how do you guys break that bolt off on the drivers sead head. the one that hooks the smog tube up to the back of the head? i think its a 9/16. but i keep pushing up on it after soaking in wd-40 and nothing. its a tight fit to begin with. i wish i had a 2 foot 9/16 wrench
If you need more leverage, either get a pipe just bigger than the wrench and slip it over the handle, or get a bigger wrench and slips the box end over the handle and work it so you can use it for extra leverage. The pipe would work better, but not everone has one laying around. Either way, at this point it's probably best to put something on top of your fender and be very careful -- it will probably take a lot to break it loose and you don't want to chop your fender with a pipe!
