I recently bought an 87 f150 four wheel drive with a 302 and (I think) 130,000
miles. It started running low oil pressure about two weeks ago. I've changed the oil pump and just got done putting in rod and crank bearings. It helped a little but not much. Also I did put a mechanical gauge on it. Any ideas.

 

What's yer idea of low pressure? The engine is just fine if it has 15lbs pressure at idle.

 

I'm talking about zero. But the engine never makes any noise.

 

An engine with zero oil pressure is not only going to make a lot of noise, it's not going to run long either. I'd say there is an issue at the gauge.
