Losing oil pressure after run
Losing oil pressure after run At the end of a run, when I let off, I lose oil pressure breifly and it then comes back. I have tried the stock LS pan, and two different pans with all kinds of baffles and trap doors. Pickup height is correct. Adding oil does not seem to help. I have run as little as 4qts and as much as 6 qts. It has great oil pressure thoughtout the run and any other time. Has anyone run into this before? Has anyone restricted the pickup tube to control the oil flow?
Thanks!

A lot of super stock sbcs see the same thing. One friend tells me with the water-weight synthetic oil that is not so pronounced with his car. Faster drain-back maybe? I'm suprised more oil doesn't help.
Ive had alot of oil pressure problems with the stock pans.This year i went to a moroso and all my probems went away.The moroso has a rear sump that is included with the pan and it also holds 8qts not 6qts like they advertise.

Thanks guys. I have been away from my computer for a couple of days.
Our LT1 Stockers and Super Stockers do not have this issue at all.
I do not believe the Moroso pan is appoved for NHRA Stock. I would hate to run that much oil.

I had a simular issue that went away after going to a thinner oil. I know it isn't anything you haven't thought of, but I just thought I'd mention it again. Also I know Harland was having som problems with oil moving up the back of the block on one of there cars that was launching with a Trans Brake so you might just contact him also. Y2Khawk is his name on here if you don't know him. Good luck.
