Ok I'm doin my oil pump and seals and I found a kit that has a gasket for the pump itself. All I have seen is people using an adhesive sealant, any feed back on whether I should use the gasket or no would be great thanks guys.

No gasket! Just clean the mating surfaces carefully and make a thin, continuous bead of Permatex Ultra-Grey sealant--it's a Subaru approved substitute (you don't need the expensive anaerobic sealant.)

 

Follow the "beergarden" photo for where the bead goes but do a neater job than he did! You don't want any to splooge out into the oil chambers.

And make sure the o-ring is properly positioned before you close it up.

 

Good luck.

One more thing--be sure the backing plate screws (the 5 flathead phillips) are tight. If any have loosened use Loctite on them.

No gasket! Just a thin layer of silicone and the o-ring. My favorite stuff is permatex ultra copper. But any quality brand is fine too.

Which is why you use anaerobic, because then it doesn't matter if any "splooge" comes out into the pump chamber. It won't dry. I just took the front cover plate off of a transmission that had been sealed with Anaerobic. 25 years and the extra that got squeezed out STILL was not dried. It was tacky and malleable like it had just come out of the tube.
