Oil problems?
Heres whats going on
When the truck is cold it seems to run smooth, no weird noises, and oil pressure is at a respectable level , has plenty of power
but once warmed up it starts to tap near head #1 or #2 and oil pressure starts to flucuate and drops very low, i also lose most of the power in the engine
it was suggested that it might be a stuck lifter any suggestions?
