Yanmar injector pump sealant

[heygus]

Anyone know for sure what type of sealant is used on the injector pump for a Yanmar 2GM20F YEU.
Had to replace the timing cover gasket. Seems like they used black RTV for the cover gasket, and some type of anerobic sealant for the injector pump. Since the Yanmar manual calls for a type of thread lock compound that isn't available, I'm guessing that blue loctite would work. Called Torreson Marine, they said they'd call back. Sent them an email and haven't heard a thing.
Thanks in advance
