My car is in storage now. Does anyone know of a way to "fog" the cyclinders thru the spark plug hole to get a coating on the cylinder walls? After a long time in storage, the oil on the cylinder walls eventually runs off leaving them unprotected against damage from moisture. I have heard of using WD40 and also of just squirting motor oil in the cylinders thru the spark plug hole.

Make sure if you use the WD40, that you hang onto the little plastic tube that goes into the nozzle. I found out the hard way that they come off!!!

I have used a squirt can of oil before.I now use Kawasaki fogging oil in a aresol can for watercraft.

Good old Marvel Mystery Oil! (MMO!!!!)........

It's good for this!!

Just take an oil can and squirt several shots in each sparkplug hole and roll her over a couple of times and you should be good to go!!

Thanks-never thought of the Marvel Mystery oil.

I have never fogged an automobile engine that sat over winter. Maybe I am old school, but I have never had a problem to warrant fogging. I guess if it makes you feel better, you can do it, but if it is just sitting for 3-6 months, I dont see a reason for it. Of course this is my 45 year old minds opinion :D

Don't use WD-40. It's the most over used "miracle" stuff on the planet. It's a water disperser and only a fair lubricant and protector. Use fogging oil if you think you need to use anything. I've never done anything to protect one over the winter and haven't had any problems.

That's what I did. The stuff is amazing. But I coated the walls before I put the heads on because I knew it wouldn't be run for a long time. Then I lashed the valves so the walls and rings got coated together. MMO doesn't evaporate or run off like sticker-remover WD-40.
You could also use PB Blaster and spray it in the cylinders. It's a very good lube.
I haven't purchased WD-40 in years.

If an engine's just going to sit for the Winter, it's not a big deal. If it's in a garage (dry) and in the car, you shouldn't have to worry about moisture inside the engine.

My car does not sit in a climate controlled atmosphere or inside a bag with dessecant. It is in a garage, with a car cover, and without heat. The car has now sat for about 2 years while I work on it which is not 24-7 (wish it was). I had a couple of minor surgeries that took me out of commission for awhile. My original question was based on long term storage. I have already used the WD40 and it was a pain in the butt to even get a squirt off into the cylinder. I did not really think WD40 was the best for this either but several people advised me to go this way and I never thought of the MMO. I plan to do the MMO this week (I'm sure the WD40 has probably run off or dried up by now?).

Just use a marine oil fogger, it will be fine. Any and all of the above mentioned will be fine. I have opened up engines that have sat for years and the cylinders were still good.

I second he MMO and if I think I will not be driving in while, I will release valve spring pressure from valves that are open. This will also close off open exhaust valves to keep the roaches out and save valve springs. Course I am old school too.

He, He!!

Keep the "roaches out", I love it!!

Around here it's the darned "mud-dauber wasps" in the summer time!!
