Tractors stored outside and vertical exhaust - opinions/tips

So I just found my ford 3400 3 cyl gas was full of water in the motor. Appears to have come in via the vertical muffler. It does have one of those rain flappers on it. Are they useless longterm outdoors? Its been out all winter and March hit us with hard rains and strong winds.

I've seen tractors with cans or buckets on the pipes, was this why?

As I use it in the woods anyhow, I was thinking of ordering an Oliver side inlet muffler and laying it down alon the hood and putting a turnout on.

Opinions/advice?

Drive it frequently or toss a bucket over it. I've had good luck with just slant cut pipe and starting regularly and mine live outside in wet climate.
 
Look at how the muffler or tailpipe attach to the manifold. I had one unit that the muffler slid down into the manifold and water would follow the muffler down and drain directly into the manifold and from there into a cylinder and on down into the oil pan. The only recourse is to completely cover the engine or put it in a shed.
 
I bet if you look at the pipe where it goes into the muffler you will find a small crack. The way the pipe is setting, I think it is collecting water.
 

Like Rm MN said it depends on how the pipe attaches to the muffler and manifold. You would have to run a hose down a Ford four cyl pipe to get the water into the manifold. The pipe on my 9000 goes directly on the stub out of the turbo, so a little trickle down the pipe would most likely not make it into the turbo. But I am much more careful of the 9000 pipe and I put a can over it if there is a chance of rain.
 
I store at least 12 tractors in my back and side yard year around all with vertical exhaust pipes. When the top of the exhaust pipe is bent like yours the rain cap will leak. I had a limb bend the exhaust on my backhoe when working in the woods. The little loader tractor muffler was cocked and also leaked. The exhaust came straight out sideways and up thru an elbow. The elbow had a hole in it to drain the water out. It still rusted out the manifold but didn't get into the engine in any amount to cause a problem. The rain caps that are on flat do not leak on any of mine that set for a couple years without being started.
 
Thanks guys.

I'd been thinking the flapper needed to be square (the motorcycle muffler has a slight turn out) and I figured I'd have the flap have to hang down.

Realizing now that the counterbalance might be overcompensating at this angle and lifting it enough to allow a good gust to blow it right open.

With my luck I parked it pointing into the wind and it'd gotten held open for the 3 days of storms.
 
like said, the muffler and manifold joint can be a problem with water running down the muffler and seeping in.
And blowing snow can find any crack...anywhere.

Tractors with good joints, I first slip a furnace ductwork round pipe over the muffler all the way down onto the hood, then throw a bucket over the top.

Bad joints, or joints where the muffler fits inside the manifold outlet.....I cut a piece of thin sheetmetal (posted sign works good)...wrap it around the muffler pipe close to the manifold, clamp it, flare it over the manifold joint....umbrella :)

...and on one JD and one Farmall that always seem to get water over/after winter...Parking them in the Fall, muffler gets pulled out, tin can stuffed over the manifold outlet...then a tarp
 
Stored outside? Yeah, don't do it. Water seeps in, condenses inside other areas, starts corrosion that once it pits metal, the pit just keeps on getting deeper and deeper, and eventually cannot be stopped. Paint fades, rust gets a good start, UV sunlight degrades everything, tires rot, sit into the mud..... ... don't do it.
 
Had the same thing happen on an H Farmall continually, even after putting a can over the pipe. I finally figured out there was a leak where the exhaust pipe is threaded into the exhaust manifold. The threads where shot in the manifold.

The proper fix would have been to replace the manifold and pipe, both. But-in the interest of expediency, I ground the rust off of both surfaces and brazed the pipe to the manifold. That cured the problem. Not the perfectionist's solution, but the hood hides it anyway.
 
When I was a kid,we ALWAYS used a Campbell's soup can. When it wasn't on the exhaust,it was slid down over the pulley knob on the Olivers.

FBH44, it sounds like you are offering up money for sheds to everybody, LOL.
 
Soup can, dad was too cheap to buy all those flappers.

The flappers are nice, but for many months sitting outside, drips and drops and strong wind can get some water in past it. Is yours angled,
never seen that before, do thry work at an angle? Water might flow in along the angle?

Part of it depends on how the exhaust pipe attaches to the manifold. If the exhaust pipe fits inside the manifold (vs. outside) as with many Allis tractors water will run down the exhaust pipe and some of it will leak past the joint into the manifold and engine. No engine is safe from water getting inside but ones with the manifold attached inside the manifold are worse.
