Manifold Replacement?
 

My exhaust manifolds on my 8Ba are cracked and in bad shape. Are they known for breaking upon removal or do I have a chance at getting these out with minimal problems? Anyone have a suggestion? Thanks. Luke

Find a replacement before you try taking the old ones off. Probably better than trying to weld yours.

Im not going to repair them, I bought a replacement set last year already, just wondering how hard they come out.

If your new manifolds don't work out post a picture of originals and I will look in the shed. I see your in Wisconsin come pick up a set, free to good home. Dave/Green Bay

You can be assured that the bolts will be a bugger to get out but because you are going to toss the old ones, you can break them apart to get at those stubborn bolts if needed.

Im just hesitant to try and take the bolts out. Thanks for the offer!

I just don't want to end up pulling the damn motor to retap or something.

Exhaust bolts can be the hardest bolts to remove on an engine.

If you break off a bolt, don't be surprised. They go thru many, many heat and cool cycles which anneals them and makes them soft. We see a lot of them at our machine shop. if not enough sticks out to use a vice grips on it, we weld a nut to the stub. The heat of the welding helps loosen it up. You don't have to pull the motor.

Use lots of 50/50 mix over a few days make sure you ude a 6point socket, you might have to make one to fit.

I seldom have had a problem with exhaust manifold bolts. You've got a better than average chance of getting them out without breaking one.

Huh sounds pretty promising! Probably give it a shot after the Iola Old Car show swap meet this weekend.

And when you put on the new set, use brass nuts; At a minimum they will be easy to turn off (with a little heat) and not break the studs.

I recently has some lawnmower blades that wouldn't come off with my impact wrench. I put some 50/50 on it waited 10 minutes and all 3 came right off. I wouldn't believe it if I didn't see it.
