Good location for ext oil filter 289 fia

After only 4k? Naaah, and the thrust bearing could have come from your transmission shaft sticking in too far. And it's a myth that you have to get your oil temp up to 212 degrees to burn off moisture and contaminants. 180 to 185 is perfect -- there's loads of authoritative texts, studies, and SAE papers that confirm it.

This is one of the things I'll be checking when I get things back from the machine shop. Also, there are heavy machine marks on the thrust surfaces of the crank. Should these be more of a polished surface? I'm finding other questionable engine build techniques like using 50g balanced flywheel and harmonic balancer on a 28g crank. They drilled the bejesus out of them to get a balance or close to balance, who knows. The engine never seemed to run smoothly since I bought the car.

Maybe you could post some hi-res pics so that the experienced engine builders can see them. I do know that some tri-metal bearings can have funky coloration, which is perfectly normal, while other manufacturers might use different coatings, which make them look different but is also perfectly normal.

Can you post a photo of these "heavy machine marks"?
If the crankshaft has been reconditioned, there should not be machining finish visible on a bearing surface.

It was hard to get a photo that accurately shows the marks. It almost looks like someone went around the thrust surface with sand paper. I drag my fingernail across it and it's very apparent. It is not polished in any way.
