Although I have almost always seen an anaerobic sealer recommended for sealing crankcase halves, I’ve also seen folks recommending and using Permatex Motoseal gasket maker. While rebuilding one of my motors, I contacted the Permatex tech support group and inquired about their anaerobic sealant or their Motoseal product for use in 2-cycle crankcases. They actually recommended the Motoseal. I’m certainly no expert, but I’d like to hear other’s thoughts on this. Here’s the Motoseal link. Sounds like it would work?
