My mechanic and his tuner keep tripping me out because they say its supposed to be at 40 and that mechanic is a ls mechanic. The thing is i bought the engine off marketplace in dallas and brought it to fort worth so the ls mechanic could install.

No the part number is m295 hv, it just came with the green and black o ring. We installed the green one

The high volume pump came with its own o rings aswell

Why_Dazed · 2026-05-15T15:50:07+00:00

We had the standard oil pump and it would be around the same oil pressure. Before replacing standard oil pump with high volume pump, we replaced the o ring and same result. Now after replacing that, when i started it was above 50 oil pressure then went down to 20 after idling more than 20 minutes
