Need help with this one guys. so any input would help
Engine is a 22RE, I have an Exhaust mainifold leak AGAIN the last two bolts (Closest to the firewall) Are not tightening down. so I have an exhaust leak and the "tick tick tick" is back again
The holes had been helicoiled about 5 years ago, and stripped out about 6 months ago.. the leak came back.
The holes have now been tapped out to the biggest size possible 3/4 " I belive and larger bolts were put in. This held for a couple months and now the tick tick is back again.. and I cannot tighten those bolts any tighter (they just start to free spin).
So How do I fix this problem ? I cannot tap to any bigger of a size.
I was thinking I could maybe WELD a stud into the hole ? But I think that might warp the head. ???
than I was also wondering about this Stuff.

Could I maybe fill the hole with this stuff than thread a stud into it and let it dry ? would it hold up to the heat ?
Any other Idea's Weld the mainifold to the head ? Use two gaskets and lots of RTV Sealent ? Duct tape ? A Nail ?
