To Hi-HP MPI CARS! ~ PSA

he is saying to go with an actual aftermarket 3rd party turbo that’s retrofitted to mount to the factory head, Like the apr efr kit or an iroz xona kit... on that subject, iroz just posted this with thier ims780 kit, haha.

Damn that turbo is spooling fast. It’s touching 400whp at 4500. My 6266 Evo 8 was crossing the 400whp mark at 5200rpm. Super impressed

I'm done posting updates due to people being assholes but lets just say boroscope led this to a resolution.

Im a little metal short and stout. Here is my handle here is my spout.



But what was it?

 

[mk7_bk]

I don't know what this means, but it cant be good. Oil should be on the cylinder walls to lube but not on the head like that. Plus cracking and flakes im guessing its toast

Edit: this is what google tells me, I don't little as many know

Wait, I’ve seen this Xfiles episode. That black shit is bad news. Sorry Twist.

ok scully

Tip of an injector? Piece of a valve? Cant be that with good compression.

 

[mk7_bk]

part of the turbo in the cold side?

 

[Diggs24]

or piece of piston from under the oil pool

Its carbon/DI gook. most have that that is not oil. For oil to make it onto top of piston like that compression would have to be damn near zero.
and thats not the problem. The flaking isn't the problem. The Det isn't the problem. The compression isn't the problem. Look closer boys you'll see it.

First person to call out the number of pic that is true problem gets a hell of a deal on what is about to be a hell of a part out

 

[mk7_bk]

my money is on picture 4, where there is that gold/green looking stuff, thats the problem

 

[Diggs24]

I see the piece in photo 3.

Something without a doubt went through motor. . Typical heat damage near valves indicating highway abuse. Minor det damage on top near hot side which doesn't concern us. Top of piston appears to be cracked but we think it may be an optical illusion from using coat hanger sharp side to measure/ manually crank engine down to see pistons. Modern cheap boroscopes suckle arse. CYL 3 only one to have it and cyl 3 was not only healthiest cylinder but also the ONLY cylinder that either didn't shut down during all this or 1s knock issues (but also COULD be why it has

Driving back 20 miles with nothing but some turbo whine. Also, just because a turbo breaks hot side doesn't mean it couldn't have gotten thrown back in.
150,000rpm chunk of metal > Exhaust Stroke if timed right.
Tomorrow well crack turbo apart and see whats up. From the outside it seems just the 1 fin. Premature turbo fail would show multiple fin damage and contact marks all in the housing.

The real issue is the pitting (mk7bk . PM me once part out is up you can take your pick xD) Something able to do that to multiple cylinders and take out 1 wheel alone leaves a trace. And there's no trace. Plugs perfect. FILTER perfect. Manifold perfect. Injectors perfect. Valves in theory ARE perfect (enough to seal anyway). DV is intact. All piping clean as a whistle. But since multiple cylinders had the "pitting reflection" we're going to assume it is not caused by drivetrain failure and rather foreign debris in intake stream. The only explanation that is not related to un seen intake side damage is bits of IC. This is where I could use some advice guessing as to what could've done that/ what to check Tomorrow we'll have a tiny bit more information.

Now the real question is will it drive on is20 If you take away the "modern ness" and "scaryness" and view in the context of simply a piston in a cylinder.... the bitch is more than likely fine. On is20 heat I bet this thing makes it to 100,000+ even with all this. But I could be very very wrong lol

Damn Twist I’m sorry to hear that. You really had the worst luck with this whole thing. I agree I was going to mention that something could have some dislodged in the intercooler and gone through the engine. That’s really the only other place something could have come from. I hope you figure it out!
