				Motor storage?
			 
			
			How long would I be able to store the motor of my 300CE without gaskets (head) and such going bad. Would I have to do anything special for prep before I store it? Thanks in advance?

			I'd put this in technical for better answers. I've never had headgaskets go bad from sitting. I've had some water or seals seep a little from drying out. I use Stabil Fogging oil to shoot into the cylinders to prevent them from rusting while it sits. When I go to re-start a motor that has been sitting I pull the valve cover and pour oil on the cams and down the timing chain.

			Also turn the motor over by hand (i used a long socket wrench) every once-in-a-while to make sure all is moving correctly as well.

			The critical issue in all cases is keeping it dry = no condensation.. Long Term Engine Storage http://www.eng-tips.com/viewthread.cfm?qid=297776&page=1 .

			What is considered "long term" engine storage?

				Hmm
			 
			
			That is a tough question. My rule of thumb is: * 6 months to a year is short term. * Anything over one year = long term. |
