I pulled my AIR pump and most of the tubing over the weekend, and cut the tubing fairly close to the manifold, thinking I could then get a large socket over it and twist it out.

The problem: It won't come out. I've soaked it with WD40, and Tri-Flow Superior Lubricant, brought the headers up to running temp, and they still won't come off. I'm darn near rounding the nuts from cranking on the so hard, and I still can't get them.

I'm out of ideas. For temp fix I thought I'd jam a thick screw threaded bolt down the pipe, but I'd much rather throw the 22mm plugs into the holes if/when I can get the stupid existing nuts out.

Thanks for all suggestions.

 

Try using Sea Foam's Deep Creep its the best stuff I have used! Or try heating up the nuts with a torch and then imeadiately melt some wax on the nut....the wax should get into the threads and help loosen the nut, get a wrench on them right away. Hope that helps.

PB Blaster and a six point socket.

 

If PB doesnt loosen em, get out an OXY torch and heat it up real good. PErsonally, even with a torch and a week's worth of PB, mine wouldn't budge. Ended up with headers shortly after

 

liquid wrench works pretty good too. And use anti seize on the plug, so it will be easy to remove if you need to.
