EGT Probe ?

**DesertSmoker** · #1 (**permalink**) 06-13-2011, 05:56 AM

I installed my Autometer EGT gauge this weekend. It was a lot easier than I expected. One problem the hole that the EGT probe goes through is a little larger than the probe so you can feel exhaust coming through. How can I seal it?

There are two styles. Which one do you have?

1- the probe goes thru the fitting and is locked in place with a set screw.

1- the probe goes thru the fitting and is locked in place with a compression nut. (swagelok)

I have "the probe goes thru the fitting and is locked in place with a set screw".

It should have come with a ceramic washer that is designed to help seal the hole.

I thought so too. I did not find one nor do the installation instructions reference it. Where can I get one?

Mine came with my kit. Maybe try contacting AutoMeter or the dealer you bought the kit from.

Will do. Thanks for the info!

I just called Autometer the ceramic washer is not used in the in fitting with a set screw.

The Autometer tech said a leak can happen and over time soot will build up and plug the leak. Is this an acceptable answer?

I am sure they are correct. If the gaps are small enough, the soot should build up and plug it. You would have thought that their intentional design would have been better than relying on "soot plug"

Agree 100%. If Autometer machined the plug to tighter tolerances this would not be an issue.
