Even the generic Black RTV has done me fine, and thats using all sumps from ones with big dings and nicks in them to freshies.

im with tak, why so brand paranoid? ive used metal fascia and gutter sealant @ $4 a tube and its held for years on sumps and diffs

EDIT: and exhausts! lol

If you have troubles getting the sump to seal with RTV sealer you just need to be more careful cleaning up the surfaces.

Use both a water based and an oil based solvent on the surfaces. I rub down the surfaces with metho and get a fresh rag and then do it again carby clean.

I would have done 10 sumps like this and have never seen a leak

Clean with wire wheel on drill. You must clean the sump out after wards.
Blade on the engine as its a smooth surface.

I used a blade to seperate baffle, sump, and block, and then remove as much sealant as possible. After which it was a wire brush until spotless followed by a wipe with petrol then washed out with water and left to dry.

Also bent the pan and baffle back to dead flat.

i usually clean both surfaces with turps/carby cleaner/thinners/something..... it eats thru the toyota sump goo enough to provide a clean surface for re-sealing.

I've never had a leak either.... even on ones were i have just used a paint scraper to get the old sealant stuff off, and just whacked new sealant on.

Loctite have an instant gasket maker. Its a black sealant and comes in a presure pack type can. Its not spray on its proper gasket stuff. I work at a car dealer we use it to seal stuff like that and in the time ive been there i have never seen any leaks with this stuff. I used it on my diff in my celica and not a single sign of leakage!!
