If the threads were ok second time I'd say you are good to go. They should seal up just fine.beemer100 said:Well I just replaced my spark plugs with the NGK plugs from Beemerboneyard and since they were not the Bosch plugs, I coated them with anti-seize. I failed to read in the manual until after I had already done the wrenching down . . . but I torqued them to the full 20 NM. The book indicates to reduce torque value by half ( ie 10 NM) when using a lubricant on threads.
Do you believe I now have a problem with the threads? How can I tell if I did any damage? I have since loosened the plugs and installed them at the half value indicated.
Also, should I buy new plugs due to the plug gasket having been compressed too much?
