That can withstand Rotary heat offcourse? I did use the copper type from pepboys and the manufacture claim it can hold up to 700 degree. I need to know if there is better temparture sillicone gasket out there, and what some of u guy's had try. Thanks, khris

Any good RTV silicone will do- I use the grey one on my oil pan, but the copper one will do the job too.

I used the copper on this last engine. The trick to the oil pan is...MORE IS BETTER.

Before replacing the gasket on the pan, look at all the bolt holes, excessive tightening will cause bolt holes to warp and cause an uneven sealing surface. a flat edge and the round edge of a ball peen hammer can be used to get any imperfections back to normal.



A little trick to getting a good seal, clean all visable residue from the pan and block surface area, use light sand paper (180 or a higher number) and sand the entire surface, wipe down with thinner or lighter fluid and paint a light coat of spray paint to the pan. allow about an hour to let the paint dry, coat with a generous bead of Silicone gasket and spread it evenly 1/16- 1/8 thick and allow 20 minutes for the gasket to become tacky. try to leave expansion room on the oil pan for when the seal is pressed into place to keep excess silicone from squeezing into the oil pan when the bolts are tighened. oil pan bolts do NOT need excessive pressure to seal the oil pan. once the oil returns to the pan there is no pressure on it, so worring about holding back engine oil pressure is not an issue. Once the bolts are tight wipe off any excess gasket that has squeezed out with a rag to smooth out any imperfections in the gasket material.

Whats the torque on them?

Torque them down as you would any other 10mm bolts. Very cautiously.

the cause of almost all oil leaks when they are not straightened out.

I'm not too sure about that because if the sealant is getting tacky then it is "setting" and will not adhere as well to the surface you are attaching to. It may sound like a bunch if shi*, but it is true.



How to Replace An Oil Pan Gasket

By: Danomite



1) Remove oil pan

2) Clean oil pan and bottom of block (making sure to remove ALL old sealant from cracks) using med sandpaper (180-220) or diegrinder and scotchbrite pad

3) FLATTEN BOLT HOLES!

4) Wipe pan dry and apply sealant, preferrably hi-temp silicone, with 1/8" bead making sure to completely surround all bolt holes. You may want to be a little more liberal at the back of the engine (motormounts)

5) Wipe the mating surface on the block dry from all oil and attach the pan. install the blots hand tight ( I ues a socket and extension ) and let it set at least 1 hour (longer is better)

6) Remove the bolts one at a time and apply silicone to the threads, reinstall and tighten. 10MM Bolts should be faily tight (approx 10 ftlbs) and motormount bolts should be tight-dont know the torque spec.

7) Install T-78 turbo and fill engine with oil. Check for leaks.



If you crank on the 10mm bolts you will flare the pan holes again and can break the seal from the pan.

ari , rotary performance, sold me some orange sealant a little expensive but i have done several jobs including my oil pan and none of them leak.
