Gasket or silicone for rear end cover?
I'm fitting a Summit aluminum cover to my 10 bolt and it came with a gasket but the instructions say not to use a gasket and only to use silicone sealer. Just wondering what most people use when installing their rear end covers?

Thanks,

RTV, just make sure you let it cure properly before you fill the rear with oil.

RTV is great, you just need to follow directions.

Re: Gasket or silicone for rear end cover?
I normally use a gasket/sealer combination. But I have used just RTV also. And again let it cure before filling

I use a gasket with my Summit alum cover. Had a small leak at one point, but I snugged the bolts up a bit and that ended the issue.
