Spark plugs Loosening up hey guys, I need some help.
I have NGK Tr55's, when I first tightened them I followed the instructions from the box, and I've had 3 plugs all from the driver's side head that have loosened up over these past few months. Now, I keep re tightened them but they seem loose up after a couple of weeks. any one have any input? it would be appreciated
TIA

Remove the plugs and chase the treads in the head carefully (put grease on the chase to pick up metal particles). Apply anti-seize to the spark plug threads and re-install.

be very careful about the chase. these threads are really important so make sure you do it right. not saying you cant do it, just saying be careful so you don't have more problems after you're done.

Thank you guys, but I might use this as an excuse to go H&C! 
I got to be careful though because one good compression stroke, can blow number 1 right out, If I dont check it often.
