1999 F EXPL XLS 4.0 has chatter

Asked by Jan 30, 2007 at 07:07 PM about the 1999 Ford Explorer

Question type: Maintenance & Repair

Chattering while engine is running. Someone told me they had same problem and it was engine timing chain tensioner pulley. The Chk ENG lite has also been on even after all 3 O2 sensors where replaced. Anyone have any advice. Clattering in TX.

Hi Cody ... depending on the mileage on your explorer since the belt has been replaced (i.e. if it's over 60K since) your friend has probably hit it on the head. You want to confirm or debunk that theory before the belt proves him right however because it's a much bigger fix after the belt lets go. Have a mechanic take a listen to it, especially if the "chatter" is internal. Good luck!

My 99 EXP XLS has 4.0 OHV not SOHC. I am told SOHC is the engine with problems with tensioners and faulty cassettes. Does the OHV 4.0 have any similar kits available b/c it has the exact same chatter?

I believe the belt tensioner issue is ONLY the OHC engine and not the OHV engine, although the timing belt could be bad on either. Could be valve train noise in any case in the older 4.0; best to let a mechanic look at it before jumping into any teardowns.
