Re: What happened to this turbo motor? (Outkast95LS)
looks like it ran lean maybe and/or the P/W was too tight? those bearings dont look healthy, not like any beat up bearings ive ever seen.
id be curious to know too, those pistons are awefully dirty for only 2400 miles or was that a thermal coating?

Blueprint shows .004" PW and there is no coating on the pistons.

Looks like oil was leaking into your coolant passages. Coolant or fuel in your oil which "could" have caused your bearings to wear like that. Your PW clearance is too loose IMO.

There was no coolant in the oil or oil in the coolant. The PW clearance was actually a little on the tight side for a turbo motor.

Def looks like you ran uber lean up top along with a tight piston/wall clearance like everyone else said

Re: What happened to this turbo motor? (awdgsx96)
Looks like a lean condition in conjunction with the tighter spec pw clearance. the lean condition just allowed the pistons to expand enough to scrape the cylinder walls as well as start to melt down the pistons. Also looks like oil somehow got into #4. Although generally lean will give a very light color opposed to the brown/black you see... interesting.

too tight piston to wall, too lean, or too much ignition timing. what engine management? what a/f at 14psi, what timing and what fuel at 14psi? what ems?

Oil level was fine. It was Rotella T. NGK 7 plugs. Turbogixxer(Kenny) gapped my plugs for me, i forgot what they were at.

We were tuning with crome. As far as i remember timing was very,very conservative because we were street tuning it. The a/f was in the high 10's low 11's. We couldnt get it leaner at WOT, we were going to put Neptune on the car the next day to rule out Crome as the problem, then this happened.

what do you consider conservative? was it properly synced at the distributor?

I'll have to have Turbogixxer get back to you on that.

Re: (Jared)
if u say the tune was in the 10's id say you washed out the rings...which would explain **** in the oil..causing the bearings to get that way..also the **** ontop of the pistons...

Yeah, that was my first impression when i pulled the rod caps off. Others didnt think do. Just wanted another opinion.
