what was your knock reading on the powerFC?
Knock reading on the PFC means nothing. Its just noise. I've heard that its common to get a hig knock reading on decceleration from all the engine and drivetrain noise.

Ihor remember when I installed the diff. at my shop? I told you your idle seemed not normal. In my opinion the engine had a sound like a hurt apex seal. I think your engine was previously hurt from prior high boost when your wastegate was giving you problems. I made that comment to Vosko, about how your idle was not normal.
I don't think it was previously hurt. Was making good power. I made 470 to the wheels at 19-20 psi a few weeks ago. As far as I remember, my idle always sounded like that.

are you going to rebuild it, or buy a reman, or???
If KDR warranties it, I will pull the motor and have them rebuild it. Otherwise I'll pull it at Steve's house when I move to Texas next month and rebuild it myself under his supervision.

I was maybe at 5000-6000 rpm when it blew. I eased into the gas to pass another car and lost power.

Ito, it seams like all three seals on the front rotor are damaged. When I crank it with the front leading plug removed it just sounds like it is flooded, no compression. The rear rotor makes uniform and strong wooshes. If it was a previously damaged seal, then wouldn't just that one seal break instead of all three?

its possible peices from the damaged seal broke the others, are they still in there? usually the 3mm seals like to "leave the building"
