Sealing Case halves with.....? What does everyone prefer?

[cmeripper26]

Putting motors back together i generally use 1211 to seal the case halves and dont use anything around the outer edge on the oil seals and have never had a problem. Does anybody use anything on the outside edge of the oil seals before sealing the case halves together....just curious cuz i always assemble my motors to manual spec.... and they never specify to use anything on the outside edge of the oil seals.

i use honda bond and leave the seals dry(no sealant)

Did u say 1211????

Are you kidding me? Everyone knows that 518 is the only way to go!!!

A very thin film of 1211 on the mating surfaces and a little bit on the outer seal surfaces.

I never put anything on the outer seal surface... i always go by manual specs and havent had a problem.... was just thinking of putting a little 1211 around the outer edge of the seals to see how that works.

1211 is good stuff i use that all the time and i have assembled motors both ways just to see if it would make a difference and it really doesnt

I use 1211, too. On a new engine I could see not putting sealant on the crank seals, but for a used engine I'd prefer to have some extra insurance that I've sealed up all worn or corroded mating surfaces.

Been using 518 for a few years, no issues.
I dont think one is better than the other.

If its meant for the job then thats all that matters. I like 1211 because its easy to use, yamabond is too stringy but does it matter. If you cases don't leak then its a done job.

1211 is great for sealing cases
never applied it to a gasket tho, besides for the copper head gaskets.
