The engine I working now is a non runner, I reckon I could build a fire under the engine to warm the oil up.

or I need to just wait till Sunday for it to warm up. These under 10F nights don't help. The oil is so thick in the log splitter engine right now you can barely turn the engine over. Molasses comes to mind. I going to put back in the 5w30 synthetic oil with moly.
I got the do a valve guide job and replace the blown head gasket. It should be rebuilt but you know it cost more than the vertical replacement engine with my labor added. I am thinking that the moly will give it a little more life and I am thinking the main problems of smoking is the worn valve guide and the blown gasket.
I got those parts in Thursday afternoon, during our 27F heatwave. The Yo-yo is going back up Saturday.
