hey everyone just gt my 03 mini s about amonth ago and was tryng to change plugs and two of them are stuck, anyone have any info on how to get them out? thanks

 

Penetrating oil might help. You might also try running the engine and once it's hot, try cracking the plug loose.

When you put them back in, use some anti-sieze compound on the threads. Don't over do it and make sure none of it gets on the insulator or you'll ruin the spark plug.

 

Do not get the engine hot, warm maybe. When the engine is hot you risk the chance of stripping the threads on the aluminum head. Put a little motor oil down in the spark plug tube and let it sit over night and this will work best if the engine is warm not hot to keep the oil thin.. Then you should be able to get them out. When you put new ones in make sure you use anti seize and torque them to 22ftlbs. Good luck

 

I am thinking that a larger wrench may do the trick. Mini plugs are easy to get at so a bigger lever will probably work. And, since the plugs are down a well,it will be hard to break them even if you have a longer extension than necessary.

I can’t see how anything you pour in there will get to the threads and would avoid heat like the plague.

And a bit of anti-seize on the threads, just a drop, is in order on the reinstall.

All of these are good ideas I would get the engine hot and put oil in the recess and let it sit over night. Try a larger wrench and if you can get one to move use a rocking motion to remove meaning unscrew a little then screw it back in a little less and repeat process until plug is out

 

Use a penetrating oil like Liquid Wrench or Jig-a-loo, not WD-40. They are lighter than motor oil and work in better. A warm engine should be easier.
A little tightening and loosening is a good idea.
Don't go all Rambo with a big wrench or you could break the plug and be in real trouble.
