Hey guys,

My oil pressure is dropping under hard braking. It will drop as the car is coming to a stop, stay at Zero( check gauges light comes on for a sec.) then jumps back up to normal once the car is settled and completely still. My car is a 96 WS6 6spd with 60k miles. It's running fine, oil pressure is fine under all conditions EXCEPT under hard braking. I checked the oil( mobil 1 5w30) and it looks fine. I change it every 3000 miles.

Soooo, I'm gonna change the oil and check the filter for contaminants. Any ideas what could be wrong?
I'm praying it's not a bearing

Any input is appreciated

Thanks,
Rob S.

 

Could be the oil pump pickup fell into the pan. When braking the oil would move forward letting the pump suck air. Drain the oil and rap on the bottom of the pan with a rubber or plastic hammer, to listen for the pickup to jump up and down. Or run a coat hanger thru the oil drain hole to see if you can feel anything in the pan.

 

I agree, a loss in pressure when braking and then slow increase means the pickup is off or you have some serious low oil by about 3 quarts!!! you said your low oil light comes on?? Then you are low on oil!!!

 

Thanks for the quick reply.

It's not low on oil so it must be the pickup.

Do I just drop the pan and reattach the pickup?

thanks,

You should remove the oil pump and have the pickup tack welded to it, to prevent it from happening again. The factory just press fits it in.

 

please let me know what you find out about this because i
have had the same problem for some time. But a friend of mine
has a 94 z28 and his does the same thing.

 

I have a spare working pump and pickup if anyone needs it.
