Plug egr hole on stock exhaust manifold

[letitsnow]

By accident I found out tonight that the threaded part of an old 2" trailer ball threads into the hole. I cut the threads off of the ball, threaded it into the hole, then tightened down the nut to lock it in place.

The ball was junk, and for somebody as cheap as I am, this is WINNING!!!

Any idea what the threads are, maybe 3/4"-10?

How do you find that out accidentally?

Always had the need to see if something will fit in the hole when I see one - dunno?

I am not sure. I ordered a new exhaust manifold and it had a new egr fitting included. My neighbor picked it up while telling me stories and starting threading a nut onto the fitting. The nut fit. It was off of the ball that I had just removed to scrap.

Wild Guess: the threads in the manifold are Metric. The hitch-ball has SAE threads that are "Kinda Close".

Metric-to-SAE misthreading is fairly common. Guys do it all the time when they buy brass inverted-flare seats and pound them into Saganaw steering gears, to convert a newer steering gear that used O-ring seals to fit an older vehicle that has inverted-flare hoses. The O-ring boxes are Metric threads, and the Inverted Flare nuts are SAE. They kinda fit together.
