broken bolt help
1 Attachment(s)
Hey all,
Long time no post ( for me anyways )
I just picked up a 1967 Ford Ranger, and the 352 has really bad exhaust leaks. went to swap out manifold gaskets, and found 4 manifold blot broken off in the heads. My question is, should I pull the motor to get at the bolts, or should I just yank the topend?
the only difference I can see between the 2 processes is, the top end is gonna cost me a gasket set, but I can sheck out the internals too, which I see as an advantage. Heres a pic of the truck, and I will get some more up in the photo gallery as soon as possible.

just take the head of it will be easier to get at and you can see what you are doing if the bolt has broken off flush to the head
cheers stuart

I have a 67 F250 that I swapped the old 352 out for a 390. When I was doing this swap I needed to pull the car manifolds off the 390 and put on the 352 truck manifolds. The first thing I done was I ran the 390 until it was good and hot and then sprayed the exhaust manifold bolts with WD40. Well this partly worked, I still broke 4 of the exhaust manifold bolts. What I did, is I used a pair of vise grips on the broken ends of the exhaust bolt. It worked on gettting 3 of them out but the fourth one I had to drill a hole all the way through the bolt. I started with a small bit then kept stepping up in bit sizes until I was just a little bit smaller than the thread size. I then used a easy out and it came right out. I had the motor out of the truck when I did this, you might be able to drill it with the motor in the truck. If not you might have to pull the head to get the broken bolts out. I have not seen a FE yet that doesn't break exhaust manifold bolts when trying to get them out.

thanks for the input guys, I have made the command decision to r&r the top end, that way if those broken blots give me to much greif, I'll just take the heads into the machine shop to have them bored out.
