Leaky sump gasket

My sump plate isn't sealing against the sump very well. The aluminium is very pitted. What the best route to take. I'm thinking thicker gaskets or maybe silicone.

 

Use silicone but sparingly.

 

Use silicone sheet and cut a gasket

 

I’ve recently fitted a silicone gasket kit to my beetle. No leaks at all.

Hylomar or Curil-T: something non-setting. Silicone is horrible stuff.

 

Will try this

 

And it can break off causing alarming damage ...turning the day into a shocking state of affairs .

 

If and only if the engine block can be got oil free for a while it can be possible to make a smooth surface with something like good old JB weld.
BUT you have to clean it thoroughly.
Silicone sealant wont stick properly to oily metal either.
Go for the silicone sheet idea.
Then if it still leaks the engine comes out, you turn the engine block over and clean it thoroughly ending up with carburettor cleaner to degrease then surface it with JB weld, sanding it flat carefully so the silicone seal has a chance.

Then if it still leaks , build a new engine with a newer block or exchange it for a recon engine with a different set of problems.

 

Its a vege engine which was not long fitted before I purchased it last year. I've just made a gasket out of uncured rubber which we use at work which withstands very high temperatures. Will report back how I get on.

 

Vege has already built that engine out of the pile of stuff over Snotty's fence.
