Glow Plug Question

[thebigarniedog]

Any problem with using teflon tape on the glow plug threads?

I don't think teflon makes a very good conductor. You may have grounding problems getting a connection through the threads. It also lubricates the threads, so torque will be way off spec.

Out of curiosity, why?

There is a taper on the GP which seals combustion, not the threads. As above, the gp may have issues with proper grounding if the threads are insulated with Teflon tape.

I was asked the question, thought about it, and did not have a satisfactory answer ...... so I posted it hero. There should not be a grounding issue, since there will still be contact.

I wasn't questioning your question...ing (thats a funny saying), I was just wondering if you were trying to fix something I guess. Like someone a glowplug hole/thread cracked or expanded and you were wanting to seal it up or something.

I always use Anti-Seize and have never had a problem with conductivity or removal.

Teflon is good to about 500°F working temp.

It would still ground at the seat area unless that were taped too. Then you'd be relying on it being squeezed out.

The asker prolly has a leaker he's trying to repair.

He should have questioned the questioner.
