| RE: Rusty exhaust manifold bolts |

I just removed the exhaust manifold off of my 429 in a 69 engine bay, so I had to deal with double the effort w/rust and lack of room! I went with the other suggestions already posted as well as using 2 other tips:
1- Always use a 6 point wrench/socket if you can, a 12-point will round off the bolt just when you thought you got it loose.
2- Not sure if this is a problem for you, but I had a problem getting to some of the bolts and found I could only use small box wrenches on some bolts. Besides the lack of torque power, I had trouble even gripping the wrench so I made my own little 'invention'. I used a 6-point ratcheting socket which fit nice and snugly on the bolt. I looped a 6' piece of nylon rope (fairly thin stuff) through the other side of the wrench and looped the other end around the middle part of another wrench(you can use anything straight where you can get a good 2-hand grip on it). I got in a position directly in line with the path of the wrench (one time this was under the oil pan) and with my hands on either side of the rope used the straight bar/wrench to slowly pull down/up the wrench (similar to a seated row machine motion if your familiar with that). This gave me the extra torque power I needed to loosen the nuts. Worked like a charm. I would make sure the wrench is really snug on the bolt, but if it is, this acted like a giant breaker bar. The first 6 bolts took 3 hours, the last 8 with this took an hour, so it worked great for me.
Hope this helps!
