I've got a question for you all. I finally succeeded in removing the intake manifold so I can clean out the EGR ports, and I'm a bit stuck on removing the EGR valve. The two bolts are rusted on nice and solid (what a surprise, an exhaust part rusted on, who would have thought?) and I'm looking at options for getting them off.

I've heard torching them off is a good idea. What kind of torch could I buy for this? I'd probably like a small one to do this job. I've read that heating the runner area could break loose the carbon clogging the EGR ports, so that would be an added bonus.

So far, I've tried putting a 12mm wrench on, drenching the bolts with Liquid Wrench and giving it a good whack with a hammer. Needless to say, it hasn't worked thus far.

Here's what I'm dealing with:

 

MAPP Gas. Burns a ton hotter than Propane and comes in the same package. You should procure it at a local hardware store. It might be in the plumbing section. Try torching the bolts with MAPP then spraying lubricant over the bolts while they are still super hot, the heat will suck the lubricant into the threads and you should break them free with no trouble.


Works on rusted exhaust bolts when I was in Minnesota.
