As you may all know I do make the cork ones, but was approached about making these. Kind of nice to not have to throw them away every time. These are also 1/32" thicker than the OEM gaskets, and make a nice tight seal.

I'll be starting to ship this next Monday on these, and they can be combined on the website with other GB items.

Let me know if you want in.

Awesome! These should probably be glued to the valve cover. Silicone has a tendency to be extra slippery and may move out of place with crankcase vacuum.

For a general RTV adhesive I've been really impressed with Momentive RTV159 or RTV103 formulations ( Momentive RTV159 on McMaster Momentive RTV103 on McMaster ). I've used it to adhere High temp silicone parts to 316 stainless steel at work for a few abusive conditions.

It held up to high/low temperatures as well as jet fuel, hydraulic fluid, salt spray, oil and the bond was still so strong that parts of the item that was glued down would rip off and stay stuck to the metal when we tried to pull it off.

For preparation we just scuffed the stainless and silicone with sandpaper and then cleaned with solvent and allowed to dry, applied a thin bead of RTV159 and lightly clamped for 24 hours. Wait total of 72 hours before install.

We had issues with McMaster not wanting to ship RTV159 to California so RTV103 is a suitable substitute, not as strong though.

That being said, I'd like 2 sets.
