Gary Lewis Posted February 28, 2018 Author Share Posted February 28, 2018 Why even think about removal? If you do want to take it out, just use a brass plug. Bill - Hadn't thought about the manifolds glowing red, but they do. I've seen it. And, that's above the temp that Teflon tape melts - 500F. Ok, bad idea. Thanks. Jim - Maybe I'll use a brass plug. From what I see brass melts at 1700ish, and red on a manifold should start around 900 degrees. Surely a manifold won't get to 1700? Link to comment Share on other sites More sharing options...

I use brass nuts to hold my head pipe flanges on the manifold studs. (And I realize even the passenger side is farther from the port than this plug) I've never had a problem.

JayFinAZ Posted March 1, 2018 Share Posted March 1, 2018 Good point. And the joint was brazed, so a brass plug should be fine. Thanks. Drained the T18 and refilled with synthetic gear oil. Shifts quite smoothly now. I imagine the old stuff was pretty old. Link to comment Share on other sites More sharing options...

Ford F834 Posted March 1, 2018 Share Posted March 1, 2018 Drained the T18 and refilled with synthetic gear oil. Shifts quite smoothly now. I imagine the old stuff was pretty old. I'd be interested to know what you used also. When I did the 4x4 conversion on mine I changed the fluid and now it shifts poorly compared to before. I don't remember what I used, but I know it said synthetic. I hear it more than before, but it was bolted to a straight piped diesel before so... but it definitely has to be speed matched to shift now, and can be really cranky in the cold. Sometimes hard to get in reverse also. It used to shift like butter and was the smoothest truck transmission I've ever had. I'm hoping a fluid change will get it back to what it was like when I pulled it out of the diesel. Link to comment Share on other sites More sharing options...

I bought 4 and used a little over 3. The oil is clear, btw. Not brown or yellow, clear, like Karo syrup :) I can't hear anything different, but my ears work very poorly, and there is so much noise from the tires there is no way for me o know if it got quieter as well.
