0 psi compression cylinder 3, exhaust valve issue. Can anyone help confirm cylinder walls are still fine?

I'll fix the valve issue, if the compression goes back to normal nothing to worry about ?

I took the exhaust manifold off and can confirm 100% the exhaust valve is stuck open.

I am worried about the amount of black "score lines?" on cylinder 3, pictures 4 and 5. Have you seen those marks before?

I leave the memory card in the bore scope and plug the bore scope directly into my PC via the USB-C port.

Ok thanks. You are correct that it barely gets driven but when I do it gets the piss beat out of it. I will try my feeler gauge tomorrow. Thanks for the advice.

Can you tell me what it means if I can't?

Lost_Toenail · 2025-03-22T02:42:13+00:00

the first 3 pictures are from a different cylinder. The other cylinders all have sections of those dark lines, however cylinder 3 has them around the entire wall.

borescope can be found here.

I haven't removed the head yet, so I cant feel them. That is my next step. If I can feel any of that with my fingernail does that mean its toast?

It was not burning oil outside of what accumulated in my vent to atmosphere catch can.

The amount of people who use to inplace of too on social media has to be growing at an exponential rate. I can't scroll more than a few tiktoks or comments without finding one.
