Reply To: spaghetti seal AND Permatex 51813?

[Bob Wight]

Permatex 51813 is an anaerobic sealer equivalent to the OMC gel seal. As far as approaches, gel seal wasn’t around when these motors were originally assembled so 847 will work in conjunction with the spaghetti seal. Some folks feel that the modern day 847 is messy and starts to cure before the case halves are fully assembled, possibly leading to gaps in the finished joint. So this is why some just use the 847 to hold the spaghetti seal in place, then use the gel seal for the joint faces. There are certainly others with more experience than me (like fleetwin!) who could speak more about this.
