how old is old? Back before detergent oil you definitely didn't want to
stir the **** up. Back when you adjusted valve clearance, I've pulled
valve covers to find what looked like a thick coating of grease.
suddenly introducing them to detergent oil wasn't a good idea. I think
that's where the paranoia about going from dino to synthetic came from.
Years ago, I had a K car with the 2.2Ltr 4cyl which had some miles on it and some gunk had built up in the engine. I drained the oil and with the valve cover off, I used a parts cleaning brush and diesel fuel to clean the valve train. I then poured a gallon of diesel into the crankcase by pouring it over the valve train washing the rest of the gunk down through the drain holes in the head. After getting the diesel in the crankcase, I took a 1/4" plastic air line and threaded it through the drain holes in the head until it got into the oil pan. The air line was then connected to an air compressor and the air turned on to cause the diesel to splash around in the crankcase to dissolve the gunk. I drained the crankcase and repeated the cleaning. After cleaning and reinstalling the valve cover, I installed a new oil filter then substituted a quart of Rislone for one quart of the new high detergent oil in the crankcase. I ran the car for several hundred miles and the oil was fairly clea
r when I checked it. The little engine stayed clean and the oil wasn't that dirty when changed at 5,000 miles. I never had a problem with the engine which was still running quietly when I sold the car. ^_^

I think if my old van had clean oil in it it wouldn't want to start!
If the oil was kept clean it would run a lot longer. (and may not
have corroded the oil cooler)
