Valve chatter

Asked by Broncoman217 Aug 05, 2018 at 12:08 AM about the Mercury Marquis

Question type: General

I have a 2005 Mercury Grand Marquis LS. I'm
having valve chatter with the oil when I start it up
but quiets down a little bit after I start driving. I've
tried changing the oil using full synthetic and I've
also tried cleaner. Does anybody know what the
valve chatter could be as it is not going away??
