[MustangSVT]

I am having problem removing an old water pipe... it just wont budge!! ive tried wd40 and bigger wrench... but still nothing..

This is a water pipe that goes to a water heater. (yep. replacing a water heater.)

If there are any good tools/hints, please help..

cast iron .

yeah ive thought about torch, but would it really do much??

thanx./

What pipe, copper or case iron? A little torch will do wonders heating it up and banging on it. Kryoil works great too. Careful using heat around something you've sprayed flameable WD40 with

Is it a copper pipe?

Can you get one of those little propane torches and heat it up a bit to help loosen it?

If all else fails use a BFH

Heated metal contracts and expands when cooled so yes it will definately help.

Spray some PB Blaster on it Or is it not rusted?

Go with the heat treatment. Can also try tightening it a fraction then try undoing it. Sometimes this can help. It can be enought too crack the " weld". Cast fittings are sooooo much fun!!!
