Rusty Hose fitting removal
Anyone have any good tips on how to remove a rust hose fitting from an aluminum intake manifold? They have been in there a while and I suspect that previous owner did not want to chance cracking it...
Thanks

Get a propane torch. Heat up the fitting. Get a candle and place it all around the fitting so that the wax runs down into the threaded area. Give it a shot. You can also heat the aluminum fitting boss and try the wax trick or just heat the boss and try to turn it. Aluminum absorbs heat faster than iron and expands faster.

:iagree:
It's not worth the risk of cracking the intake by heating the fitting. Soak it in Kroil or PB Blaster for two days, then try. If that doesn't work, do the candle thing. Last chance is the torch on the manifold, but be careful. I think line wrenches are also called flare nut wrenches.

My opinion: If it's rusted into the aluminum manifold that bad, then the
aluminum around the fitting is corroded, too. Even if you get it out, there
may not be much to screw a new one back into.
POR15 until it lets go for good.

[ Personally, my favorite is PB Blaster.

:iagree: Get some PB Blaster and give it time to work. The stuff is amazing BUT sometimes you have to be patient. Let it soak a couple of days. Then give it a twist and :thumbs:

Re: Rusty Hose fitting removal (R. Bruno)
Well all... one of the fittings came out... after a little soaking with PB... I used the impact wrench on low and it broke loose. The other fitting in the front... wont budge, so for now, it will stay in there for a few more years... I dont have the guts to really lean into it... That on has the funny slot that is cut accross the front of the fitting...
Thanks for all the advice...
