Getting ready to lower the intake onto my rebuilt 360. Everything I've ever read and done in regards to chevy v8's says to forget about the block wall (China wall) gaskets and just lay a bead of rtv down instead. Does this apply to FE engines as well? The heads and deck surfaces were milled a few thousandths to clean them up if that matters. The cork gaskets I have are pretty thick. Don't want any poor fitment or leaks. As always, thanks in advance

Yes. Bag the cork gaskets and use silicone. Setting the dizzy is a good way to get the intake placed.

 

For end seals I have had best luck with Ford TA-31 sealant. Actually made for diesels. Works best I have found

 

I used the cork gasket + a thin layer of prematex # 2 no leaks (yet)

 

I have always used the cork gaskets with never an issue. Just three weeks ago I used a bead of silicone and had a vacuum leak for the first time in the back. Go figure and since the intake was not going to come off for a third time it has been fun trying to fill the invisible, to me, gap in the back.

 

go to fordfe.com theres a big post on this subject, everything you need to know about installing the intake .

 

I was going to start a thread like this but let's keep this one going.

My main concern is the weight and setting the intake down straight onto the gaskets. The cork gets really slippery and slips around on occasion.

I'd like to get that grey Ford diesel silicone, is it available anywhere besides the dealer?

 

Not sure about getting the ford stuff anywhere but the dealer. I know I paid about $25 for a little tube of it from the dealer. I used it a few times building my last motor but I really don't like the way comes out. It's like real tacky right away. I believe it is good stuff though. For my intake I used the cork just because the Fel Pro stuff had adhesive on it. I was very impressed with how well that cork stuck to the block....normally the cork is all over the place.

 

Hmmm...... I bought a felpro set, when I get home I'll check if it has cork adhesive. I think I'm going to buy permatex gray, I read a couple of good reviews on it.

 

Amazon sells it, and everything else in the world. I used permatex gasket maker for my intake. Good stuff.

 

Where else? Amazon


The cork end seals with adhesive look tempting but they may vary a bit in thickness. I tried them out and then laid the intake for a trial fit. The intake sat too high and may not have come down enough when torquing. That might leave me a water port gap and definitely a mis-alignment where the head and intake meet. So I used the TA-31.

Good luck as I have had three failures already and will be going for #4 to seal the intake.

 

Permatex Ultra Black is designed for contact with oil.

 

My fel-pro gasket set did not come with the adhesive so I might leave the cork out. I was going to order the TA-31 sealant from that link but there is 8 bucks shipping, that makes it up there with the dealership. I'll try permatex ultra black or grey, I have to do some research and decide which one.

 

The grey was recommended to me for the third member and the ultra black for the intake.

 

I've used the Ultrain Blue, Black, Grey all for different purposes. Kind of whatever I have at the time and they all seem to work well with oil. I've used the blue and the black on 2 diff Mustangs rears I have and both are leak free and hold Mobil and Amsoil.
