Hey everyone. I've got a problem that I think I know what's going on, but I'm not sure how to fix it.
'89 IROC 305 TPI. Stock oil pan, high volume oil pump that's less than a year old. What's happening is that when I come to a stop the oil pressure drops. If I have to come to a moderate-to-hard stop, it'll drop almost completely down to 0, then slowly come back up. Doesn't do it so bad when the engine (and oil) are cold, but gets worse as the engine warms up (thus, the oil thinning out).
My theory is that the oil is rushing forward in the pan away from the pickup and because it's a high volume pump, there's none left in the pan for it to pick up - it's all up top.
First mistake was probably to put that oil pump in there - should have kept it stock. But, it's already in there. I've heard I could add a little extra oil to help the problem. Do you all think this would be a good idea, and if so, any idea how much extra I should try? I've also read about some sort of baffolds (sp?) that can be put in the pan, but I'd rather not have to drop the pan as it involves pulling off my Y-pipe from the headers.
Thanks in advance for any opinions!
