Can anyone recommend what sealant to use for refitting together crankcase halves?

I want to use some internals from one motor on another with the help of a wiser person, but they have asked me if there is a recommended sealant for our aircooled crankcases.

Cheers,
Brad.

Cool.
Thanks.
Now - any advice on where to buy.
I found somewhere in the US and France but they say it is flammable so it has to go by ground and not international?
Any Australian suppliers?
Or do one of you want to sell me some in a jar? I only need to do 2-3 engines (well do it 2-3 times anyway once both engines are put together).

I use a loctite 518, a modern flexable sealant that does not have a issue handling vibration.

Permatex aviation gasket maker/dressing ?

white bottle with tar like brown stuff yeah?

If so I use this and works awesome, I use it also on all paper and cork gaskets as a thin dressing as it stops the gaskets drying out and makes them way more oil and air tight.

Thanks folks.
I passed this info onto the in law who is doing the works for me.
He said he has the right gear already for it which is good.

Doesn't have a very high heat rating.

Yup, that's the stuff. Been ages since I used it hence my misspelling.

If the case reachs 300f then there is more to worry about than the sealant

Yes and No....its not uncommon to see that type of case temps in extreme motorsport.

I'm not saying its the norm for that temp, I'm just surprised that being a 'modern' sealant it wasn't rated to 200deg C like the others.

I'm sure its a great product, that does its job.😎
