Ok, then are you going to get back to getting the lifter rod out? FYI, I have never had a problem with lighting motor oil when heating with any kind of torch. You might want to clean off the immediate area. Not to be flippant, but I really don't think it has sunk in that removing the nut is not going to make that rod any more accessible to you than it is now, unless you plan to break the end of the shaft off to get the nut off. Heck, then you can probably use a tow chain to pull it out.
