storage oil (coating)

what do you guys use to protect engine parts that are going to be stored for long periods?
I have tried storage oil that is used on water craft and such. Still my heads rusted. Stored in a dry, but not climate controlled building. Humidity is my biggest problem I think.

Thanks Dave

I store mine in Phoenix, never had anything rust if it was inside. Hell, they barely rust if you leave them in the yard.

I just coat them heavily with Liquid Wrench on castings, or grease on machined surfaces, & bag 'em in head/crank bags. I have the same climate as you. Seems to work OK as long as they don't sit directly on concrete.

i will try the storage bags. I have coated them with liquid wrench and put them on a 2x6 board on the concrete and they rusted. The bags might do the trick. I have a bunch of old Y-block & FE stuff I need to store. trying to get shop organized.

Thanks

Good thick storage or garbage bags are good. I have also had good luck with using the shop vac to suck all the air out of the bag too.

Dave I will check at work and see what it is called but we get a Rust inhibitor it comes in a aerosol can and works rather well, and if I remember we also had some stuff you add to water and spray it on with a garden sprayer that worked also....

Boe-shield works very well too...probably similar to what Randy is referring too...hard to find locally, though. Boeing invented it for aircraft parts & tooling though I believe another company makes it now. http://www.boeshield.com/ Sears sometimes will have it locally.

Bill added something I forgot...you need to either get most of the air out, or just leave the bag completely open for airflow. If humid air is trapped inside you just get condensation over & over again. I don't like trash bags, though, because they seem to be water-permeable, and they break down with sunlight exposure. I just buy crank/head bags or block bags from the machinist which are either 3 or 4 mil. You can buy 'em in bulk, but I don't need 100 head bags....or, an excuse to buy 100 cylinder heads.

I've also made my own "bags" from 3 mil plastic, for weird shapes or large objects, and sealed them as best I could with a line of caulk, and repeatedly folding the seams, like 4-5 times over while the caulk is curing, then stapling them. Pain in the arse.

In Newfoundland you can hear your car rust in the driveway I coat everything in axle grease... inside and out. It's a pain in the butt to clean again though.

awhile ago I bought some h beam rods that were new... I was to lazy to go out in the garage and get the WD-40. so I coated the big and small ends with vegetable oil, and put them each in a bag and put them away... I just got them back out to look at them 2-3 months later and the oil has dried into a hard coating, completely sealing the bearing surfaces... have I stumbled onto something?

CRC Marine engine fogging spray

Regular Hydrolic fluid works great I had a older guy at work tell me about hydro fluid.

A guy that built engines for a long time told me to mix a quart of oil (10w-30 pennzoil, its what I had)with a bottle of STP oil treatment and use a paintbrush to put on the parts. I have a C9 block thats been on an engine stand for about 4 yrs(sad I know) with this stuff on it and there is no sign of rust anywhere, even the freshly bored cylinder walls. I just covered it with a regular black plastic garbage bag. It cleans off really easily with just about anything. Actually I took the bag off about 2 months ago and this mixture has kinda cured to something that reminds me of cosmoline. The building I keep it in is really damp, so yes it does work. Nothing exotic and it works.

how about just spraying it down with Cosmoline

Yes but where can you get it ??

I've had excellent success using Corrosion X HD coating on parts. Complete long term protection, and yet is quite easily cleaned off with a little solvent.

WD40 and Trans fluid about 50/50 in a spray bottle and keep the "Good" Stuff in Heated storage.
