02 timing chain TSB
Hey anyone else here with an 02 EX have a timing chain rattle on acceleration? There is a TSB on the 4.0 where they replace the chain, the sprocket and the tensioner. Also, what kind of hp gains does changing to a KN filter give you?
My 02 Explorer (4.0 w/less than 30k miles) has been making a pingy rattle on acceleration and I'm told theres a Technical Service Bulletin from Ford about it being a loose timing chain. Anyone else know about this and have any experience with the fix?
