Tap Tap Tap??
Tap Tap Tap?? I have NO idea where its coming from. Bottom end or top...
The engine has 100K on it (short block)
I replaced the timing chain,oil pump,cam,push rods, (lifters from a 50K mile car)
I get a lil piston slap on a cold start up, but then I get this tap tap tap noise.
It is noticeable at idle,but with some RPM's it seems to quiet down. (could be due to the open y-pipe)
I am showing 60psi w/ 15w40 Castrol Tection diesel oil.
Would a bad lifter or bearing get quieter with more engine speed?
I just really can't tell where its coming from..I guess I need to break out the pvc pipe
