I have a 1990 auto. When I got my car it had a massive dent in the oil pan. It has good pressure under normal conditions, took 4.5 quarts when I changed it, and didn't make any clunking noises when I had my head under there so I left it alone. The other night I was beating on it and noticed after a burn out there was a red light on the dash and the pressure gauge was climbing but I didn't see how low it was. I'm thinking that the huge raccoon dent is effecting the slosh or the pickup tube. Have any of you seen low pressure on high acceleration? I looked back on some tunerpro logs but can't seem to dig up an oil pressure parameter? that sucks...
Anyway, my autocross plans are off this weekend until I replace the pan. I read thru Grumpy's forum comments on the subject, just wondering if there are any new part numbers out there. How about Moroso 21324? Of course, I want all the features of a $350 pan for about $150. How deep is the stock pan?

Reason: clarification
Your big dent has probably pushed the pan up to the pickup not allowing it to pickup oil correctly. I know of some drag racers that run 1/2 to 1 qt. over full for high rpm usage when there is alot of oil in the upper part of the engine so as to not starve pickup.

FWIW I went with a Kevko pan made in Minnesota. It is model 2001, 'stock appearing' with a scraper and baffles. Standard capacity and I also asked them to install a provision for a turbo drain back line !!! Fast service and good people and I think this is a good value.

Any pictures of the pan on the car? I'm interested in this pan but worried about the extra 1/2 inch of depth.
Is it 1/2" deeper? I didn't notice although the engine is out of the car still for total rebuild. FYI stroker crank clears also
I used Kevko 1001 pickup tube and a melling M55HV. What do you think of a remote mount dual oil filter and maybe additional cooler? My car has the oil/water heat exchanger, which is really close to the header right now. I may need to search that topic.
A 7.5" deep pan is no problem. Lowest point of the pan will be even with the K frame.
The Kevko 1091-RR (7.5") and 1092-RR (7") are $225 and $235.... The proper pick up is additional $25....You are going to be $250 into it. You will also need to remove the factory windage tray (these pans have integral full length louvered trays). You will also need to drill a 1/2" or so hole in the tray for the dipstick if you intend to use one.... However if you plan to autocross and road race seriously, a good pan like these will be money and time well spent.

Thanks for the pics and info everybody! I'm also mulling over removing the factory oil cooler since I have the system drained but my car will see little if any autocross.

The heat exchanger is also an oil heater in colder weather to get the oil up to temperature. Personally I would not be all that quick to throw it out unless a full time road race car.
