EGR tube block-off solution for the 4.2L

There are alot of threads asking how to block off the hole in the exhaust manifold if you remove the EGR tube. Solutions were pretty hard to come by aside from welding it shut. I thought i would share my findings to make it easier for anyone else facing this canundrum.

The oil drain plug for late model dodge trucks fit perfectly. Autozone carried it for $4.99. The box says its M22x1.5 size and uses the end of a 3/8" drive ratchet to tighten it. I put a little threadlocker on the threads then spread exhaust putty around the outside to make sure it doesnt work loose. So far (its been a week) absolutely no problems with it.

I hope this saves someone else the headache of trying to find something to fit.

Any idea what year dodge it comes from. I made a plate out of 3/8 Aluminum and it 100% blew apart in less then a week. So this would be an amazing fix. I tried everything from a plate to brazing to that exhaust putty

Not sure why you would remove the EGR. It does not hurt performance and actually serves to cool combustion temperature.

There are no years listed on the packaging, it simply said dodge trucks. It was something carried on the shelf at the local autozone though. Should be easy to find, just compare the size. Like i said, it listed it as M22x1.5

While I totally agree with jay, I thank you for posting this info, it should be a help to those that are in search of this fix.

It's a hard thing to come by. I looked everywhere. Mine has no emissions in mass so as longs as the egr is there it doesn't matter. It's annoying tho. The exhaust manifold I bought new stripped my 02 sensor. So I had to bolt that up to. I could have gotten a new one but I wasnt gonna pull it back off.
