Oil for a Slant Six that's been sitting a long time

The 360 sitting in my carport was naturally locked from sitting for 3 years. I added diesel to the crankcase and let it sit for 2-3 months.I used a priming tool and ran the oil pump for a solid 2-3 minutes. Then I carefully turned it over by hand. It broke free easily,so I spent a couple hours working the motor back and forth,pulled the valve covers and made sure there was lube getting to the top end. Filled the cylinders with oil and then drained the crankcase of it's nasty deisel/oil mix.

So thats what I would do. Dont run the motor,too much potential for damage. Simply fill it with diesel and work it back and forth by hand.Use the priming tool. You could heat the deisel before dumping it in.
