A couple months ago I contacted Real Gaskets Tennessee (who made the very good silicone oil pan gasket) and requested that they begin making a valve cover gasket and a valley pan gasket. They asked me to mail them a new set of gaskets to use for a template.

Well... lo and behold they shipped me a set of silicone valve cover gaskets and a silicone valley pan gasket. Hopefully I can get the gaskets installed soon and begin testing. I am going to have to tell them at the very least to tone down the torque numbers but those numbers on the package really refer to the limits of the silicone gasket itself not the sheet metal valley pan or the valve cover limits. As we all know they are much lower.

I will keep you posted...

What about the torque specs for their oil-pan gasket?

What about the torque specs for their oil-pan gasket?
By Ted - 2 Months Ago
When I installed the Real Gaskets Tennessee (RGT) oil pan gasket on the 312 dyno mule, the instructions called for the same 20-25 in/lbs torque value as the shown on packaging pictures posted by Daniel.  That’s a very small torque value and especially if comparing it to 20-25 ft/lb.  I had four in/lb torque wrenches and there was only one of those that would go low enough to do the 20-25 in/lb spec.  Here’s the link to the RGT oil pan gasket when it was installed on the dyno mule for testing.

RGT has told me that they plan to offer the new gaskets in their online store within a couple weeks. The valve cover gaskets worked really well. I did not run the valley pan gasket on an engine, but did fit one up to a bare block/valley pan I had in the garage and tested the fit. It was very good. I do believe these will be great options.

Let us know when they can be ordered. I want to order their C4/C5 pan gasket as well. Might as well order all at once to save shipping costs.

The gaskets are live on the Real Gaskets Tennessee website. Again, I have nothing to do with all of this other than encouraging this company to produce the gaskets. I receive no commission, nor am I any part of setting the retail price. Wink

Ted, in the valve cover tests I did, I do believe one can go a good 10 in/lbs more in torque and not experience any distortion of the gasket. I did not go further than 35 in/lbs, but do wonder if they could not take more.

While I did express this to the company, they still kept the torque limit rather low

Thank you, Dan. I've added them to my shopping list, but I'll wait until the valley-cover gasket is also available before I order.

Thanks for all the effort - we now have a couple more items updated to modern world technology that was long overdue....

Stupid question...The description makes it sound like only one comes in the package.  Is this for both sides?

The valve-cover gaskets are sold in pairs for $47. The valley cover is now available as well for $32.50.

Thanks 55 I'm a bonehead...I'm not used to hearing these called pushrod cover so I would have ordered the wrong thing.
