OIL PAN

[redliner]

Just to let everyone know! Thanks to all who took the time to answer my questions about losing oilpressure on my sbc as I would increase rpm. I had a Stefs oil pan on my motor and when I reached about 3000 rpm the oil press. would start to drop. It turns out the oil pan was not doing its job as it not only leaked like a sieve but had zero oil control! I called Stefs and talked to Joe,he told me to try dif. oil level when I called the next day and the next he would NOT take my call or return my calls! Maybe I should take my 10lb. beater to that pan then return it to him! I bought a Moroso pan and my oil pressure is very stable on acceleration AND when I lift at the end of the 1/4 mile pass! The Moroso pan has a very detailed windage tray,kickouts on both sides also a horizontal baffle at the back of the sump.The bolt holes all lined up perfect and I am very happy with it except for one thing....I used a Felpro one piece gasket and in the middle of the front of the pan directly center,there is a large gap I had to fill with silicon...has anyone else seen this? I know there are thick and thin gaskets for the old Chevies but I think there is only 1 thickness on the Felpro one piece gasket. I do not like using silicone to this extent! Again Thanks to all who took the time to help! R~R

what pan where you using? what was the motor?

Recently in the last couple years felpro has come out with two gaskets of this style.
They are to be used with the correctly coresponding timing cover. While the early timing cover was to be used with the thin front seal the later cover to be used with the thicker seal. In the oil pan and replacement T/cover industry there has been issues with mixing the wrong cover with the wrong pan.
In other words if you used a pan that was to be used with the thin seal on the early cover and use a cover that is to have the thicker seal there will be gaps.
Most times when ordering pans and covers they ask what year of block. This determines the gasket to be used and they ship the part/parts based on that detail.

Currently felpro has a gasket for the pre 77 pan/cover with the thin seal and a gasket for the later with the thicker seal

Stock Chevy block (010) with a generic aluminun timing cover from Comp proucts and a Moroso pan part # 21017 If Felpro makes a 1 piece gasket with a thicker front seal maybe that what I need.....

The gasket seems pretty thick in the front similiar to the thick ones I remember from years ago.There is a 3/16s gap dead center of the radius in the front of the pan.Do you have a part number for the gasket you think might work? At this point I don't care if it's a 1 piece or not just so it seals up without using a half a tube of silicone....I like the one piece for many reasons but.....Thanks! R~R

I use 375-1880 with that pan and had no sealing issues, do you have the part number gasket did you use?

Thanks! I threw the box away but maybe I can find the part number by going back to auto zone and checking.What timing cover are ya using?

redliner what does your engine turn in RPMs, is it strctly a drag motor? What Car model are you using, Camaro, Nova, etc? Just curoius as to why you are using a racing oil pan, fill me in.

I have the Cloyes timing cover, If my memory serves me correctly, autozone only carries a gasket with a thin front seal. I had to order it from a parts house.

Yes mine is a drag motor only, its in a 74 chevy nova. I turn my 406 about 7100.

Good luck

#1 thanks for the update!!! #2 don't be afraid of the dreaded silicon. You should be good to go!!!!

The pan gasket I would use is a Felpro# OS-34510T Fits left and right dipstick blocks 79-84

Hi,I drive this pumpgas car ALOT on the street!The car is an ex D/G 42 Studebaker coupe with a 39 Ford truck dropped axle,4-link 58 Olds rear/ 4:88 gear,383sbc with Chad Spiere heads,Bullet solid roller .271/.280@.050 581 lift,110 lsa installed @104.5, dynoed at 545 h.p. before I switched from AFR 195 Eliminator to chads heads which I have not dynoed since,Liberty faceplated TKO 600 with .64-1 overdrive.With my 14-32s it trapps only 6000 and with the AFR heads it went a best of 11.16@120.98 with a big bog as I had to much base pressure in the slipper clutch and not enough gear. I have some 5:38s going in soon that should make it trapp around 7200.I currently shift between 6500 and 7000 as all I have done is some testing with it. I think once I get the clutch and fuel,timing etc optimised it should be in the 10.70s or so with this pumpgas hotrod...

On factory stuff, it's the pans where the front seal thickness comes into play. Over 2 1/4 inches use the the thick seal under that use the thin. When using after market pans and covers in combination all bets are off..... just have to figure out what works.

I didn't realise Felpro made the 2 diff. thickness gaskets in the one piece design.I am gonna invetigate further...

redliner sounds like a nice machine, awesome package. If i am you i would get a factory Z-28 oil pan wold holds 5 quarts of oil and they come with a windage tray. These pans are excellent pieces and never under estimate factory parts. Why spend all this extra money on a racing pan, you dont need it for your RPM usage. I have seen factory stock eliminator Z-28 spin 7- 8000 RPMs plus with these factory pans. Think about it, these dont leak and get it done.
