Removing A.I.R. tube fittings from manifolds?

**scuncio** · #1 07-02-2009, 04:05 AM

Can anyone share a good trick for removing these tube nuts from the exhaust manifolds? A few of the nuts already have the hex head snapped off - on these, should I drill out the ID before using an EZ-out?

Thanks,
Tony

FYI, KROIL is a very good penetrating fluid.......

May we assume you've heated the area with a oxy/acet torch ???

Yes, I did heat the area with a torch but two of the fittings will not budge. Unfortunately these are the fittings that have been sheared off so they are even tougher to access. I have been using PB Blaster.

I had that happen to me,and I was able to heat them and grab what was left of the sheared nut with a needle nose....AAAARRRGH!

I know the feeling...I had to have 2 of mine drilled out. Fortunately I have a friend that owns a machine shop and he drilled them out for me...I didn't even need to re tap the holes, he did a good job.

MAP gas and an easy out.

I was told by an old timer who was a tool and die maker. You can heat up a rusted part and then cool it very quickly with water? I did it with an exhaust pipe and I was able to twist the 2 pipes apart with my hands. So I would think it would work for your manifold also. I guess the theory is when you put the cold water to the hot surface it loosens up the rust? Not sure if you want to give it a try?
