Low oil pressure problems....
 

Hey, i've been having some problems with my 302 i rebuilt awhile ago. This has been happening mostly after im done doing some racing. The weird thing is that I shift at 6k out of first and second, (3 speed transmission) and the oil pressure stays up all through the gears, but then when i put in the clutch and jump on the brakes the oil pressure drops to under 10. What im thinking is that I need a windage tray or baffle, what do you guys think? The good news is that I beat my brothers camaro, plus a friends cobalt (didnt expect much from the cobalt one ovbiously) Oh, and by the way sometimes my engine just dies after i put in the cluth after my "run" and i can build my oil pressure back up from below 10 if i rev it up a bit, though difficult when trying to stay on the brakes! Thanks for any info guys.

Do you have a high volume oil pump? If so, it can pump most of your oil up top with those 6000 RPM runs and leave a low level in the pan. With the hard braking that might uncover the pick up mometarily and lead to the low pressure reading. Just a thought.

I have a stock oil pump, when i was rebuilding it i was told not to go that route. Thats what i was thinking too, what can i do to fix that? A baffled oil pan? Oh, and now I have also beat a older rx-7. It did pretty well through my first gear, then when i hit second i was gone. So what do others do to keep the oil pressure up when spinning it high?

You might check that your new gaskets are not partialy blocking your oil drain back from the heads, but I would think that your on the right track with the baffel idea.You might also consider adding another quart of oil in the pan, you won't have any windage problems.

I'm still thinking a windage tray and a crank scraper might keep the oil down in the sump better and should give you a few hp as well. The ones I use are made by Canton and seem to work fairly well as far as I can tell. Most manufacturors claim 15 hp, but who really knows.

alrighty, sounds good thanks guys.

here's what it sounds like to me.

when u hit the brakes, all the oil rushes forward. a lot of the older cars didn't have a plate in the oil pan to keep the oil from going forward, like the newer cars. The oil pickup for the pump is in the rear of the oil pan.
