When they wear you get a whole lot of extra oil all over that top end. There is plenty of drain area along side of push rods but the extra oil will be slopping all over the tops of those rocker arms and onto the valves. During the hay days of the 460 gas tractors out this way, we had a spanking new one useing oil like crazy. Before I had a chance to get it back in to check it out, IH sent out a service letter. If you are experiencing excessive oil consumption on the C-221 & C-263 engines, first off check the rocker arms. They had two suppliers of rockers and one of them had missed the step in production of pinching the oil trough on the top of the rocker arm. Therefore the valves were getting flooded with oil. I don't think IH was using any type of umbrella and or o-ring at the time. They changed back and forth so much on those it was hard to keep track of it. Anyway, I pulled the head as engine was badly carboned already. Pinched the rockers to specs and also installed PC valve seals. Dried her right up. I have found a lot of worn rocker arms and shafts on those 4 cyl engines over the years. [Reply]  [No Email]

With new guides, or correctly specified valve stem to guide clearance. it should not smoke. I always put seals on valves I hope the seals do the job. Jim [Reply]  [No Email]

If you have way too much oil up there, fix that first. Your drain holes are plugged. Get rid of the extra oil and it can't leak down the valve stems. [Reply]  [No Email]

If the rocker shaft was not put together correctly, that might make extra oil, but it just gets a pulse of oil every time the cam journal lines up with the hole in the cam bearing that feeds the top end measured amounts.
