So.... in order to get a bit more room in the garage after the move, so I can start welding on the body i figured I'd work on getting the engine up on a stand an off to the side for a little bit... I have the tranny off and wires/FI stripped off and boxed up and have been taking the sheet metal screws off.. I have 4 that are totally seized on... 3 of them at the intake ports and one on the fan shroud.. I've soaked them with pb blaster and all i've managed to do it mangle the slot in the screw a bit..
I'm inclined to just drill out the screws and tap them afterwards... Before I do this, does anyone have any time tested suggestions to get these buggers off?? If not, does anyone know off hand what size the tap / drill I'll need to use ? Thanks ! Mike |

I found that having the actual correct size of screwdriver made a huge difference. The largest size flat-head screwdriver that my local Sears carried was the correct size. It's a big mother, and it fits the screws very well. Lean on that and twist it, and they pop loose right away!

Ice right after mapp torch heat treatment,ice. Please use sound judgement,there will be snap,crackle and pop, and we're not talking about melting ice, (IMG:style_emoticons/default/biggrin.gif) I don't even want to think about drilling,sucess rate, low |
