While doing some street tuning near where I live, a T-fitting for my turbo oil feed/oil pressure gauge cracked. The oil dummy light turned on so I drove it home (stupid move I know, but I was only a few blocks away). Sent my 68hta to Justin after finding some in and out shaft play. His findings were, "It's 100% fixable...honestly it doesn't even look like it had any oil starvation as there's no bearing transfer at all on the shaft or housing, just appears the thrust plate failed because they're not using upgraded thrust hardware on these turbos when they're built."
Installed everything back on and did a leakdown and compression test last night after driving the car around to warm it up. The photos below show my numbers along with my piston info. I rebuilt the motor (6 bolt in a 2g) less than a thousand miles ago.
What do you guys think? Do I need to pull the motor, rehone, and install new rings or is there something else going on? From what I've read those leakdown numbers are really bad, but the compression looks good. One thing to note though, when I did the compression test is it took many cranks (around 30/ea. cylinder) for the needle to finally stop at 170psi.
