Which type of silicone would you reccomend for use with a regular gasket when installing a water pump on an RX-7? The ultra high temp Orangey Permatex stuff or the normal, lower temp Blue stuff?

Thanks,

Ray

As a Tennesse Alumni I saw this comin a mile away...

Yeah, hood latch boy, looks like the car and and your "Tennessee pogo stick" you keep in the back, know whats really going on.

I use ultra black kind of like zip ties (it works for everything!) but technically ultra grey is probably "best" for a water pump when not using a gasket. Don't take my word for it, read up:

+1. The only real gaskets on our challege Spider was the head gasket and valve cover gaskets. All the rest were the gray stuff- front cover, lower and upper oil pan, intake, etc.

Use a very small bead (the trigger handle helps), hand tighten, wait 10min, and then fully torque. By letting it partially set, it seems to work a little better.

Um the colors for ILLINOIS are Navy and Orange. SO use the Navy one.

I'd just buy the factory gasket. Works great and lasts forever and not to pricey.

I read a article on replacing a 2nd Gen RX-7 water pump which reccomened using the stock gaskets and silicone. Is this a bad idea?

Use the silicone which can handle the extreme heat of a rotary, much higher temps than a boinger

I used stock gaskets no silicone for my 2nd gen 7. No leaks!

You don't need silicon if you use the stock gasket. I've never had a WP gasket leak in any of my RX7s.

When you guys talk about the stock gaskets sealing perfectly, are we talking the asbestos gaskets or the non-asbestos gaskets? I got some non-asbestos throttle body and intake manifold gaskets for my RX-7s and was planning to use the Permatex copper-colored silicone to seal it all up.
