Q: valves rattling bad

asked by on

had blown head gasket blue devil it i think i used to much now no oil coming out of push rod what can i do

This could be caused by a variety of things such as excessive valve clearance or a push rod lifter that is not working correctly. This can require an extensive amount of time and diagnostic work. I would recommend having an expert from YourMechanic come out to your home to diagnose and repair the rattling issue for you.
