These two sealants are spot on for the job -

Id use something like this but sparingly as applying too much can see pieces break off and find their way into some strange places.

This seems a good sealant product, the seller claims its a high modulus acetic curing sealant -

Degrease all surfaces, apply silicon, I've used the ordinary from screwfix before, to the outer edge of the sump and around the securing holes. Attached the sump whilst still wet and tighten the bolts up. the silicon spreads and forms its own gasket. Do not let the silicon get into blind boltholes especially if it then sets driving home the bolt can cause castings to crack under the compression effect on the silicon. I would also put a dab under each bolt head so that has its own mini gasket as well. Never had a sump or water pump leak yet.

Would you expect an engine sump pan to get hotter then 200 degrees C ?
Most sealants seem to state sustained temps of 250C and short duration 300C +.

the one I mentioned above, IE,

is quoted as being suitable for crankcases so should work fine ?

Your sump pan will reach a temperature of around 130 deg C - the temperature of the oil at its hottest......that doesn't include air cooling of the sump, of course or the action of the oil cooler.

Will probably get the job done this next week using this

Apply the sealant the the sump and bolt on or apply the sealant to the sump and leave it to cure for 24 hours before fitting ?

A ring of sealant around the bolt holes or just run on the inside of the holes ?

Will this do for applying the sealant ? ........ I'll leave to set for 24 hours before I bolt it on !

Job done !

Lower bell housing plate removed for access to rear sump bolts.

Crank pulley removed to make it easier to clean engine block mating lip for sump.

Exhaust manifold loosened off so down pipe could be lowered to allow sump to drop off (with a bit of a struggle breaking old sealant).



Only hardship was running the gauntlet with the pour downs we're getting in the north east at present.
