Hello. Absolutely have done what you are doing! The overnight soaking from Liquid Wrench, or your favorite stuff is a good start. I snapped one of the 3, my bad. I have not used a torch, because I was a firebug as a kid and scared the bejeebers from me! Dale

 

Mine has 2 bolts and 1 stud connected to the exhaust manifold. By the way your talking it sounds like you guys have 3 bolts.... My car is an 83, could that be why it's different?

 

Snap it off and drill it out later if you're going to remove the head, else torch it for a few minutes, then just twist it back and forth until it loosens up.

 

My 3 exhaust manifold to down pipe nuts came off with ease.
Like they were put on just yesterday....and on a 30 yr old car
I doupt it.

They were brass nuts...with the slots on the sidewall...like the
wheel bearing securing castella nuts.

Don't know if they are stock item...but I'm glad the Previous
owner put them on. Try to find them for the replacements.


Z-On ...
