JPJMustang Posted January 25 Report Share Posted January 25 Started the 3.5 the other day - starting to have a loud noise (not normal low ticking) - sounds like a rocker/lifter noise. Sound when idling Will go away when you step on the break and put in gear. But can still hear (not as loud) Tried heavier oil - but still had the sound In your opinions - ok to drive (just annoyance) - or should I pull covers and try to replace lifters? - assume hydraulic lifters - Am I correct?

DILLARD000 Posted February 25 Report Share Posted February 25 (edited) Could try an oil additive (Lucas "engine honey"), or a premium brand of oil like AmsOil (extra additives for minimizing wear.). Have a personal habit of spraying a little Carb+ThrottleCleaner down the Oil DipTube & Oil Fill, then run engine idling for 5~10 minutes, then change Oil+Filter; believe this helps clear out sludge+dirt deposits throughout the engine. Of course do make sure your oil level is in the upper range on the DipStick.. Also put an eyeball on your 2 belts; a belt or belt tensioner can tick loudly if they're getting worn.
