I used right stuff to seal my intake manifold, worked great
I also used it to seal some gaps in grommets where tubeing or wires went thru the firewall when i installed my vintage air.

If you want the best of both worlds, right stuff is an elastomeric (moisture cure) that will seal most any surface, and can be put into service as soon as it is.
Black rtv can flex, allowing it to retain its bonds between two different material types that will heat and cool at different speeds
Grey rtv has higher density when cured.

So which rtv is better for the oil pan, rear main and front timing cover there are to many mixed feelings
One has to be better than the other, the black stuff says maximum oil resistance and the.
Here's a question:what's the difference between the black and the gray right stuff
I know permatex says one is for domestics and the other for imports but does it matter?
