Problem checking p-v clearance with our lifters! (long)

[nmcgrawj]

I did it the way Nate mentioned. He was wrong about one thing though (sorry Nate!).



This is correct except for the TDC comment. The distance will actually be closest a few degrees before (on the exhaust valve since the piston is chasing the valve as its closing) or after it (on the intake valve since the intake valve is chasing the pistons as it goes down) TDC (around 15* if memory serves me correctly). Its been a while so if I'm wrong on this you can yell at me Nate! Its best to check it at MULTIPLE degrees as the closest PTV clearance will NOT be at TDC, but rather a few degrees before or after it.

You're right Paul , i think i misworded myself. I didnt mean that it would be closest at TDC. I forget the exact "pattern" of the intake and exhaust valves but i did probably take like 20 readings. Once u get the hang of it, its super easy and doesnt take ANY time at all.

Yeah. That much I did know It looks like summit has the oil pump primers. I'll order one of those since they are still pretty cheap.
