Well I was searching around and found a little info on this so I was looking for some more considering my car keeps breaking down on me and I dont want to park it just in time for summer.



Im wondering what all should be done to a rebuilt motor with 30000kms on it to getting running like new again cuz mine has several wiring issues and seems to be hesitating , and has littttle too no oil pressure once warm (0 kg/cm2 at idle and maxs out at about 20)



My oil cooler is pretty rough lookin but it was like that when i bought the car .... i wish i knew the brackets were brokin off on both sides and the bottom of it is all dented up yet it is not leaking. could this be the cause of the low oil pressure problem?



So basically im saying my engine internalls are probobly not damaged its just the engine is really greasy and needs to be cleaned up.



It would be helpful if you guys gave me an idea of some stuff i could do to get it like new again that would be apreciated.... thanks

 

It's not unlikely that it's your oil pressure sending unit that is bad and giving you a low reading. I would verify it with a new unit or a mechanical gauge.



Make sure your engine grounds are clean and tight, check for vacuum leaks, install new plugs, and clean your injectors.



You might start with a compression check just to make sure everything is okay with the engine.
