Remove the valve cover and inspect the valve clearances. A valve which is bent will be stuck in the open position or will have an excessively
larger clearance.
Perform a compression check or a cylinder leak down check. Cylinders with bent valves will have very low compression (<50.0 psi) and will not
hold pressure.
If valve damage is detected the cylinder head will have to be removed and the damaged valves replaced. Also inspect top of the pistons for
damage.
