In similar situations I would reply "Maybe God knows why..."


In this situation, I think even God has no clue at all.....

Blown headgaskets, damaged pistons from improper afr, detonation related damage, bent rods from excessive boost, etc. etc..... i would categorize mechanical failure in the valvetrain as not directly fi related...Especially considering there is a KNOWN problem with the valvetrain in this car.

You can't fool the dealer.

How is it "very easy" ? i have all factory parts including all pulleys, header, oil pan, intake system, injectors, etc etc. also all original harware. Also, the dealer themselves do not care, it's corporate who has to be convinced.

Hey man, if that was the case, i would not be so disappointed, rod through block, full boost, boom!, but no it was a lame ass way for a motor to go.

14.5-15.1 at steady cruse, have logs under boost, nothing out of the ordinary afr under boost 12.5-12.9 is there a better way of sharing them on here than print screen?

Just FYI, it is nearly impossible to make E50-E85 knock... Like REALLY, REEEEEALLY hard...

So, even if you were cruising, might have been knocking quite a few.

Also important to note, there is a local with FA20club kit that has a metal clanking sound in one head (he says the sound was present before turbo kit, it just got worse now) and it seems it has to do with camshaft advance mechanism.

The weird part it went from running normal, no odd noises, to death, marbles in engine, in a matter of 30 seconds, this is after about 200+miles driven in the last 2 days without any noises or any sign of anything failing.

Not really. You could PM me, and I will give you my e-mail address. @jamesm would probably look at them too.

Talked to dealer, explained what had done to the car, and they agreed that it seems like a mechanical issues that has now become well documented, they've had a few cars with similar head issues already, they said revert it back to as stock as possible, the call on repairs is out of their hands but they'll try to do everything they can. i made it known that if they cannot do it under warranty then i do not want them doing anything with the car, so there's incentive for them to try to get it fixed. Also purchased an engine with 8k on it and it should be here in a week or so, just in case they can't do anything. Either way i either have a replacement engine with my stock blown motor to rebuild, or they replace it and i have a used low mileage engine to rebuild for boost. win win, except my wallet, that was a pretty big loss haha.

Those seem lean to me. But I didnt sleep at a holiday inn express last night.

There isn't a "KNOWN problem with the valvetrain in this car." There are, however, about a dozen documented (read: KNOWN) blown motors using FA20club parts and tunes.

http://www.ft86club.com/forums/showthread.php?t=15577 there is a known problem, some of the cars listed had catastrophic engine failure at less than 1k. A few people that have commented on that thread had a failure identical to what i just experienced.

Now don't get me wrong, i'm by no means defending fa20club, my dealings with them have been absolutely awful, had to file a paypal claim with them to just get my clutch, not to mention originally getting the turbo kit piece by piece over a 6 month period, when it was supposed to be a "couple weeks".

OK.

So you think there's a known valvetrain problem. And how are you reaching this conclusion?

The fixes for cam sensor-related issues are not extensive, they are (at worse) a replacement of the oil control solenoid valve or cam sprocket. Even if these items aren't working, the valvetrain still will open/close at regular intervals (but the nonfunctioning solenoid may cause an emissions issue or an engine code issue)

I asked the question because I question the way you reached this conclusion, that your engine failure issue isn't related to your FI.

Just because you're not under boost doesn't mean your engine is bulletproof from issues associated with FI. If the tune leaning out is causing the engine to fail, that's very much a FI-related issue and you won't get warranty coverage.

Edit: I know you are referencing the issue with the list of owners with CEL/cam problems, but the way you are reaching the conclusion is a bit of a stretch. Similar symptoms does not mean the same diagnosis.

The car I talked about showed no signs of knock. It only showed if logged. It behaved perfectly normal, no sounds or symptoms....
