cylinder head question
- Thread starter Stang67

Can you beg or borrow a "bore scope"? This is like a little self lighted eye on a stick, which may be fed into the spark plug recess. Turn the motor to 180° opposite TDC first.
It'll help you look for damage to the cylinder walls or piston crown. Should neither appear to be at fault, suspect a damaged or stuck valve.

8) with zero compression in one cylinder there are only a few possibilities that pop up;
1: you have a hole in the piston
2: you have a burnt valve, usually the exhaust valve, that will look like it has a chunk bitten out of it.
3: you have a window in the cylinder wall.
4: your compression gauge went bad at the wrong time.
in any case the cylinder head has to come off.

the valves may be adjusted so ones not closing at the rebuild.
