Turbo 2v first passes at the dragstrip ends in disaster

[@BOSS-jf7on]

My guess is, head gasket seal was lost. I didn't see you retorque the heads after initial warmup. This used to be a thing in the 70's when using copper head gaskets. Pull'um and see!

[@timmyrland]

Boost pressure probably lifting your head just enough to dump coolant

[@ronnorman7862]

Boostedmt good call

[@299tactical6]

This was my guess. Most definitely would also compression test and see if two cylinders on the same bank may share low compression, due to the bridge in the head gasket between cylinders possibly being compromised.

[@luciankristov6436]

Compression test it. And see what cylinder is the suspect before you rip it apart. Sometimes you won't see things visually and you'll be pissing in the wind. Also a trick I've used is to take the compression hose off the gauge and get an adapter to an air chuck. Fill the cylinder with air and leave the rad cap off. If it bubbles then you know what to do. Fill each cylinder

[@CarlosMontalvoGhigliotty]

Andrew, double check the torque on the studs, I have the same ARP 2k studs, when I torque mines everything was good, then a knowledgeable person (machine shop) told me to loose them and torque them again. Also while you are putting pressure thru the radiator try to turn the engine manually! Maybe the head gasket is seal with no boost but when boost gets in the chamber the cylinder pressure is far more than 20 psi.

[@PureCountryof91]

Ooh yeah. 10:1 is 10x atmosphere.. Soo..

[@joepatenaude3957]

Turn the motor over with the pressure tester on with a rachet or breaker bar to cycle the pistons to check for cracked sleeve

[@DesertRatRacer]

Like you were saying the 20 psi on the overflow probably doesn't recreate the problem due to heat or actual cylinder pressure. Like some other comments a leak down test is where its at. If you don't have a leak down tool. You can also use a compression tester line hooked to an air source instead of the gauge. Then pump air into each cylinder while on tdc until you see or hear where the air is escaping. Maybe start at 60 psi, lock the engine, or ramp up the air from low as the air can move the piston in a perfectly sealed cylinder. Then you can narrow down the problem when you discover the leak. Also according to the max performance 4.6 book they don't recommend cometic mls gaskets for boosted applications only NA. Then standard MLS up to 20+ psi, and copper gasket with stainless lock wire / groove for over 25 psi. Also for street cars silicone rtv around oil / water passages... Applied to both sides of the gasket sparingly. For drag race only permatex high tack on the gaskets and crc block sealer to the cooling system.

[@hermanwatson1051]

Bummer Andrew! But keep your head up brother you’ll get it.

[@TrojanHorse1959]

Is it possible that the head gaskets are only leaking when under boost?

[@mr.roush6709]

Man that sucks I hate that for you!!! I think its head gasket I had a 2V I built with the Teksid block and didn't leak off cold but when warm it did and oil looked just like yours!! I had just about same setup Mahle pistons, Manley rods and Kellogg crank! Youll get it figured out... BTW love the channel and that thing is going to be a beast

[@knight96ish]

That thing is nasty man, don’t let this get you down. You’re gonna figure it out any second now and you’ll be running even better than before. Keep at it! 🤙🏻

[@AsaKnox]

it can lift the head then after it cools down it will re seal and not show the leak during a pressure test . pull the heads and look at the gaskets. what cometic gasket are you running (MLS, MLX? )

Agree 100% Especially considering how quickly he caught it. Most people don't notice until more damage is done.

Aluminum block expands when really hot ? Possibly need a special head gasket Factory design for aluminum on aluminum action

[@mugivermusclemachines5744]

What happened to 7's? went right to 5's..SWEET!! i think your leaking is happening when hot/running. Small crack somewhere? Did you have your block and heads Mag tested? Or Flouresant dye checked? (Aluminum cannot be mag tested). maybe change head gaskets, torque and re torque several times after warm up?? IDK. Let us know what you find out!! Thanks for the awesome vids!!!

[@Boosted04GT]

Damn that sucks to see that happen. I hope you get it fixed and back running asap. Have you tried to do a compression test?

[@turbocsabi]

Crap, bro! ! I'm sorry this happened but look at the bright side. You did your job correctly and even caught it before it locked up! Prolly it just me but never trusted aluminum blocks under boost 😟

[@MikeSmith-mp7lf]

What 2-step are you using in the mustang? And If I'm not mistaken isn't that track 605 feet? 5.94 is still a respectable run, and when you get the bugs out and right tune in the car you're going to have a monster. I run in the pro 5.0 class at my track with a GMC Syclone that's built fairly well. Unfortunately the truck I own was t-boned so the frame and cab are actually from a 89 s-10. But the truck started life as syclone number 2571and I bought it at copart for a huge amount of $400. Already had the donor truck. Swapped the drivetrain and interior "as much as possible" and spent the other $11,000 a good running syclone is worth on upgrades. When you get her right I would love to get them together for a couple of passes.

