2002 F150 tapping
OKay guys I have a 2002 f150 that is tapping bad. Do any of you know of a fix or is it time to R/R the motor?
I have also noticed the rps like to jump between 850 and 1000 constantly and at times the oil gauge will bottom out for 1-2 seconds
2002 F150 Reg cab, long box
286xxx miles
4.2 L V6
5-speed transmission
NO fault codes other than O2 sensors but they were removed when the exhaust was chopped off by the previous owner

sounds like either a valve hitting a piston, broken timing chain guide, or even could be the flex plate loose. Had a similar problem years ago on a dodge dakota where the flex plate was loose and made a loud noise. Do you have an engine stethoscope? I would try to get/rent one maybe from auto zone. what part of the engine is the noise coming from.

I would pull the valve covers and look for anything broken ie; cam followers, dropped valve, timing chain loose. Its definitely an internal engine problem
