[@ninaallen7849]

I'm thinking Valve float from not changing springs when they upgraded the cams that's why issue was at high rpm and also why piston eventually hit valve hard enough to cause damage I would bet more than 1 piston will have sign of pistons hitting valves old springs cam upgrade is probably what led to all this

Engine builder here: Rich dip could have been caused by weak valve springs, this is a common thing to see on stock early LS engines and Barra 6's. It would also be the likely cause of your dropped valve, it would have valve floated up in the rev range, most likely because of the new cams making it go places it hadn't before.. Always a good idea to replace valve springs with a cam change.

[@DYhondaman]

yeah, i would have to go back and double check if they did new valvetrain parts (springs, etc) when they did the cams. larger lift without a matched spring would be poor judgement. plus younger tech working on older air cooled stuff didnt give me that much confidence.

[@codywendt9693]

​@@DYhondamanthat guy seemed like he had no idea what he was doing

[@ninaallen7849]

It would also explain his Dyno graph allowing more air so the power curve was weird but the timing and spark was off because of them floating causing the air fuel to be off

[@welshjohn02]

I didn't see his build. Watching this as he said he broke it. Did he not do springs with the cam? Interesting. Wouldn't you also do valve train, guides and seats while in there? And if there was a dropped valve, did anyone measure piston to valve clearance? So many things.....Just know it's not ideal to just do cams alone

[@danielalexander8229]

the cylinder bore peice is called a "Jug" usually - think of a dirtbike/ATv engine /VW engine/Corvair engine - valve probably dropped due to excessive RPM and had valve float - if the springs in the heads weren't rated for the new cam lift or were just on the edge of compensating for the higher lift then that would do it. In these engines its not as big a deal because each jug (cylinder) is seperate - so you can pull the head, have it repaired with new valves, pull the one damaged jug and piston replace those and put it all back together. The good thing about these engines and most air cooled engines is that each bore is pretty isolated - all in all if you dont have to split the case or messed up the bottom end which unless theres bit of piston that got into the bottom end which is very unlikely its not that big of a deal

[@djdavis4713]

If the valves aren't closing correctly during compression due to float, then it could push some air back through the valve, leaving more fuel than air, causing the rich dip? So valve float could be the fuel issue, and explain the dropped valve. (I am not a porch mechanic) edit: if its floating both valves, it could also push an unburnt air fuel mixture out the exhaust, causing a rich reading out the exhaust.

[@The888Redlich]

Or a spun big end bearing allowed the piston some extra stroke & to meet the valve. That could be disastrous if there’s crank damage or swarth through the engine

[@danielalexander8229]

[@justinelliott293]

I am not an expert or even well educated, but I did learn about air cooled engines in A&P school. We learned about spring resonance frequency which at a certain rpm/frequency the spring wouldn't be able to react quick enough and the valve would float. I believe the solution was dual springs at different rates. If your valve did drop, I would look into the possibility of dual springs. Again, this was in relation to aircraft engines, but they were very similar from what I understand.

[@ninaallen7849]

Yep especially with bigger cam should always upgrade springs

[@Ninesixmike]

Factory springs are dual and sufficient for the cams installed if in good condition

[@ninaallen7849]

@@Ninesixmike I guess we will see when takes the engine apart but by the graph and what happened seems to say otherwise I would almost bet those cams have higher spring rating on the engine they come in then what was in it but we will find out eventually it explains the power band and why it hit if there floating engine is getting more air so power band moves higher but the ignition isn't working properly for that causing fuel issues then eventually hitting piston I would be interested on spring rate of each engine this factory engine and them those for upgraded cam

It was a broken valve spring and you were floating a valve at mid RPM on one cylinder. The seat pressure got so weak after redline Dino runs, it finally kissed the piston while floating. I doubt you replaced the valve springs when you installed the new cam, with the higher lift the spring was depressed more than it had been during its service life, due to general metal fatigue, it’s a role of the dice. This is a reason to replace the valve springs when you upgrade a camshaft on any engine that’s had some miles on it. Unfortunately the dice roll for you was snake eyes.

Probably valve float, I don't remember if you changed the valve springs to match the new cams but the more aggressive cams need heavier springs or the valves can float at high rpms and contact a piston, it probably just bent the valve causing it not to seal, usually if a valve drops it would have caused a lot more damage.

[@SamuelVelter]

It could've been the muffler bearings too, ya know?!

[@AlwaysSearching..]

Hilarious 🙄

[@ryandeweese363]

Thanks for all the content! Its awesome to see all the growth over the years, think i found your channel with the cream s15? Anyway, bummer about the engine, sure youll figure it out soon

[@matthewisaacs5307]

Really enjoyed your video, especially the explanation detail. My son recommended your 964 story after I told him about a problem I been chasing in my VW Beetle. I like hypothesizing before pulling but often end up finding suppm different why I do the actual pulldown. Looking forward to a confirmation of the problem

Time for a 13B swap! can't drop a valve with a rotary!

[@jerrywilcox9890]

Ya that's not going to happen.

[@Berm_Blaster]

Apex seals have entered the chat...

[@jerrywilcox9890]

Be stupid to put a junk noise smelly rotary engine.in

[@johnnygeorgopoulos4072]

Get out 🫵 (Even as a rotary fan, that's a disgusting comment lol)

[@Leonn_.]

