellow C6Z owner, and one that also had a valve drop at that. I am incredibly sorry to hear about your LS7 failure, and I hope you can get her running again soon. My '06 dropped it's #6 exhaust valve at 19,922 miles on the dot on my brother's birthday in August 2022. I went with the LS7 route once again and got myself a crate motor from Scoggin Dickey for $14.7k. I had some trouble along the way getting it together, but that's irrelevant right now. I ended up going with American Heritage Performance fixed and ported heads and a BTR stage 3 cam with supporting mods. My car has ran flawlessly 3 months into having it fixed, although the car was down for 7 months total. It's your car and you're welcome to do as you please, but I'd really recommend to keep your faith in the LS7 and go for a crate motor and just get some reputable fixed heads. Oddly enough, I wouldn't recommend a huge cam. If you want your car to perform well on AutoX and track days, I have found the cam becomes a handful and slightly less usable than the LS7s already decent power output, and streetability takes some getting used to. That being said, I really have a blast with my car being cammed and I need to get it on the track sometime soon. Being in Arkansas makes it difficult being that there's only one circuit within 5 hours of where I live. Good luck to you and whatever you decide! I tried to keep this concise, but I know my way around the LS7 pretty well despite me being in the youngest C6 owner age group, so feel free to reach out to me on Instagram @lunarz06! I'm definitely a new subscriber and will be a returning one.

@@JoshVanVeld it will need to have the sleeves removed bored then resleeved/honed/decked etc, it is expensive but then you end up with a solid high compression high revving n/a v8 with DI. You can of course skip this and just stroke the stock lt1 block but you will only get to 416ci and it will be oversquare instead of undersquare like the ls7(aka it wont rev out) the folks over at btr can also help with cam and heads selection.

That stinks. Horsepower Research in TX also makes nice LS7 upgrade packages.

[@louiC6Z]

There are a lot of good engine builders so you shouldn't have a hard time getting that done, I personally went with LME in Texas, they built Feras's motor who holds the production lap record for almost every big track in the states. One thing I would 100% recommend is going with aftermarket heads. The aftermarket addresses alot of the issues that the stock casting has and are a lot more reliable. Check tolerances every other season (depending on how much you track) and do the necessary oiling upgrades, pan baffle/trap door, bigger tank from lingenfelter, etc. Log your runs and pay attention to oil pressures under braking and corners, that is the best way to know your setup is working right. Another recommendation that I was told from one of the biggest LS shops in the states, in LS7 motors the piston velocity and speed is so immense which puts huge stress on the valve train, invest as much as you can on the valve train and the motor will last a lift time, make sure to do link bar lifters and shaft mounted rockers for valvetrain stability. Good luck!

[@JoshVanVeld]

Hey buddy, I live right there in and Gwinnett county close to you. I have a Z06 as well.

I had just dusted my buddy in his C7Z and was feeling great and then heard a slight change in sound (pretty sure it was one of the dual valve springs breaking) and the next lap I got the smoke show. I had a great experience getting an all new built LS7 with RHS block from Chad Golen at Golen Engines in NH. He offers a fully built engine to just about whatever spec you want with a 1 year warranty and didn't up charge for the RHS block. Good luck!

The thing is, build for the horsepower you want,you’ll regret it if you don’t. Don’t do if I ,woulda,shoulda,coulda. If your going to continue to track the car my two cents worth is spend money on the valve train. That way you have a buffer if you over rev on a downshift or something like that. Get a center counter weight crankshaft,helps with high rpm stability in rotating assembly. Don’t go to high on the compression so you can still get pump gas. My new engine I just got is assembled that way and it will turn 7500 no problemo. Of course figure out the dry sump, maybe a better oil cooler. That’s just my opinion,I don’t know nothin,good luck.

I don’t have much to add other than you should try a lightweight clutch/flywheel. I have one in my c6z and it’s brutal for street driving, but in a road course application it would be terrific. It revs incredibly quickly. In your case I’d yank the engine out through the top, it’s actually not that difficult. Put in a new rotating assembly, get the heads worked over by AHP, add a small cam and good lifters, good oil pump, some 1-7/8 headers, lightweight clutch, new balancer. And slap it all back in.

Damn. Sorry about your car man. I’ve been following this build as a first time vette owner and enthusiast (13 C6 Grand Sport). I chose the GS simply because of the LS7 issues as I daily drive the car, but if it were a track/fun only car I probably would’ve gone Z06 anyway. The valve guide issue is 100% real and even cars with “heads fixed” still drop them sometimes. Even if you had addressed it there was still a chance of this happening with track use. Still, it remains a phenomenal platform and I hope you get her fixed up. Curious to see what you go with for a replacement engine. Can’t go wrong with LS3 but then it wouldn’t really be a Z06 anymore. Bulletproofing a LS7 gets expensive but probably worth it long term if you’re planning on keeping it. Best of luck!

I have tracked my 08 Z06 a number of times in the 11 years I have owned it, not as much as you it seems. Before I did, I changed to the larger oil tank from the later C6 Z06's. Not sure if this has prevented issues for me, I think oil starvation issues can be track dependent to some extent, but GM seemed to see the need to improve the oil tank after a few years production, so I did that upgrade as well.

That upgraded tank (the Lingenfelter version) was on my to-do list. I think AMP has characteristics that probably expose that issue if you're going fast enough.

