Never did this but noticed someone ask on a different forum which got me thinking(not good). Does anyone who like me lives where it gets cold in the winter fog the engine? Would be interested in pros/cons if there are any. Thanks
Fogging the diesel for winter?

Diesel is an oil.
Hummmmm at least it ust'a be. But maybe today it's something differant.. So my oPYnion would be to fog it, what can it hurt? ooppps thinking gets me into trouble.

Don, you're a regular here
scroll down about ten threads - sound familiar? FOG what??? Would someone please explain what this means, please?

fogging is
coating the cylinders of an engine with oil so they don't rust during layup. IMHO there is not going to be that much water in the cylinders anyway once I drain the muffler. And you shut down the engine when it was hot so it is going to be dry to start with. The open exhaust valve on one of the cylinders can let the wet air from the muffler into the cylinder but that is one of the reasons for draining it.

I think. Seems the consensus is diesel is an oil... so is gasoline by that logic. I guess the conventional wisdom is that it isn't necessary which is comforting since virtually all powerboaters around me with diesels fog their engines. Stu - what thread?

Argghhh
Apparently the chemists and chemical engineers haven't caught on to this thread yet. In any case, it sure is depressing to see the winterization debates picking up already.

Don, this one:

That gets me ALL of what's going on. Some folks post subjects in "their boat size" categories that apply to many others. That's why I prefer to see them all.

While in a Fog, and trying to winterize a diesel
all you have to worry about are the cooling system, electrical system (batteries), fuel system (bleed something, fill the fuel half way or better and add biocide and stabilizer?), and oil system. Am I missing anything? I do not mean to lubricate this thread but I suppose that is what I am doing.

A wintrization hint:
When you lay-up for the winter, loosen the engine belts to remove belt pressure from the alternator, water pump, raw water pump. Like a car that's laid up for a certain amount of time the pressures can stretch belts or pull the wrong way on a pump bearing which will force them to eventually fail. I lost an engine water pump and about 6-8 hours of labor three years ago because of this. Problems didn't materialize until I commissioned in the spring.

Nope
Tape the exhaust thru-hull and air intake to keep moisture out. Don't forget to remove in the spring!

not needed but, if you insist....
they make special fogging oils but you can also us WD-40. Remove the air filter and spray WD-40 into the engine as it's running for 15 seconds and stop the engine. Reinstall the air filter. easy. You can also crank the engine with the compression released and spray the WD-40.

Pauls advice is important .......
I quasi-remove (greatly loosen but leave in place) my belts and spray 'Boeshield' on the belt-polished sheeve surfaces to prevent the inevitable 'rust blooms' that occur over the winter. Most sheeves will rust over the winter especially in the areas where the belts are in contact with the sheeves. On Yanmars this is a very common problem .. and the subsequent roughness in the vee grooves leads to premature belt failure later on.

Don Casey says
For what it's worth, I found this in the Don Casey library at boatus.com "Fog cylinders--gasoline engines only Remove the spark plugs and spray fogging oil into the holes. "Bump" the starter to spread the oil on the cylinder walls. Regap or replace plugs, as required, and reinstall. Fog intake--diesel engines only Spray fogging oil into the intake manifold and turn the engine over slowly by hand to draw the oil into the cylinders and spread it. Do not use the starter, even with the stop control pulled out; the engine can start on the fogging oil." It seems lots of folks here respect Dons opinion.

Your link is to a Catalina specific site. Don has a Hunter. I doubt he spends time looking at a site that is supposed to be Catalina specific. I know I don't.

Thanks, Richard, but Don's post
showed up on the 24 hr Activity, which is where I caught it, so??? Don's a valuable contributor and his input is very helpful, and I'm glad I "get" his material on our Catalina board. Don, how does that work for you?
