STC fitting blew out and cracked cover case housing

[BLKF250]

I got finish racing the other day and my STC fitting blew out and i got the latest STC fitting from ford (the one nut unit) and it blew out bad and cracked the cover case housing for the rear main seal... Anyone know how this would happen? to much pressure?

mine did the exact same thing. luckaily the dealer fixed it for free since it happend a week after i bought it. the old stc fittings are pressed on the oil pump and the newer version is threaded on to prevent it from blowing it out. its gonna take a decent amount of time to get this all fixed. you have to drop the tranny to be able to take the rear plate off.

so did the new STC fitting blow or the old one?

[jsr86]

the old one blew.

[Abrannan19]

right..I understood that on yours, but didn't fully understand that on the OP

I actually had the new STC fitting and blew that one but ford came out with a even NEWER verison of it its like $40 bucks with gaskets and new bolts for the fitting and HPOP and gaskets for the turbo for the 05 trucks.. took me four hours to drop the transmission today iam getting the cover case housing for the rear main seal tomorrow and in stall it this weekend hopefully get the truck running again by monday or tuesday...

What's the part number of the new STC fitting and gasket kit?

[BLKF250]

It all comes together the part number is 4C3Z-9B246-E

part number is correct and remember to change the oil rail plugs while in there, and the updated turbo drain and feed tube.

Are those included in the kit or do you have the part numbers for those? If I'm going to be tearing it down, just want to make sure I have everything I need. Thanks!
