Default Necessary torch when installing OBX headers?

I just purchased OBX headers for my 98 Accord 4cyl, and I was going to install them myself. Thing is, i've heard from a few people that it's necessary to torch out really old bolts used in the factory installation of the exhaust manifold, in order to remove the old bolts? Is this true? I think some bolts down there will be WAY too tight to get rid of and they will be completely rusted, and will need a heat torch to burn and get rid of it. Whoever here has installed headers themselves, can you tell me what tools you used and some obstacles you had to face? Thanks.

If you let them soak in PB blaster or WB 40 for a while you may be able to get them with just a wrench. You could also probably drill them out, but its a whole lot easier just to torch them.

I personally didnt even waste time and just pulled out the torch.

Spray them as many times you can a day for at least 2 weeks in advance. That will help considerably. I used Liquid Wrench.

Default RE: Necessary torch when installing OBX headers?

So I guess I have to use the torch or else I'll have to shower the bolts in WD40 for a LONG time. It's funny how the Meineke guy said that you won't need to torch anything unless something is wrong with the factory exhaust manifold. Anyway, so I'm probably going to have to find someone with this torch? Anyone know where I can find one in Suffolk County, NY and how much they usually charge for doing it? Do the shops that have it actually just torch a few bolts for you?

I was also thinking about just using the WD40 and all the other fluids to help remove rust from bolts. Is it okay to mix all these fluids? Or Just stick with one? Which one's the best? Also, let's say I take off the gasket on my factory header (where it connects to the four exhaust valves in the engine), but realize that the bolts connecting the header to the catback or downpipe are really rusted. How am I supposed to drive it to someone who has a torch who can torch the bolts for me? Do I have to simply put it back on?

Also, do you need a torque wrench of some sort for this installation. I know the big impact wrench (usually used for lugnuts) probably won't fit in certain parts, but do I even need it? Or can I just apply as much torque as I can with my hand using a regular wrench.

Sorry for the load of questions. I just want to know all the stuff I need to watch out for when I install these, although I usually learn a lot by actually doing it, it always helps to have as much background knowledge as possible.

Y'know, I searched on eBay, but is it possible to do the torching myself with something like this?

http://cgi.ebay.com/ebaymotors/ws/eB...;rd=1&rd=1

It's basically a pen-sized flame torch that I can probably use anywhere under my hood. I can do it myself if it's safe. The thing is, is it safe to use this torch anywhere under the hood just like that? Especially on the headers? (well not actually the header itself but the bolts on the old header). Because if I can simply do it myself with a product like the one I just showed you, I'll just buy that torch and do it myself in my own garage. But still, please answer the questions I asked in the last post, it's very important for me.

Thanks.

Do you have to use a special machine that cleans off all the gasket metal from the factory gasket BEFORE putting on the new OBX gasket? Is that really necessary?

There areseveral posts on this forum that say NOT to use the OBX gasket that comes with the header. Do a search. Ithink I remember19Accord97 had a heck of a time with the gaskets. I think hewound up having to take off the header and throw out the OBX gasket and get a better one, then put the header back on again.

Alright, I did the search, and found that people bought gaskets from Pep Boys and Autozone. The thing is, what exactly do I need to ask for, am I asking for the gasket sheet that connects the 4 pieces of the header onto the engine head? Or am I asking for the gasket that connected those 4 pipes to the 2 pieces downpipe, since it is an OBX 4-2-1 Header. Or am I getting both?
