The cover I pulled was the passenger side cause it only takes 8 minutes to remove with everything in the car. I expected to see that the clearance between the lifters and cams was non existant even when you push down on them. But I had plenty, so I figured that wasn't the issue. I ran a compression test on cylinder 6 and it was good, 140 or something. This shocked me. I was just thinking that there is no reason why this motor should not run. So I put the plugs back in and wires on without the valvecover and tried it. SURPRISE!!! Even my wife came into the garage. I even started it a second time just to make sure I wasn't hearing stuff. The motor sounded perfectly healthy, just slightly different with no valve cover.

You can imagine how incredibly angry I was when I put the cover back on and its back to step 1. I have thought about my own theory, and have concluded that most likely oil pressure is not the problem as I remember thinking this a few months ago and trying to start the car without the oil filter attached to see if it would fire without any pressure on the lifters. It did not. And besides, behavior like this is childish and borderline stupid.

So now I sit here and wiat for intelligent thought...............Still waiting............
