Good morning ya'll,
I have failed to change my oil in ohhhh bout 10,000 Miles or so. I asked a backyard mechanic I know. He actually races trucks, Well anyhow he told me that my valves are tapping but only do it for bout 15 miles then it stops. Some days they don't even tap. Well he recommended that I run a quart of diesel in my crankcase run it for 20 mins then drain and replace with fresh oil and filter. He told me that my oil pressure takes awhile to build up and by flushing it with diesel it will clean out my oil pickup tube. Now if I do that whats the recommended oil to run? Its a 89 ram 50 2.0 5-speed with 122,500 miles on it. Any help would be greatly appreciated. Thanks
