A friend of mine just gave me his 1980 scout11. Drove approximately 10 miles after sitting up for 6 years, ran fine then next day drove approximately 5 miles and could hardly make a hill. Discovered 4 bent push rods, pulled valve covers, pulled spark plugs, soaked with krool and marvels mystery oil and push rods on order. Any recommendations on my next step!

Welcome to the forum. First off, more specifics would be helpful, like which engine this is. Six years is a long time for any engine to be suddenly dry cranked out of hibernation. Its generally a good idea to follow some type of prelube procedure which involves removing the distributor so the oil pump can be actuated without cranking the engine. But the toothpaste is already out of the tube at this point. Assuming the engine is a gas v8, you can hope and pray that one or more cam bearings hasn't been trashed in the process. There are two main causes of bent push rods on the sv8 engines. Over-revving and top end oil starvation. These are hell for stout engines capable of running damn near forever when properly maintained, but neglect is very hard on them. The cam bearings are an especially weak link in the chain. Once one goes, the top end on that cylinder bank begins starving for oil and things go downhill rapidly from there if not addressed properly. I suggest you drop the oil pan to see if there is any bearing kibble present. Take a picture and post it if you are unsure of what you're looking at. Dedicate some of your free time to perusing the threads in the various subforums, especially those that pertain to valvetrain noise etc.

Scoutboy has given you most of the causes but one. Bad fuel is also a major cause of intake valve sticking. The stuck valves will need to be freed and re oiled before running again. Drain all of the bad gas and change the filter. Refill with 5 gallons of fresh ges and plan on adding a small amount of atf to the gas. Say one cup to help untill you work out the varnish.
Thank you very much. I appreciate any and all help that I May receive. I have a mechanic that seems to know what he is doing and will assist me with the push rods. He will pull oil pan and the rest of the push rods to check. The push rods that I have pulled and checked were badly bent and not sure of the condition of the remaining.
Again, I appreciate all the help!
