We had our WD out in the field, with a can over the exhaust stack, for a number of years. It was running well when parked; we just didn't have work for it. Now that we have work for it again, we started to get it ready for work and noticed that the can over the exhaust stack had rusted through on top. So at least a little rainwater has almost certainly run down the exhaust stack and into the exhaust manifold and/or cylinders. The only question is how much? We're thinking to pull the exhaust manifold completely off and visually inspect as much as we can, but we're hoping we don't need to tear the engine down completely. Are there any particular recommendations for how to do that inspection, and how to remedy any water pooled in either the cylinders and/or the bottom of the manifold? Thanks in advance....

Remove all the sparkplugs, in case there's water in one or more cylinders, then see if it will turn over.
If it does, the water will be puked out the sparkplug holes, (you can finish drying them out with a compressed air nozzle),then put a little oil in each cylinder and crank it over to lube the cylinders, put the sparkplugs back in (after cleaning or replacing them, as needed.
Loosen the oil drain plug, and note what comes out... water will settle to the bottom and drip out first, if any water drain and change the oil, not a bad thing to do either way, and start it up.
If, with the sparkplugs removed it's stuck tight, at the very least the cylinder head will have to come off.

Dont pull the exhaust manifold just yet. Pull the drain plug as Bob said to check for water. Then see if it is stuck (likely) then pull the plugs if it is. An inspection camera is about $70 at Harbor Freight less 20% coupon and handy item to have in the tool box. Or blow air into the spark plug holes and if you get a bath you should pull the head. If no water comes out you might get lucky and have it come loose by soaking. I have never been sorry that I took a stuck engine apart. Others experiences are different. If stuck do NOT be convinced to drag it around or force it as it will cost you to fix what you break.
As long as the engine is not locked up do as the others say and pull the plug out being sure not to mix up the plugs and plug wires. Then spin it over to make sure there is no water in the cylinders. Then put a table spoon of ATF in them and let ti sit 24 hours with the plugs back in. Then pull the plugs back out and spin it over to clear the ATF and try to get it running. The ATF will free up sticking rings and help clean up any rust in the cylinders
Thanks everyone for your replies. What is ATF? I like the idea of the inspection camera. I was absolutely sick when I saw that the can had rusted through because this is exactly what that was supposed to prevent! We'll get after these suggestions and see what happens. Maybe we'll get lucky and not much got in there and nothing is stuck. Or, maybe the old girl is due for a rebuild. I'm just glad I found it now, months before we need her rather than hours before we need her. Thanks all.
ATF is something you should have on hand if you drive a car since I bet your car has an automatic transmission as in Transmission fluid is ATF. ATF is a very good all around lubricate and I use to to free up rusted nuts and bolts and to free up locking up engines and sticking valves etc etc etc.
Another thing you might think about if either install a exhaust pipe flapper or do a 90 degree angel on the exhaust so rain is a lot less likely to ever get in. I learned decades ago not to depend on the old can trick because you forget them or they rust like yours does. Or when you fire it up you get hit on the head fro ma flying can which did not feel good LOL

Thanks for the additional information. I actually drive a manual transmission '83 Ford pickup, which looks only slightly newer than the WD hahaha, so I feel a little better about not knowing what ATF is. But now that I do I'll be sure to get some. As for the exhaust cap, youbetcha that's also on the "get it soon" list.
As we dig into the WD to figure out how bad it is, I'll probably be posting additional "what do I do now" questions. As always, you folks are the first ones we turn to when something comes up like this. Thanks again for all your help.

Something else to do when you get the ATF after putting some in the cylinders pour some down the exhaust pipe. That way it will get to the exhaust valve to help free any of them up that maybe sticking some.
As for what you drive good for you I see way to many people now days that cannot drive any thing but a car/truck with an automatic in them. That is all I drive and my car has a what should be a 5 speed but 3rd and 4th gear went AWOL years ago and I just drive it with 3 working gears and have for over 10K miles
