Hello everyone,

I have a 79 F-250 4x4 with a 400 in it. When I was driving it last, the engine started making a clicking noise (it sounds like the lifters, perhaps) but I kept driving it as I wasn't at a good place to stop. As I was driving, the noise got steadily louder until the truck started sounding like a diesel -- only louder! A little later the oil pressure started dropping. It was at the middle of the normal range then dropped to a quarter and held steady, then dropped to the bottom end of the normal range and held steady until I stopped the truck. After it had cooled a while, the engine sounded like it had at first -- just the mild lifter noise.

The engine had a hard time recently when the radiator and water pump went out within a few months of each each other and it dumped the coolant both times. One of the times it started boiling before I could get it parked. Both times it got pretty hot. I've been told that it is most likely the main bearings or it could just be a plugged lifter, but I wanted to get some more ideas as I would like to get this fixed as cheaply as possible.

I appreciate any advice you can give me.

Thanks!

It could be something minor, I guess, but to me it sounds pretty terminal.

The diesel sound is prob from low or no oil pressure, what has caused this condition is anyones guess.

IMO, doesnt sound cheap
