Best Way to Plug EGT bung

[98gsspy]

What the title says. I read that bolts and lock washers can back out. Does anyone make a plug for the EGT? Thanks

I used to work at a muffler shop and i would see a lot of cars with missing exhuast manifold bolts or bolts that were hard to remove...so it can go either way. What i would do is plug it with a bolt and put locktite..that should do the trick.

mine is tapped with 1/8 pipe . you can go to the hardware store and get 1/8 pipe plug.buy a steel plug, not brass

Actually brass plugs are better to use if you plan on reusing the bung someday. Brass is self lubricating and won't sieze up in the hole as easily. You might have 1/8 pipe or 1/4 pipe, it just depends. Take your EGT probe to a autoparts store and they can hook you up.

I would use steel than brass because brass has melting point of 1600-1700*f and steel has a melting point of 2600*f. I would use brass for hot water.That is why o2 sensors are made of steel.
