I'll finally get to my EGT gauge installed this weekend. I will be drilling into the manifold, and was wondering if anyone has used some type of sealer on the probe treads...(autometer gauge) I will also use the drill & grease method, even maybe engine idle to keep the metal shaving out..thanks

I didnt, the instructions didnt call for it either. Dont have any leaks or problems, dont know how well teflon would hold up around 1100 degrees either.

Ahh no thread seale,not sure it would last very long before it went up in smoke...

I used anti-seize on mine.

same here. All I used was copper antisieze (higher temp raiting then nickle) havnt had any leak on either truck and I did the 1 truck twice when I replaced the manifold.

Yup, anti-seize and nothing else. Never had a problem taking one out either.

I just did mine yesterday, and didn't think it would be a good idea for thread sealer. It's a pipe thread, so the hole actually ends up being tapered, resulting in a good seal.

I drilled and tapped mine with greased bits and with the engine idling. Wear safetly glasses and gloves (it gets a little warm, but not bad) and take your time. Piece of cake.
