Stupid question about RTV for our 7.3's, I used some black RTV on my aluminum plenums, stuff is really strong. I just noticed is said not for powerstroke diesels. Is there any reason why other than for not being able to withstand the boost?. I realize the grey is the stuff recommended, just did not have it hand.

I dont know about what would cause that to fail, but after using the grey Ford stuff, I wont ise anything else. That is some bad ass stuff.

It does. It's all we use now since it's quite a bit less money than the same stuff with different sticker on it.
The Permatex grey comes in two different versions, the High Torque stuff is (or was last I heard about a year ago) the same mfg for the stuff that comes in a Cummins tube. Not sure who Navistar was getting theres from. One of our Internatoinal dealers uses the Permatex stuff as well.
Biggest thing requardless of which brand is making sure the prep and application are done correctly IMO.
I use the Motorcraft TA-30 in the caulking tube, F7AZ-19G204-EA. Its black. Somewhere awhile back on another site I think there was a post that the TA-30 is for the intakes and the other stuff, Motorcraft TA-31, F5TZ-19G204-AB (also in a caulking tube) was for the rest of the engine. There was also a post that Yamabond#4 (motorcycle stuff) worked on intakes, too.
