Oil pump failed?
Oil pump failed? If an oil pump were to fail in an ls1 engine, what would you expect to find inside of the pump? Failed as in zero oil pressure. I pulled the pump out and opened it up, looked used but nothing cracked, broken, spring was fine etc. If it wasn't the oil pump failing, where do I look next without yanking the engine out? This is in reference to this last thread of mine https://ls1tech.com/forums/generation-iii-internal-engine/452904-oil-pump-question.html
How would I be able to know if this is what happened? The piston looked like it was all the way up. Above it there was a small hole which I could see daylight through. Shouldn't extra pressure push the piston down against the spring. I don't know why there would be a hole above it. And the hole is round, doesn't look like an accident. I dunno, could the pickup have become blocked that quick and easy. And is there a way to check it without completely dropping the oil pan? Please help me
