Green Sealant Type?

No idea, but I will tell you whoever did this does not know what they are doing.  The IMS flange uses outside seals to seal to the cases and should never have sealant applied to them as the sealant will actually cause a leak, not stop it.  Secondly, the three peripheral bolts are micro encapsulated bolts, which again do not require any sealant for the same reason.

I actually know Logray, but again, such sealant use on the flange perimeter and bolts is both unnecessary and can actually be detrimental and end up causing leaks.  Green Loctite on the center bolt is correct as it is a wicking sealant to prevent any potential leak if the internal o-ring seal on the center bolt fails.


We have installed a lot of IMS retrofits over the last nine years, and we never used sealant, and have not had any come back with leaks.  Anyone that has taken Jake Raby's engine rebuild school classes will tell you the same thing, and Jake developed the process, tooling, and actual replacement bearings in conjunction with LN Engineering.