[@danielhulsebus6782]

Just a question I never had the cometic MLS head gaskets some of the other gaskets used to require a couple heat cycles and then re torque the head studs

[@TFlan-hc1py]

Turbo water cooled? Possible crack in the turbo water jacket that only opens when the turbo is hot? I've seen that before so may be something to check but I'm guessing you lifted the heads.

[@andrewlavender08]

T. Flan no water through the turbo just oil

[@helomech74]

Head Gasket. Boost is causing the head to lift, shift or whatever. Need boost pressure to push the coolant into the cylinder. Could also be a a machining issue with the new sleeves. Were your sleeves wet or dry type? Did any of the spark plugs have coolant on them? Do a compression check to see what kind of readings you're getting. Start narrowing it down.

[@codyhayes1651]

Does it have a oil cooler ? Also I would try running it up to temperature and then pressure testing (after you let it cool down enough to remove the cap)

[@joepatenaude3957]

I would double check your heads make sure after break in the head gasket didn't set down some also check the plugs when you did your leak down did you pull all the plugs out? Could have had the cylinder full of air and pushed the water through the rest of cooling system like it's was air bound

[@lpssamanthayt8361]

One of those sleeves or leaking when the motor is under boost in hot

[@tomkjr1]

Rotten luck bro. I hope the engine is OK. You really need to strip down the engine to check everything for damage(fingers crossed). I was amazed at how MEAN the engine sounded at the track!

[@electrochubb]

I'm sorry for the misfortune Andy, may I suggest using copper spray on the head gaskets next time.? i apply two coats letting then dry, then one final coat & assemble while still tacky. Good Luck Andy.

[@takeastandorbeenslavedby-left]

I just watched a video that swears by the copper spray on copper gaskets. It was on the original Bigfoot truck. Check it out

[@MrDavidelliottjr]

Gonna have to look for some type of ring etc to fit around the chamber to help the head gasket seal when your wot and higher boost. Or a better head gasket.

[@atx1183]

I had the same problem with my pro charged 2V. You burned a hole in the head gasket. Once you pull the heads you should find it. It's not gonna leak until it's hot with a little cylinder pressure to help open the hole. Bad luck man.

[@ClaytonYatescarenthusiast]

I've been there so many times and my turbo 2v only made about 700. I rebuilt it 6 times and cost me well over 20k. Got it running and dumped it for 9200 buck and my life has greatly improved. I have a stockish 2016 Camaro SS that I road race and auto x and every time I start to do a built motor I remember the long painful road. Sorry to see this happen. Your situation is probably different than mine cause your attitude is still good.

[@fanoflakespeed9460]

Could it be leaking water at the intake cross over. Possible crack in the block. You can check for cracks using carburator cleaner. The crack will evaporate last.

[@iamSelfSufficient]

Sounds like you lifted the head. Change the head gaskets out.

[@akautosport]

I'm also going to guess that the head gasket area is the culprit. A lot more pressure in the cylinders than the 16-20psi from the cooling system. You can probably rule out the freeze plugs after that pressure test. I'm not an expert but I've done a few motor rebuilds and that's all I can think of. Hope it helps. PS: Not sure how your setup is now with the oil filter relocation but I remember the oil coolers can fail and mix coolant with out. If you have coolant line in that area check it over. Best of luck.

[@fordtechlife]

Bummer bro it was running so good i got no idea what could be leaking only when its hot or maybe only under turbo pressure to but you definitely need to tear into it and see what you can find hope its just a gasket issue ill be waiting to see 🔴🇺🇸🔧👍

[@ronaldbrewer4370]

Damn man that sucks ! You was hitting some solid licks for sure ! I would guess head lift during boost enough to puke some coolant into oil. We will be waiting and watching to see. Best of luck brother

[@stealthtrees96]

I had a head gasket that would leak compression into the coolant system when it got warm. Let it cool and it would run fine. Took a while to figure out cuz I didn't want to pull the heads. Just pull em, gasket and studs are cheaper than a rebuild

I've been there boss. I know you're tearing it down to nothing because of the H20, but you're not gonna find anything wrong. Had almost exact setup, same thing happened after I thought it was good. The dude from across the pond is right IMO. About those heads warping. Changed to a iron Cobra block, MHS stage 3 pi heads with MLS Cometic head gaskets....no leaks at 28 psi. Anything is possible though. You gotta pay to play in this game. Good luck.

[@icecubes_for_the_boiling_frogs]

The engine in the trucks is identical to the mustang except for cams and intake

[@JeffScrambler]

Has to be lifting the head under boost. I agree to do a leak down test but if only under boost will be a tuff one to find. Hopefully head gasket will point you in the right direction..

