Stupid questions: 1-Where is the oil sending unit? I think it needs a good wack- it seems to be pegged, but not all of the time. I feel sure the oil pump is working fine, as it has not blown up yet...it has done this before, then gone to normal. What causes this? And what is the fix?
The oil sender unit is near the oil filter. But that wont be on the blink. It must be your oil gauge. Maybe give the dash a few whacks, that will fix it.
