no oil pressure

[Martin Dixon]

have a 2002 3lt challanger has lost oil pressure when the motor get worm but unable to find any reason why. the motor has been fully striped and inspected,has any one had a similar problem or can some light be thrown on this:

How do you know it's losing pressure, Challengers don't have a oil pressure gauge like Pajero's do unless it is an o/seas model. If you have an aftermarket gauge on it, well then maybe it's dodgy. What does the motor run like. Blowing smoke etc. Really need some more info.

oil pump clearances wrong after re build
oil pick up fallen off or not put on
wrong oil used (visc too low)
wrong oil filter

Oil pickup blocked by sludge?
