Seized sprk plug fix
Hopefully this wasn't covered recently on here. My 88 has had #2 plug seized tight since the day I puchased the car. I changed the rest but this one would not move even the slightest bit. I have tried everything from "liquid wrench" to "PB blaster". Soaked and soaked and nothing. I had givin into the fact that I would guts it and if it twisted or pulled the threads I would just end up having to pull the head to do the needed repairs. One last thing I told to try was turpentine. Yes turpentine. I still can't believe it but after three applications in about 45 minutes I put a wrench to it and it turned. I worked it tenderly out and had NO damage to anything. Who would a guessed. Just wanted to pass this along if it hasn't already been mentioned on here.

Unbelievable , turpentine must have many uses. I have seen people use it on cuts to make them heal in a couple days, I have personally seen it work for this purpose.. It must be a wonder fluid..When you put the new plugs in give them a smear of antiseize so they don't stick again..

One of the drawbacks of plugs that last for 100,000 miles or more; by the time you really need to change them, they're frozen stuck and you're pulling the heads! Heat sometimes works better than anything else. Run the poop out of it and then try (without burning your hands!). Otherwise, even the old tech in our C4's keeps the plugs happy for a long time and absent an obvious misfire, you might just check fuel delivery first. If it's dead on, you get nothing other than a shot at stripping some threads.

Never tried that, wonder if it would work any where else? Also got to wonder if the previous Liquid Wrench and PB Blaster didn't have something to do with it. No matter it worked and that is what counts.

The same idea is worth mentioning for tires there is no sense buying tires that will go 75000 miles if you only drive 2000 a year they will be rotted before you get to the 75000 miles. Better to buy some softer cheaper ones that wear out in 25000 miles or less and change them before they dry rot.
