Rusty/frozen manifold bolts: Soaking the bolts to be removed hasn't worked. I have had good luck removing rusty bolts by heating them and melting a candle around them, which will usually flow into the threads and allow a previously frozen bolt be removed. Heating, then quenching with ice water has worked before. This time, I've been unsuccessful with either.
I have a Ford integral-intake engine, that has several exhaust manifold bolts stuck. I have resisted breaking the bolts, so far, and have used a variety of lubes to soak the bolts. However, after two weeks of soaking, heating, and trying to remove the bolts, I've been able to remove only one bolt!
I'm beginning to wish I'd stayed with Chevy engines, as this is the first time I've experienced manifold bolts stuck this badly. Of the two Ford engines (200 inchers) I've attempted to work on, lately, both have the same danged problem!
Anyone have advice for removing these bolts, without breaking them off, re-drilling, and re-threading them?
I also need help with stop using profanity, which stems from frustration! It hasn't seemed to help any!
