think I got a burnt valve
hello everyone,
Haven't posted lately been busy. My question is what are some of the symptons for having a burnt valve and how commonly does it happen.

A burnt valve can usually be found as a "dead" hole. Low exhaust temperature at that port on the manifold when shot with a temperature gun. Can also show up as an abnormal noise coming from intake or exhaust, or as "wet stacking" from raw fuel being thrown into the exhaust. Either way, its a bad thing. Not sure if anybody makes tooling for running a compression check, but if there is, you can run a compression check on the suspect cylinder, if its low, squirt a SMALL amount of oil in it and re-check. If it comes up, its usually rings, if it doesn't then its usually a burnt valve.
