hey everyone just got my 03 mini s about a month ago. well last week I was goin to change the spark plugs on it since it has 127,000, I got two out fine the other two are stuck in there. anyone have any info on how to get them out with out breaking? thanks

 

You should not need alot of torque to get the plugs loose. If you are using a standard 3/8" ratchet drive, consider a long-handled 3/8" driver, or go to a 1/2" driver with a size adapter if necessary. The increase in mass will give you more leverage. You can even slide a piece of pipe onto the end of the driver (or even use a torque wrench if you have to).

As for tightness in general, make sure you are changing your spark plugs when the engine is cold. Never do it with a hot engine. If that is not possible, at least give the engine an hour to cool down (more on hot summer days). If you are still having issues, get a can of PB Blaster and spray a small amount around the base of the plugs inside the tubes. Let them sit for 10-15 minutes. When you break them loose, use a rolled-up paper towel and "dab" it into the threads of the head. It's not going to hurt if some goes into the combustion chambers, but at least try to clean it up as best you can.
