Hi guys
For rebuilding a disco 200tdi engine can i use normal every day silicone or does it have to be for engines as in the past i have used RED Hemertite for sumps, timing case-block and flywheel housing-block but the Haynes book is saying RTV silicone.

Also when i removed the ladder frame and sump there was no gaskets used but what looks like silicone, i have just received a bottom end gasket set but i don't see a sump or ladder frame gasket, should there be or are these gaskets separate items or do they just use silicone :confused:
 
cheers, when i thought about it i couldnt remember if it was the ladder frame or back of the block that i used RTV, or both. Cheers flos
 
Any automotive shop sells it but I got mine from my local LR Indy in a grease gun sized cartridge because it was cheaper but I had loads left over so I filled a few gaps in my garage roof with the remainder.
 
For information. RTV means "Room temperature vulcanisation". RTV silicone is cured when exposed to moist air and gives off a odour similar to that of Vinegar when curing.