For the ones finding it boring, here's a summary: -Spark plug was smashed. -Spark plug contact with the valve. -Valve probably dropped. -Piston very damaged. -Probably had weak&leaky valve springs. He doesn't know what to do yet... Edit: Thanks for the likes, can't wait to see this car running at it's full potential after another rebuild 😢.

[@NoAutoBoomin]

Thanks can move on until he builds or swaps lol

[@cingkole7893]

Can't drop valves with a rotary.

[@mbirdie12]

@@cingkole7893no, you can drop pants with a rotary tho😏

Genuinely one of the most interesting video’s you’ve made in years. I’m really, really bummed for you. That said I’ve genuinely never been this engaged in a video of yours since the purple R32 giveaway build series. I get that this channel has changed and that you need to be the new algorithm and marketing focussed Adam now, but this video was straight up nostalgic in the sense that we got to see the old you again. This video is one of the rare instances of the return of plain black clothes, black raybans just started with the mustache Adam, which imho was THE peak of this channel in terms of era. Just sad that the reason for the nostalgia is a car blowing up… Hope the damage is somehow managable even after watching those last few minutes about the dropped valve. Hope you can just slap on a new bore and piston and refresh the springs and retainers and call it a day.

[@vtiniall]

To be fair Adam, being honest and showing all does show that everything is not golden and always running. There are downsides to all and any builds regardless if you are experienced in that specific build, in this car the boxer engine in the Porsche. I love all the Tech information, it shows your knowledge and you learning each time. Look what is done is done, the car will be back up and running sweet in no time. The E36 is first, can't wait to see it ringing the compound. Get some rest, clear the head, sleep, eat and go at it again in time. Thanks for the video.

[@WillSatchwell]

Playing devils Advocate here, Get the guys at Tuthill in the UK to build you a 4.0L engine with the new Swindon 4V heads... 12,000 RPM and 400bhp potential might just break the internet!

[@johnnygeorgopoulos4072]

While I agree, that 911T they built is absolutely sick, I don't think it would be fitting for how he's planning on using his 964, IMO, a nice stroker from DeMan Motorsports would be a better fit (still haven't watched the video, so IDK the extent of what happened yet)

[@WillSatchwell]

@@johnnygeorgopoulos4072 while I get that logic, the 964 and air cooled Porsches are not really what Demann specialise in. Would 100% send a GT3 to them in a heartbeat mind. Would be more logical to go to Ed Pink if that was the route but sit tight, Chris Harris said on the Collecting Cars Podcast he has just done a wild video with a Tuthill 964RS with the 4V heads.

[@farooki8021]

Rotary swap incoming!?👀

[@jamesdunn3387]

It was so cool to see this car at Amelia. It is frustrating for you but this is really exciting content. Thanks for the post script as well.

[@damiansmith5294]

I'm so sorry man. I will patiently await the day that this beautiful car returns to the road.

[@maverick4177]

Lastern Subura 6 banger swap incoming 😂

[@John-bd3ts]

Made in Chin. A

[@deontepowe8229]

Adam figuring out old technology and going on rants is my favorite thing lol

[@paulknight1879]

Sorry to hear that your Porsche engine failed hope all is good soon because it is an amazing car,and I loved watching u redoing the car .

[@kidmars93swagg]

I’ve been so invested in this build, I hope he sees it through.

[@pro50joe]

Love these in depth technical videos! Sucks it’s such a costly one though.

[@bennsport]

This is a real bummer man, been enjoying the thin mint content so far!

[@finiccyfiniccy2053]

It'll be all good bro. I just crashed my 350z two days ago bruv. Lets keep it pushing and embrace how lucky we are to live in these times and get to build our favorite cars. Cheers LZ

[@jeffshappard8227]

Sorry for you, as I know this is a major bummer! Whether you have 1 car that's a DD, Weekend Warrior, Shine and Drive Princess, etc…or 100 amazing halo cars…this sucks emotionally. Keep your head up, we're here for your journey and I personally love all the detail in this video. Looking forward to future updates. Peace.

[@travisharshman480]

Great video, very informative. Even the best over think situations that end being out of our control at the end of the day and was nice seeing it filmed

[@michaelfrench1]

Hey adam, tough news to hear but i hope you still continue the build. It's a beautiful car and a beautiful colour on top of that, hopefully you find out what happened to make the rich spot

[@cjjarv]

Adam you're a gem, thanks for making this no doubt difficult but very interesting video. Please don't be disheartened; think of this as an opportunity! Imagine all the awesome upgrades you can give that beautiful engine, the learning that will entail and the work of art that'll result. If you need to justify those trick heads well your audience demands them! I really hope you get to do as much of the work yourself as possible despite your schedule. Best of luck living the dream this year mate.

[@kelleycook4753]

I wasnt really into porsche but this car is one of my favorite cars you own. its the vibe for sure. looks amazing. sucks to hear the news, i enjoyed the nerd talk. good luck.

[@ALC570]

Sucks this happened, but the educational stuff is some of your best content. Even if it doesn’t do numbers please don’t stop doing it

[@coastal_clan1651]

Honestly explained it pretty well I love cars but mostly know only basic stuff but you explained it well enough for me to understand good stuff Adam

[@geroldslade478]

I appreciate seeing the highs and lows of car builds
