Turns out the flange on my right pipe is partially cracked off. Apparently the nit wit who fitted the pipe, decided it would be ok. Well, after sealing the balance pipes it leaks arond the right exhaust nut, I suspect right at the point the flange is missing.
Has anyone welded a flange?
I think I can weld and grind down the missing part so it will be good as new.
Please let me know if any of you guys have tried this, or if anyone has a spare right pipe for and 74 850 laying around and needs a new owner.
