My car was leaking antifreeze from the intake manifold gasket. My mechanic
replaced the gasket and phlemun (sp). He also replaced the PCV valve and replaced the oil pan gasket which was slowly leaking.
He flushed and filled the radiator, replaced all the oil and filter. Then the car started leaking oil bad from the crank shaft gasket so he replaced that. He pressure tested the engine and had perfect pressure, he also tested the cooling system and all was ok. Now the oil light comes on when I am at an idle or am slowing down which to me indicates low oil pressure but then what do I know. Then while driving the car it just stopped dead in the middle of the street. Now the engine makes a constant clanking noise, oil pressure goes up and down when tested depending on RPMs. Mechanic
says to get rid of the car after all of this.
Could this be A. oil pressure sensor, B. Crank shaft position sensor, C. Oil pump going out. Oil clog in some port or something??? Should I get rid of the car? Help...my mechanic can't figure it out.