Not to mention the significant weight added right over the front hurts handling and braking, less than idea for a track car. If you're looking to make 525-600 rwhp, that can easily be done NA with a H/C/I LS7 with better handling and braking dynamics.

from a reliability standpoint i'd be considering a crate LS3 plus a cam, make similar power to stock at a decent price point without overwhelming yourself with a ton of horsepower while you continue to learn on the track. that would be under 10k usd easily, with plenty of headroom for other unexpected costs or extra hop-ups if you really want some more power (head work can get SBE LS3s into the 500+ whp range easily). might not be as "special" as an LS7 but it'd be expensive to replicate in a reliable manner. also wouldnt consider forced induction for a track car, superchargers put out too much heat to comfortably manage and turbos arent viable in the limited space under the hood (plus more components to possibly fail)

Some thoughts having a fair amount of experience with these cars. The oiling system needs to be addressed, especially for that track. At a minimum upgrade to the 09+ tank. There are several other aftermarket upgrades worth considering as well. For track use, I'm also a big fan of adding an oil accumulator (plus you can eliminate cold start OP issues with them). I thought I saw oil under the car, if so, it likely has a new window in the block and it's scrap. A fairly bulletproof solution is to switch over to the LS3. They are stout, cheaper, and can still make decent power. Personally, even though I have one in my SL-C, I'm not a big fan of going this direction in a C6Z. It decreases the value of the car, both financially and emotionally. And IMO, having had the LS7 in the car, it's hard to go backwards. The LS3 lacks that specialness of the larger LS7 with it's better flowing heads, more cubes, and higher rpm. Yes, you can mod them to make similar power, but no matter what, they still lack the better flowing heads and usually the higher rpm. But this is a sound option if you just want increased reliability. Whatever you do, you absolutely want to stick to an aluminum block for weight reasons. I would stick with the LS7 and use this opportunity to add mods and make improvements. I'd look for a donor engine and go through it and do the basic upgrades. Inspect the bottom end and address as needed. If budget allows, aftermarket forged rods and pistons. I would absolutely go with a good set of "fixed" CNC ported heads (preferably aftermarket IMO), install a slightly larger cam ("stage 2") to keep it awake closer to redline, do headers and possibly an MSD intake. I know some folks say stick with the stock cam for reliability, but installing a slightly larger cam really allows these engines to pull a lot more on the upper end, it's totally worth it IMO. The extra NA power will be quite noticeable and welcomed on the street and track (watch out GT3's!) Yes, you'll still need to keep an eye out for the valve guide wear from time to time, but it's not like you're going to rack up high milage on this car and to me this is worth the effort as the performance results and retained value of the car will be superior. Once you experience a C6Z with H/C/I done, you'd be really hard pressed to leave it stock, lol! Even with a mild cam, those mods will add around 100rwhp and be amazing on the street and track. Ditch the cats if you're okay with the smell, otherwise get a set of high-flow lower cell count cats. Speed Engineering offers a great header and exhaust system for these cars and it's fairly cheap. No cats, but they can be retrofitted. Lot's of different options out there, but I guess it all comes down to what your wallet will support, what your expectations are, etc. But again, what really makes these cars special IMO is the LS7, and I'd be extremely hard pressed to give it up! I'd stick with it, make it better, and mitigate as many of the known weaknesses as possible, but that's just me! Obviously you can go with another beefier aluminum block, but the cost will certainly escalate. BTW, absolutely don't forget to upgrade the clutch (and install a bleeder) while it's all apart! It might be worthwhile to rebuild the torque tube as well while it's out of the car.

The oil looks like it came out of the intake. Not sure what to make of that. I feel the same way about the LS3. Probably a wise choice, but not really in keeping with what made the car special in the first place. Thanks for the write-up, great food for thought.

@@JoshVanVeld I would suggest bringing the car home (I'm assuming you already have), pulling the valve covers for inspection, checking behind the TB, and sticking a bore scope into the spark plug holes. You can get a cheap bore scope for use with your cell phone for little money and they are handy to have in general. I suspect the bore scope alone with tell you what direction you're headed... It would be nice to see if you have oil pressure, but I wouldn't turn the engine over until you have a better idea of where/what the failure was. This could be a rocker arm bearing, valve spring, broken valve, etc. If you don't have oil dripping from a new window in the block, and there's no spare parts behind the TB blade, it's quite possible some of the big ticket items are salvageable. Pulling the valve covers and inspecting with the bore scope should give you some valuable info for your next steps.

Fabulous write up. Thank you. I own an LS3 base Vette and I have driven a couple LS7s and I have to say the LS7 is just special even if just for the sound. My next will be a Z06 for sure.

[@Vander_berg]

I'm on my 3rd LS7 in my 2007 Z06😅

[@Vander_berg]

Lost 1 to factory exhaust valve drop. Lost the next one to a stainless steel intake valve (too heavy)... but the 3rd is built proper including oiling mods to run on slicks.

[@JoshVanVeld]

Dude. NOOOO! 2 failures? That's awful. Glad to hear 3rd time is the charm.

[@Vander_berg]

It was early days when exhaust valves starting dropping, GM was ignoring the problem and the aftermarket thought stainless steel was the answer. 2 motors in 1 year😅

[@JoshVanVeld]

@@Vander_berg Goodness. Were they covered under warranty?

[@Vander_berg]

Negative... no warranty. GM pretty much banked on no failures during the warranty period.

[@MrEddie152]

Sorry Sr I was truly wondered if heads had been done

[@JoshVanVeld]

Haha no need to be sorry - I knew it was something I should have dealt with right away when I bought the car but I kept telling myself, “I’ll just do this one other project first.” Still need to confirm that it was a dropped valve and not something else.
