The motor blew today. I had the car out last on Sunday. Was running about 18 psi on sunoco 100 octane and it was running great. Today it was decent out so I took the car out and washed it. I decided to drive it to the gym. I got on the highway, and just cruised. I gave it a little gas, and thought I felt a slight hesistation. I thought my plugs might have fowled out again. I had the radio playing softly but didn't hear any abnormal noises. Then I went to pass another car and just lost power. I pulled off the highway, and the car didn't even want to idle. I had to keep giving it gas too keep it from dying. I was barley able to limp it about a mile home, making alot of smoke in the process. I pulled out the plugs on each rotor one at a time and cranked it with the egi relay out. Rear rotor made 3 strong wooshes. The front rotor just sounds like it is flooded. Doesn't seam to have any compression. There was also alot of oil in the intake tract. When I opened the throttles plates with my hand alot of oil came out. I fear that the turbo was damaged as well. What I don't understand is what went wrong. The car was warmed up, at abound 80-82 degrees C (doesn't get much warmer in this weather unless I drive really hard) I was on the low boost setting. The peak hold on the power fc read about .65, which is like 9 psi I believe. Intake air temps were in the mid teens Celcius. I still had 1/2 a tank of sunoco 100 octane. The only weird thing I noticed was a very faint buzzing sound comming from somewhere under the intake manifold when I had the car off but the key in after it blew. I'm confused, because I didn't do anything wrong. If it blew under high boost than that would be one thing, but what the heck? Maybe a fuel injector got stuck? Peak hold duty cycle on the pfc was 50%. Any ideas? I'm going to try and have the motor warrantied by KDR. Its less than 8 months old.

Didn't do a compression test with a guage, but the front rotor seams to have none at all. With the spark plugs pulled it just sounds like its flooded. The rear rotor makes uniform strong wooshes. Its definately blown.

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.
