Block nicely bored 10 over. Note WSM has only 10 over pistons at this time. About to reassemble and note that the sealant called for is Loctite 518 ultra blue silicon. Looked for said beast and come up with Anaerobic, which I normally use. Looked at loctite ultra blue and come up with the product under a different number. The original sealant in the motor is black on the upper seal/bearing housing and clear on the crankcase flange, Any thoughts on this?

Loc-tite 518 is not blue silicone, it is red anaerobic sealant and is the correct product to use for sealing the crankcase.

I know that the latest 518 is an anaerobic. The manual calls for a silicon Ultra blue. Is there an update on this.
