Karl, First thing you need to do is check the oil pressure with a mechanical gage. You can't rely on the dash one to give you a completely accurate reading. If it checks out OK change the sending unit, they are prone to leakage and inaccurate readings.The oil pump can be changed without dropping the pan, the screen can not. What manual says you can remove the screen from the side of the block? It's impossible, as the oil pump pickup and screen is threaded into the block inside the pan. Dropping the pan on a car with rams also requires removing the front exhaust system, as the balance tube runs right under the pan. Low oil pressure after warm up is generally a sign of loose bearing clearances. 300ly, Don ----- Original Message ----- From: Karl Peterson <longrammopar@xxxx> To: <Chrysler300@xxxxxxxxxxxxxxx> Sent: Monday, May 06, 2002 1:46 AM Subject: [Chrysler300] Oil pump removal > My service manual says I can remove the oil pump and screen from the side of > the motor and NOT have to remove the pan?
