What type of thread sealant?

wildfox65 · Nov 10, 2015

I want to install a new main oilier pipe to the water hopper on this Economy engine. There is a small channel on the inside of the pipe threads. See pic. What type of thread sealant should I use? I do not know yet if this channel in the threaded opening of the hopper will be a problem. Groove is on the right hand side of the threaded opening, closest to the near wall of hopper. Would like to use a sealant that is thick in nature.

Sorry, I do not know how to remove the extra's pictures.
Thanks

Since those threads look like a leak waiting to happen, I would use a little epoxy, such as JB Weld on the male threads.

While that may make removal in the future (IF ever needed) a bit more difficult, it would beat the heck out of coolant leaking out of the water jacket and into the bore area.

When I received this engine, the water hopper had a pipe plug in that location. I am not sure why there was a plug in there and not a oilier. I am going to install a oilier to the cylinder. I do have that epoxy on hand. Thanks for the suggestion.

I can't argue that it would work just fine, and I don't get to say this very often, but I think the JB Weld is overkill in this case. I would silicone the male thread, wipe off any excess and move on.

I use rector seal number 5, you can get it at lowes or any hardware store that sells pluming supplies. The bottle recomends only putting it on the male threads but if your worried about a leak I usually put it on male and female ends. If its a serious doubt about if that would hold back any leak then you can wrap some teflon tape around male end then put rector seal on both male and female ends.

This process hasn't let me down yet hope it helps you make a decision on how to fix your issue.

Chase the threads regardless of whatever you use. I have been using Gasiola now for a few years. I use it on hydraulics, fuel, and oil lines. So far, it has been an excellent product. I too agree that JB Weld is a bit much (but it will work). Also consider that you want to be able to remove the oil tube at some point in time (usually when you least expect it), so JB Weld would make that a wee bit problematic......IMHO.