[@JeffScrambler]

And keep your head up and realize what mph/times your getting to.. impressive stay positive

[@wastedwagesmercuryman6018]

There would have to be a lot of pressure to pop out a freeze plug! With cosmetic Gaskets i usually run the engine dry to get some heat in the block/heads, loosen up the head studs in reverse order and retighten in order! Ive had them lift before and since preheating block dry haven't had a failure since with over 20 psi of boost on 13:1 compression!

[@Max-me9xq]

It really does sound like a head gasket when it's on boost and or warmed up. I had the same issue but it was in a 2v

[@ivanlaney2336]

Try that 340hv or the 360hv Melling pump next time if it needs one. I busted my #1 sleeve with some N2O on my 4.6 3V. Its down now.

[@nuttynut54]

I'm pretty sure it has the 360hv already in the block .. hopefully it's not one of the sleeves. That stang sounds awesome hope he finds the problem..

[@durtled]

The air in the system compresses easier than the water. Could cause the leak not to be present because its not receiving the required pressure. Just a thought. The leak might also be from oil pressure pushing past the head gasket. Seems probable. Keep up the good work.

[@AcidicGamers2]

Heard a bunch of horror stories about cometic gaskets in different cars. Wouldn’t be surprised if that’s why.

[@robertelmo7736]

I feel your pain...pulled the stock motor out of my 91' Coupe I've owned since new and put in a stroker 393...been a nightmare ever since the day after Christmas.

Can't figure out what it is the motor is getting ready to come out I guess. I'm much better mechanically now though lol... I think the head gaskets are lifting under boost.

[@beeant460]

I would do a leakdown test on all the cylinders, and also i had a issue with my old LS it would only lift the cylinder under load when i had 2 kits on,we checked in the pits i had rad cap off and put it on the transbrake and shot water out the radiator 10' high.

[@opy_savage514]

[@wyndnra1n]

Andrew, you need to get the engine to temp after doing a cold torque on the head studs. Then you need to re torque again ESPECIALLY after having a larger than stock bore. Check the modularfords online forum for correct head stud torquing procedures and specs. I am in the process of building a 4.6 4v and it was stressed to me that the head stud torque process needs to be taken very seriously if you want to seal these larger bore modulars or any high boost modular in general. Seeing as you have both of those things going against you, I would check that first! Possibly sleeves too but I doubt it.

Check the torque on your studs, I know you cleaned the threads when you assembled it but you could’ve pulled the threads on one of them. Or you have a crack somewhere.

[@TheMrREVOlutionary]

That's a tough one as there's so many changes this year... Cometic MLS gaskets are tough but not invincible. I've seen them blow quite often and don't start leaking until the engine is hot and the cylinder pressure exceeds that of the coolant. That is my first guess. Second since you had the block machined and sleeved I would do a leak down test real quick before you remove the heads. That may pinpoint the problematic area or areas. I'd verify that when the block was sleeved the the water jacket was not cut into or damaged in any way. I've personally seen a few 4 cylinder Honda motors the machine shop got carried away with and they leaked coolant under high pressure/temps. Either stress fractures or just plain machined too far causing weak spots and even blatant holes straight down into the pan.

[@jcfish847]

Pushing coolant under boost possibly!

[@finnroen2334]

The combination stock length ARP studs and 3 layer MLS head gaskets have give most Cosworth owners loads of problems here in Scandinavia. When the engine heats up and grows, nothing but the heads themselves gives way. Then one loses clamping force and the head gasket starts leaking. One other thing. Boost rules so I never understood why high compression ratio should be used in a turbocharged engine. The rapid pressure rise and pressure curve in the combustion camber becomes brutal and liftes the head(s) and destroys parts. Check out so called "Soft heads" for boosted engines. A 80 mm BW turbocharger pushes 50 psi easily, so high compression ratio is not neccessary to get horsepower even if the fuel can handle it. IMO.

[@andrewlavender08]

Finn Roen the static Compression Ratio is 11.5:1 which seems high for a boosted engine but my cams are very aggressive and have a lot of overlap that bleeds off compression. My dynamic compression ratio is 9.9:1

[@finnroen2334]

@@andrewlavender08 WOW, I think that is a lot for a engine with only 4 head studs around each cylinder. Remember Gen 1 SBC has five bolts around each cylinder and traditionally this has always been an advantage compared to Ford 302 and 351 engines when boosting them. The LSX engines got 6 bolts around each cylinder to handle the stress. I also think that the TF heads with squish areas need more ignition retard than the quenchless heads you ran before. images.ecosia.org/PSgvyH0WX3pv5ApQ9qPB1LNDeaw=/0x390/smart/http%3A%2F%2Fst.hotrod.com%2Fuploads%2Fsites%2F21%2F2010%2F06%2Fhrdp_1006_09_o-trick_head_combustion_chamber-next_to_fords_stock_one.jpg I believe one of the reasons low budget LS engines works so well is the rather open style combustion chamber shape.
