Sparking plug torque

PostPost by: StressCraxx » Wed Oct 19, 2011 4:30 am

A drop of oil on the threads of each plug from the dipstick. Thread plugs in with fingers, torque to 20 lbs/ft. Torque specs from the Machinist's handbook tables are for oil lubricated threads. I have never stripped a spark plug hole in 48 years of car repair.

Never-seeze often seems to wind up where it should not be. Told my engine builder he wasn't going to get another flagon of rum if he ever did that again.
There is no cure for Lotus, only treatment.

I agree..

For the first time ever! I used a torque wrench on the plugs in the Elan, and lo and behold it sure felt way too tight, so I stopped short of full click on some. Even checked two torque wrenches against eachother. I am afraid to remove them now :( .
I was debating posting to see if the manual was incorrect.
Never had a plug leak, break, or seize when I did them by feel; back to the feel method for me!

re the anit sieze - Copper and aluminum are on opposite ends of the galvanic series, I realise not in salt water but, hmm should Cu be used?; notwithstanding the copper head gasket surface :?
