Re: Make slowboy not so slow

Scheides and I did some diagnostics over at his place Sunday afternoon. I originally went to change to my summer tires (forgot my jack in Iowa) and do a boost leak test, but we ended up doing a compression test as well.

The first obvious problem was the sludge in the intake pipe, coming from the compressor housing. It looks like an oil/coolant mix, which could explain why there is sometimes oil or coolant out the exhaust after I get on it. See pic below.

We then did a boost leak test and found two major leaks. Out the valve cover and out the dipstick. Not a little air coming out, a lot. It probably took 30 seconds to fall from 25psi to nothing. So then we did a compression test and got 150, 151, 145, 145, so that looks pretty good. At the time we didn't know what was going on, so we called it a day.

Then Scheides PMs me last night and says it could be the turbo causing all this. If the seals are really bad on the turbo then the air could get into the center section and into the oil pan, then out the dipstick and valve cover. Seems logical enough to me, since I know a lot of oil/coolant is getting into the compressor housing. As soon as my Red gets here I'll send in the turbo to PTE to have them look at it. 234 hp FTL.
