I have a 2000 Town and Country, 3.8 engine. When the engine is cold there is a tap, sounds like from the top, it only does this when the motor is cold, once is war there is no noise. What is causing this?

low oil or lifters not having oil up top its basically a lifter not being pumped up.

Did i say anything about an oil pump??
AN oil pump does not get batter as it warms up

U have a lifter issue or an oil filter not allowing oil to stay at the top of the engine

how would a oil filter get better as the motor warms up

They don't. It has to do with the fact that alot of cheap aftermarket oil filters have an ineffective anti drain valve or don't have one at all. This allows oil to drain out of the filter and the top end of the engine back to the sump. If you are using mopar filters or a good quality aftermarket filter then this usually does not happen.
