Had a cylinder 4 misfire on a 200k mile LC. Swapped coils, no change, did a compression, 75psi in cylinder 4. Put a borescope in it, didn’t see anything obvious as far as burned valves go, piston looked good, bore looked good. Pulled the valve cover, nothing obvious there. Unfortunately, I lent out my leak down tester so I haven’t been able to do that yet.
The car sat for probably a year prior to this and supposedly ran great before it was parked. It does have what sounds like a lifter tick at idle, runs great above 1000 rpm. I wouldn’t think a collapsed lifter would cause this but I suppose crazier things have happened. Any guesses?
