I have a 93 lincoln continental with a 3.8 engine.The oil pressurs will show 4 bars and for no reason drop to 1 and stay there for a while then go back to 4 bars.The car has a new factory rebuilt engine new oil pressure sender and we have installed 3 instrument cluster,still the situation remaines.Is there something between the sender and the indicator? Does anyone have any ideas,my mechanic is at a loss. Thanks to all Val

Ford has a situation with grounding. sometimes a ground wire will be left off or not making a good conection when an engine is replaced or serviced.
I would sugest checking all the ground wires and conections on the block and also verify the oil pressure is alright with a mechanical gauge tied in along with the electric gauge.
another possability is the oil pressure relief is sticking and the mech. gauge test should show this if both gauges check the same.

With as many miles as a 'ninety 4 might probable have on it , i might wager that lots of your oil is staying up interior the rocker bays on suitable of the heads. The drain-returned holes interior the heads are in all probability filling or limited by sludge so as that the oil won't be able to get returned off to the oil pump as quickly because it used to. P.S. that's undesirable for the pump! :-)=

Did the engine come with the timing cover? That's where the oil pump is at. You may have a bad oil pump, or something blocking the pick-up screen.
