Storing Engine Block

Can anyone give me tips on storing a engine block. Looking to keep the corrosion to a minimum or none. What are the main areas that are a concern, and what have others done. any special products other than just oil everything down.

Re: Storing Engine Block

Chris,
Has it been run or freshly machined ? How long are you going to store it ? Where are you going to store it, out in a shed or in a heated garage ? I have blocks that have been stored for 10 years and I have done nothing special but they are inside and the temperature does not vary a whole lot. Plastic bags seem to make things worse as they hold moisture. Guys smear the cylinders with grease and invariably moisture gets behind the grease and makes things worse. Let me know some more details and I will give you my suggestions.

yes it was running when I pulled it down about 5 months ago. Timeframe for storing is unknown, just keeping this 502 block around as a spare. could be long period of time before getting used again. It will be stored in my garage, usually heated to 75F year round, even through winter.

X2 on not using a plastic bag with fluctuating temps. Kept my 454 short block in a bag and oiled. Every 6 months I would rotate it and again wipe down the cylinders. Non-heated garage but I would use a kerosene heater most winter weekends. Probably would warm up 20 degrees or so.

Fast forward 10 years and all my parts are at the machine shop. I get a call that my cylinder walls are shot. It was not a marine block but when they tried honing and then boring the block this corrosion starting appearing. I will try to find a pic.

Got another block and it’s now built and in the car.

Chris,
If that is the case then just shove it under the bench and put a blanket over it to keep the dirt out and it will be fine. I have a Mercruiser 502 short block sitting under my assembly bench that has been there for at least three years and still looks exactly like it did when I put it there except for the dust on it

Re: Storing Engine Block

Coat the machined surfaces with 140 weight diff fluid. The rest with spray oil and bag it. Have a peek every few months.

Re: Storing Engine Block

Oil it and bag it up. There are plastig bags with corrosion inhibitor(VCI).
We use them at work to ship untreated parts overseas.

Re: Storing Engine Block

Cosomoline...Uncle Sam used it for long term storage of rifles, etc. FWIW ...I bought a bunch of Kellogs KEL 57300 "Black Oil Spray" for long term storage of machined parts over 15 yrs ago (or more), parts are still like the day they were done. Gooey, slimy, sticks to anything, everything only way to remove it is wipe it off or gasoline or kerosene or fuel oil as a solvent. Their ad states "goes on like a 10W oil, dries to a 600W grease". Prices vary from $8.91 to 36.70 for a spray can, True Value may be your best price, either on line or if your localTrue Value dealer has a "deal". Research it, if it's what you want check everyones price. I still have about a case and a half left from my original purchase, good stuff for long term storage.

The only problem with any of that type of stuff is that your machine shop will kill you when you bring it to them and they have to get it off

Re: Storing Engine Block

I was waiting to hear Bill K's reply as he is a professional builder. I would have sprayed it down with WD40.

Re: Storing Engine Block

Lubriplate open gear lube L0152-03. Have a 66 L79 that's been in storage for more than 15 years on a stand in a pole barn. Heads are off. I spray them down every 6 months and roll the crank a few revolutions and throw the cover back on them. It still looks fine. I also like cosmoline for some parts.
Place I work at had some car parts (One of a kind type) from the early 20's dipped in cosmoline stored in a large crate in a quonset hut. A Eng. was assigned to clean the hut out and didn't know what the parts were or what they were for...he through them out. Owner of the company made a visit a week later because he caught wind of the hut being clean out and wanted to make sure his grandfathers crate was still there.....Needless to say the Eng. didn't work there any longer after the visit. For very long storage cosmoline is the best.

Re: Storing Engine Block

They have some expensive oil often called pickle or knuckle oil that"s often used for aviation engine storage, we have used it to preserve engines out in the gulf of mexico and it works great, but if you can't find or afford it an other good method is to fill it up with diesel (the red farm diesel), fill everything up to the brim. Can verify on the diesel method, we had an engine sitting out in that salt for almost ten years and there was no internal damage, can't say the same for the outside of the engine though. Also when we have engine parts coated in Cosomoline we usually soak them in diesel to get that stuff off.
