[Supras] Interesting problem...

[Rich Peacock]

I was just surfing Supramania to see if there was something I was 
missing.  I used OEM plugs from Watson and installed them the proper 
depth with a big socket.  I used a bit of sealer too if I remember 
right.  I'm going to reinstall a new OEM plug with red lock tight and 
I've read that green lock tight will wick into the existing plugs to 
help lock them into place.  I'm glad I smelled the coolant right away.  
Shouldn't be any long lasting damage.
