Well, it all depends on how much sludge is inside the engine. A number of years ago I bought a 1939 Farmall H that we were able to make run so we could drive it onto the trailer. Maybe I should say that it barely ran. Anyway, once I got the tractor home I pulled the valve cover to set the valves in an attempt to improve the way is was running and I could not see where the valves were. The valve cover was that full of sludge. I then dropped the oil pan and you can guess what that looked like. Well, I could not hurt anything with the engine in that condition, so I pulled the tractor out the shop and got out the pressure washer and started washing the inside of the engine with hot water and a degreaser. I let the engine set and dry overnight and then put it back together and filled with 15w40 oil and started her up. The tractor engine ran better after a tuneup and I was able to check out the condition of the rest of the tractor before I pulled the entire tractor apart for a major overhaul. Sure was much easier working on a clean engine. I'm including a picture of what it looks like today.
