Howdy!
1970 F600, 330 motor.
Just replaced the "Y" pipe. Leaks in 4 places btwn. exh. mani. & head. Any "quick fix" I can smear in there to get it through inspection? JB Weld?? Other?? Bolts are pretty bad (33 years old).
I removed the exh. manis. on a Chevy 350 once...what a night mare!

 

umm try putting some sheet mettal over it and rap it with duct tape not a little bit go around it like 30 times it will fix it for a while till it melts off just an idea it worked on my 302 for a week till i had time to get a new y pipe

 

Hahahahhahahahahahahahahahha! "Go around it with duct tape like 30 times". If I don't die from laughing right now, I'll die from the fumes!!
What about furnace cement? Is that the same as those muffler patch kits, or is it better??

 

lol duct tape solves all its like the force it has a light side and a dark side lol

 

I've gone as far as using two gaskets with high-temp silicone on all the surfaces (head-gasket / gasket-gasket / gasket-manifold).

Mine have been sealed like that for 2 1/2 years now.
