Removing Tail Pipes From A Stock Exhaust

[bwaz]

Without a set of torches in my garage, anyone have any solutions to removing old rusted in tailpipes from a stock muffler? Tried twisting, and cutting one to try and pry the remaining pipe out, but still no @#*&*^ luck

Get the biggest pair of vise grips or waterpump pliers you can find and start squishing the tube in the muffler the tailpipe goes into. Not so much as to put permanent dints in it but enough to flex it and break the bond between the muff and tailpipe, work your way all around it so it doesn't become a permanent oval shape, but crunching noises are good, lots of wd-40, squishing and hammering on the sides and it should start to work loose, maybe.

lots of WD40 and an excessively large persuasion stick.  :lol:

i'm not busting balls here, but i am a firm believer that the whole wd40 works to free stuck bolts is a myth.

wd stands for \"water displacement\". i've heard of body guys spraying it on a patch of bare metal so it wont rust. bike chains so they wont rust. i use it on bolts that are subjected to the elements before i put on the nut (roofrack clamp wingnuts, bumper mounting bolts, etc). i keep a can around, but i rarely use it. my boss use to swear by the stuff until i drilled it into his head that it doesnt work, and now all we use is rost off.

i have found the best stuff to free stuck bolts is pb blaster, rost off, or liquid wrench.

and at canadian tire you can find small disposable torches that are perfect for the garage. i used one to free up alot of stuck bolts when i disassembled my 56 and they work well.

- dose stuck bolt/nut with liquid wrench
- rap on it with a hammer to \"shock\" it loose
- get some heat from your torch on it
- turn bolt/nut out

Sorry, I should have said \"penetrating oil\" you are right WD-40 is pretty weak but if it's the only thing you have at your disposal it's better than nothing.  My favorite weapon is a mix of Tumbler penetrating oil (a commercial shop jobber brand) and gear oil or 10w40. Soaks in and sticks around for later. Even better with a few heat/spray cycles, smokey but effective.

Has anyone ever used juts plain brake fluid?

[BUSDADDY]

Brake fluid is water based E (well glycol to be exact), It may feel a little slippery but it's only going to make rust worse as it attracts moisture. Penetrating oils creep between the rust and their lubricating qualities allow movement between the dry sharp cornered oxide. Adding heat opens up the small cracks and thins the oils so they penetrate further, the cooling cycle also draws it in even further.

no.

imho, brake fluid is horrible stuff. not only would it be difficult to apply, it's messy, ruins paint, stinks and should be left for the brakes, clutch slave cylinders, and nothing else.

i used brake fluid when i made this:



though really only to prime the metal surface

salt water, lemon juice, and bleach did most of the rustifying

which just goes to prove that...

ya, that was the point

And I don't even give it that respect!
