Question about 1990 Mitsubishi Galant
Do i got to change the hole head if a few valves are bent cheers
If you are doing this job yourself, check your pistons. Valve interference can cause small "eyebrow" contact marks on the piston tops. If these have any sharp marks where material was "pushed" by a valve, you need to use light sandpaper toi remove them, otherwise they can glow as cylinder temperature increased while running and can give you a pre-ignition problem when the job is finished.
If only a few valves appear to be bent, you should have all of them checked...even one thousandth of an inch bend can and will cause the valve to leak and burn. Any bent valves should also have the guides checked for damage. Don't forget to replace stem seals as long as you have the head apart...most become brittle with use and need changing. If you have a good machineist, he will know what to do!
good luck with your car!!
