breaking loose muffler bolts?

[Atimm693]

No type of lubricant will do any good if there aren't any exposed threads. Spraying anything on a bolt head just makes it slippery and more likely to round. Even then I find their usefulness limited.

Best thing you can do is heat and impact. Use a hammer and a wrench if you have to.

Y'all scare me with the impacts..you don't have the 'Feel' you need too... Seen a wheel barrel full of broken bolts in the past,, on acount of em

Thanks, all.
Got 'em broke loose just with a day's soaking with PB Blaster and a box-end wrench. Must not have been too bad.
But... the other tips may come in handy in the very near future.

Some impacts are a lot better than others when it comes to trigger feel. Get a good one and you can give as much or as little as you want, and align the socket so you can see the letters move if the bolt turns one way or the other.

In my experience the shock of an impact wrench is much better at breaking things loose than a long steady pull of a breaker bar or similar.

My relationship with impacts is of the "cold dead hands" variety.
