Any real tips for helping remove exhaust manifolds without breaking Bolts??? thats what I'm looking for, not replacement bolts. Any ideas would be appreciated. Thanks ray:
Soak them for several days with Mouse Milk or the equivalent. The longer the better. Put a little pressure clockwise then back counter clockwise. Use a a short rachett to keep you from over doing it before it is ready. Whenever possible use an impact wrench. The vibration helps to break these loose.
I bought my car 10 years ago and has been sitting since after my buddies started givin me crap about it sitting in the yard i finnally registerd it. my manifolds are leaking ans sounds like a$$ i am dreading even sarting this part of the project even though i am not keeping this motor in the car has to be done for me to be happy about driving my 185000 mile 70 sky convertable i will keep you posted on my removal i may start mine in the am GOODLUCK

Did my manifold gaskets to day wasnt as bad as i thought. all my bolts came out a few stubborn ones drivers side only took i hr did it from the top. with a swivel ratchet 6 pt 9/16 and 14mm one short extension. pass side used the lift (my car is a/c) all the same sockets with one exception a ratchet wrench 14mm one the middle lower bolt with a pipe over it to break it free lower rear bolt was the only one i took out up in the air. never diconected the exhaust used a floot jack to hold up the engine pipe and manifold cleaned the gaskets used a little permatex copper the complete job took me 3 hrs of tough work and fiddleing car sounds much better with no leaks :beer a few beers a dip in the pool to cool me off
somtimes, it is wise to remove the fender liners, which is fairly easy to do. then u can give a good smack on each manifold bolt with a big ballpeen hammer. and it u twist off a stid, then u have a direct shot on the stud for drilling/easyouting.
Another alternative is to remove the heads with the exhaust manifolds attached and take these to a machine shop.
