What kind of permatex do I need for the intake to head surface? Stupid *** me didnt put a rags in the boot and dropped a nut down in there and then had to go fishin. So I took the intake off of the head, and need to reseal it. Thanks for the help.

 

It's rubber RTV. International sells a big tube of it. Check your IH dealer.

 

If you want to use the Permatex brand sealant you're looking for the "ultra gray". I've used it and the Ford/International gray stuff and from what I can tell they are almost identical. Both rated as a high torque load RTV sealant.

The nice thing about it is it comes in the same size tube as the rest of the permatex products and only costs marginally more than plain old black or blue.

 

ok thanks, Curtis and Scott, heading out to find some.
