Bubba at it again...
Well Bubba struck again. This time on my '89 350 Sub. The very first exhaust manifold to head bolt is striped! :eek: :eek: He tried to fix the problem by inserting a larger bolt and then tightening. :confused: :confused: Now it's leaking with the give-away tick-tick sound.
My question---How should I fix the bolt hole which is in the head?? Remove the head first. Try to drill a larger hole thru the existing exhaust manifold bolt hole and the the head and then re-tap the hole? Remove the exhaust manifold first? I might have enough room to access the bolt hole without removing the head....
Anyone use those insert kits. Will one work in this situation?
Is there a rapid temporty fix until the weather warms?
Thanks
Len

Re: Bubba at it again... (1970 Stingray)
Easy fix with a Helicoil kit and a 25/64" drill. The 3/8"-16 Helicoil kit (12 inserts, Helicoil tap, and insertion tool) you need is #5521-6, plus a 25/64" drill bit. Pull the manifold, drill out the hole, tap it, insert the Helicoil, and you're good to go.
