Hey everyone, so I have been running my S50B30 at 7500 rpms for a while now with a fully built head. Last weekend after a pass on the runway and one small drift, it developed as nasty tick driving through the parking lot. It had good oil pressure at idle but wouldn't build pressure like it should.
I welded the oil pump nut but three oil the bolts holding the guts into the pump looked like this:
And subsequently, my rod bearings look like this:
That is by far the worst of the lower bearing shells. Most have pitting which surprised me. I haven't pulled the tops yet but the crank looks good and I wasn't able to pick up any iron out of the oil I drained.
So the question is, is it safe throw new bearings in and button it back up? If so, how do I figure out which bearings I need? I can only measure the crank journals and not the rods.
