So I've posted on this before got some replies and just kinda figured screw it I'll replace the engine with a sohc eventually.
Anyways the issue is a rattle around 2k+ rpms under light load (when in gear and barely on the throttle) sounds like loose metal like gears or something. A loud rattle. No it's not a deep knock and no it ain't valve train it's very weird sounding. The oil psi is pretty dang low 8 psi at idle with 15/40 diesel oil.
So I figured I'd have to rebuild the motor or swap a sohc in like I've wanted to. However I just had an idea, could it be the oil pump is loose (gears ground a little or something weird) and rattling since it's not tight anymore and now I have low oil pressure and that nice is because of the the oil pump being screwed.
I have no bearing material in the filter, the motor pulls 20" hg at idle so it's a strong running motor that noise just bugs the hell out of me. I just don't know what else would rattle like that, thrust plates? Idk even know what those look like anyways haha
