If you're welder/machinist doesnt have the kit, I still have one from when I did mine.

Please send it to me. I will pay you what ever you need for it and shipping. That way I have it if I need it.

Box from Patriot arrived this evening!

Yep,,,it was my head. Patriot stepped up to the plate and fixed the head for me.

They actually have a 90 day warranty (had the heads a lot longer than that

) but, said that the head shouldn't have had that issue and repaired it for me. The area that I thought was a crack was actually not a crack but a mark. The place that leaked was on the short side radius and it was a small pit in the casting that surfaced after the machining and use.

Its all fixed and ready to install.

Got a TIG machine all lined up to borrow to fix the starter mount, found a skilled welder buddy and all that left is to get hot. Thanks to 67Ranger, I will have a helicoil kit on the way.

Thanks Chad at Patriot for all your help and patience!
