http://www.dieselplace.com/forum/smileys/Big Smile.gif Just purchased a 2004 Chevy Duramax 3500 LLY and traded a 2002 Duramax 2500. My question is that the oil pressure for the new engine is 20-30 psi idling and 55-65 psi running. My old Duramax LB7 ran at 40 psi idling and 80 psi running. Is this a problem? Could the indicator be bad or are the new engines normally carrying lower oil pressures?
Well I'm not one of the techs, but those numbers reflect what mine are...
From my experience with other types of engines, I don't see a problem with those numbers. In fact, I think they're actually better especially for those of us who live in areas where it gets cold in the Winter and the oil gets thick...http://www.dieselplace.com/forum/smileys/Ermm.gif
I couldn't say if it's a problem since I figured it was normal. We'll see what the guru's say.
