Teflon or Rubber rear main seal?

Which one will last and be a better buy. Can get either for same price at autozone and they are both fel-pro brand

I never used the teflons, always the standard rubber seals. The last few I used felpro #BS11829-1 Offset Double Lip Rubber Seals. Used them on machined and used, cranks without any problems. I also install them staggered or offset (ends not flush to block and cap) though.

Re: Teflon or Rubber rear main seal?

Resurrection....

I went to get a new Rear Main Seal, and the guy asked me if I wanted the single or double lip. I chose the double lip.

Anyone have experience with one over the other?

Also any tips on install?

Thanks
