Re: Catastrophic engine failure, suspect pre-ignition (Pics to follow)
Well, I decided, what the hell, I'll take a quick peek and see what I can see. I found copious amounts of oil in the intake plenum and in all cylinders. My throttle body passageways were overflowing with oil and there was a small amount of oil in the y-pipe. No oil pre-y-pipe or in the turbo piping. Noted a large puddle underneath the car (ie. 5 feet in diameter). Made a note to self, that I need to drain the oil pan next and then I pulled the plugs.
Plugs 1,2,4,5,6 all looked good except for the fact they were dripping in oil. Plug number 3 was a different story. The pic is pretty much self explanatory, but I'll describe it anyway: both positive & negative electrodes are bent and contorted and the insulator is completely destroyed. Looks like its been hit hard.
