Well a buddy of mine from school brought by his 91 Tbird(lx not sc) and it has 187K on it. Well I was to just doing some basic matinence on it for him, till I went to swap plugs...the plug "boots" were melted to the plug, so i spent close to an hour getting all the boots and wires off in pieces and slowly started noticing that all the sparkplug tips(cant think of the name, where the boot goes over and where it "plugs" in) were all rusty. after the melted boots/wires, and the rusty plugs I asked him when was the last time the plugs were changed. His reply was, We have never changed it since my mom owned the car(got it witha round 20k on it) so now, I was like this is going to be a nightmare and started trying to take the plugs out....not a single one would budge, so I got some penitrating lube sprayed alot on each one, let it sit for an hour, then tried again. I even tryed using a cheater bar...close to 3foot long....would not budge. So I take and put the new wires on, then drive the car and get it warmed up(hoping it would make it easier to get plugs out) no dice....So does anyone have any advice on how to get these plugs out? Its a pain in the *** to get to them because of the angle, let alone that I cant break them loose...ANY help would be apprecated.

If I was in your shoes I would let him try to remove them. Or at least make sure he is aware of the negative possibilities. Friend or not when it comes to money people get shady and removing the heads is $$$.

Im against the idea of air tools to remove the plugs but that is your call. I would try letting some PB blaster sit overnight and use a 5' steel bar over wrench to get some leverage. You only need to loosen them with it.

I have the same problem. I was afraid I was going to snap the plugs in half but I pushed/pulled on and got the 4/5/6 slots (the ones on the driver side). I am stuck on the passenger side ones though. There isnt enough room to work with and I cant get a good position to loosen it. :(

The last time I was at pep boys I asked their service center how much it would cost them to do the 3 plugs. They put my car into the computer and said $100 for the labor. :mad: I figure I would be better off just buying the proper tools to do it and get more out of it.

Would a power rachet work (not air power)? I saw one by black and decker that is like the power screw drivers they have. It would be much more cost effective to get that, but im not sure if it has the necessary power. :(

Ive tried all the above things, tried air tools, Electric impact gun, breaker bars, took a 6 foot length of steel pipe over the end of the wrentch and i put my full body weight on it...would not budge...I guess its time for him to figure out what to do now...Thanks for all the suggestions though guys, jsut wish I could have got those out for him, its a miracle that it still even runs...

I've broken 3/8" drive stuff what that kind of leverage. But my full body weight probably has a bit on yours. :D

That kind of leverage should have done something.

I know this is probably an obvious.... but are you positive your turning the rachet the right way? If all else fails go to a mechanic... pepboys quoted me $100 to change them.

Your post got me a little concerned... not sure if I could do my 1/2/3 plugs now :( . Any suggestions on how to get a good grasp on those? Its hard to lean into them or anything since your pushing them into the windshield direction and its deep inside the engine bay

Yeah, I'm sure I was turning it(well trying to turn) the right way. But I finially tried again tonight and got them out.

Basicially I was thinking, Get more room to work. So I pulled the hood off, and the ac compressor thing, so I had a nice amount of room. took the socket a u jount, breaker bar, and then grabbed this wierd looking tool I found in the garage...no clue what it is. its like a crowbar, with a box end wrench on the other side...its roughly 5 foot long, and weights around 10lbs...hard to explain it...my dad didnt even know waht it was, it was something of my grandfathers...but neways, slipped the end over the breakerbar, then I basicially used my weight and slowly pushed into the bar....I will say, from all the high milage, poorly taken care of cars, this must have been the worst...and at school, we get some pretty horribal cars in there....


as to why it worked today...no clue, Who knows, I could have been doing something stupid, but owell. I will say, though, after I got the plugs out/changed, I put on a nice amount of antiseze on teh plugs :)

Probaly created enought fatigue in the corrosion.

i was also going to suggest trying to tighten them a little first, because often times that can break the corrosion on it.

Try it cold.

Instead of heating it up, try cooling it down. the plugs themselves. Go to an electronic repair store and get some "Super Freeze" and douse them. You could hypothetically use freon but that would be frowned upon by the guy over there hugging a tree.
