anyone ever had one?

if so, what kind of luck did you have with tapping it??

i had to ram one back in there to get the car back up to CO after a futile attempt at changing the plugs in TX right before i had to report back. so now theres the front leading plug in there crooked. seemed like it was firing fine for a while, but more and more recently it feels like its causing the others to foul out....HUGE loss of high end power.

thanks for any help/advice

Nic,

When you retap it you are going to have to be very careful not to get metal into the rotor housing. I'm talking about clean it out before you start, then like one turn, pull out tap, clean, again and again. You will also probably have to come from the underside to do it right. I can get the tap size for you tomorrow .. but I think it is 14 X 1.5 ... like I said I'll check tomorrow.

Prevention is the key word!
1) Always use a very good antiseize everytime the plugs are re-installed.
2) Start them by hand to insure a proper start.
3) Remove plugs at lease twice a year to prevent binding/sticking due to heat weld.
4) Do not torque them more than 10ft lbs.


I have noticed that even with new plugs and antiseize, if plugs are left in aluminum for a long time; they will still start to bind/ heat weld. Thus removal, relube, and re-install periodically is a must. I have never had any plug problems in my 32 years of aluminum engine cars because of following these rules.
