I can't find a ford 12 bolt gasket anywhere.

I have a 97 f150 4x4 supercab with 5.4 triton

The only cover gaset I can find is 10 bolt mine has 12



what is going on?

 

There is no gasket. You use some of that silicone/rubber gasket sealant stuff instead.

 

Yeah , mine didn't come with a gasket from the factory..

 

i did it still is leaking!

 

Then you did something wrong. There is no gasket from the factory. RTV is all that's needed to seal it, but you must prep both surfaces properly and allow it to cure a bit before refilling.

Scrape both surfaces clean, then wipe both of them down with Mineral Spirits to dissolve any remaining gasket material. Clean all dripping oil off the faces, and spray them down with brake cleaner or alcohol to remove any residue. Apply a narrow bead around the perimeter of the cover or the housing (no need to do both) being sure to make a complete ring around the bolt holes. Install the cover without shifting and sliding it around any more than necessary. Torque the bolts to (IIRC) 13 ft*lbs, and do it evenly in stages all the way around the cover so as not to distort it. The longer you can let it cure before refilling, the better off you are.

I've never had one leak after doing it that way.
