Late A manifold / pipe connector leak

pbb · Feb 13, 2020

I got a leak where the pipe connects to the manifold. What is everyone using to seal the pipe up? Thought about trying to find a donut gasket that would fit. I tried using sand paper on both ends to clean the surfaces up but it didn't help. Thanks.

Does it not have an 'O' ring ? We are talking about the water pipe - yes ?

The correct O-ring is most likely still available from DEERE.

However, the tube may be rust pitted beyond use.

Some guys have been able to find exhaust tubing at a muffler shop that will replace water pipes and some models, or, likely a reproduction tube can be found though a restoration parts supplier, if it comes to that.

If you're talking about the upper water pipe, it's brazed to the manifold. More than likely there's a rust hole in the pipe. There's no gasket or donut between the pipe and manifold.

YT parts has the pipe you need. It's also available elsewhere for less.

If you decide to replace the pipe post back for some info on how to do it.

I interpret this to mean the exhaust pipe fitting to the exhaust manifold. If true, I would tighten the clamp lightly, heat the pipe close to the manifold and tighten slowly. Might have to heat it more than once. Tighten slowly,gently. You don't want to break an ear off of the manifold.

If it is the exhaust I have been using the doughnut gasket from a 350 chevy motor. It fits right in and covers the inside of the manifold and the little flange of the pipe to the muffler. If it the water pipe you can clean it up real good and with the coolant out I have j b weld the hole. Let us know for sure witch pipe is it and we well help.

At a NAPA store or any good auto parts store you can get muffler cement. Clean up the manifold and the pipe flange coat both surfaces with cement,bolt it back together and you are ready to go. I don't know what they were thinking when they made that arrangement because you will never seal two hard surfaces.
