Hey,
I've a '92 Crown Vic with a 4.6 that has this constant tapping noise. It seems to be coming from the top end and two of my more mechanicly inclined friends agree. Since it's on the top end I don't think it's a rod so I would say it was a lifter the way it sounds but since a OHC engine like this doesn't apparently have lifters what could it be and how would I go about fixing it.
Just a side note it drives just fine with no hesitation or anything irregular and the oil pressure is fine. Thanks for your time.
