Hey, I have a 1978 Plymouth Volare with a 225 Slant six, Not sure what I should do, It is having a problem with oil pressure, I can't afford to fix it, But at the same time it is my only car at the moment, how would I go about figuring out the price? I have Replaced the Exhaust manifold, fuel pump, brakes/lines, fuel lines, radiator hoses, and a bunch of other stuff, It does run, but has a knock due to the issue with what I believe to be the oil pump... Would appreciate any advice on possibly fixing the car or even any idea on what i should try to get from it if I decide to sell it. Any real advice would be greatly appreciated.

 

Have you changed the oil ??? the filter could be plugged ? Or take the pan off and replace the rod bearings as a temp fix

 

Do we know why it started knocking? Ran out of oil?

 

the knock could be the reason for no psi. /6 are strong engines. try a new filter and oil and drive it easy see if it goes away. if not run heavy rotella untill u save up money lol. what psi do u have btw 10-15 is still ok under normal conditions
