Oil Pressure Dropping When Braking

[Fastbowtie]

Ok, here's my first post. I have a little problem that has just shown its ugly head tonight. I was driving my 68 Camaro and hit the brakes moderately and happen to look down at the oil pressure gauge. It read 0. Now when the car was completely stopped it return back up to 30 lbs. At first I thought it might be the pick-up but when I tested it by accelerating it went to 70 lbs at 6000 RPM. So then I tried to turn the car right and then left to see how low the pressure would go. The lowest it would go was 20 lbs now mind you this is in a circle. You can't get too much RPM in a circle. The car is a protouring car. It has a set of sticky Nitto NTO1 on all 4 corners and a Hotchkis swaybar, springs and QA1 shocks. The Brakes are Touring Classics 13 inch 4 way discs with Hydroboost. The engine is a 350 with a stock 1970 Z28 LT1 oil pan along with the windage tray and a stock Z28 Pump. Does anybody have any idea whats going on here? Thanks Guys for the help.

The oil is running forward in the pan when you brake. The pickup sucks air. when the car stops the oil comes back and everything is normal. When you turn the oil hits the side of the pan and the pickup can still get some oil.

You need a better oilpan with baffles that lets the oil stay around the pickup.

Yep, Jan is correct. Get yourself a good pan and you will be good to go.

Yea but Jan is'nt that supposed to be a Trans AM racing pan? I thought that was the one they used in 69 and 70 Trans AM Racing Circuit. I don't think they were allowed to change pans were they?

keep in mind that the "street" tires of today are far better than ANY race tire from the late 60's/early 70's, your car probably has a lot more "grip" in street trim...than those full blown race cars had.

also, if the rules mandated running a stock pan, i would assume that they probably modded it with baffles or trap doors so as to not oil starve the motor.

Ok so I hear what you guys are putting down. Now who has any suggestions of a Oil Pan for a 68 Camaro's with a small block? I was thinking about Stef's, Hamburger, or GM Performance Parts. This is mainly a street vehicle so clearance is a requirement. I will however make a trip to the drag strip or road race it too. Thanks Guys I love this form it is so awesome.

gonna have to let a f-body guy answer that question, my project has no clearance issues and a dry sump

Oil pan for an early Camaro that works well:

A CV Products #1080LTRR.

Carl Casanova has one on his Camaro and it works well on the track, check for pics on his webpage:

Thanks Blown353 but 8 quarts is a little excessive for me. I would'nt want more then 7 at the most. Boy that new LS7 is looking better all the time is'nt it (Dry sump).

more oil is good, that is a 7qt pan + 1qt in the filter. just think, my set-up takes 4.5 gallons for an oil change
