on some of the heads.. the valve spring landings are cut down, into the head, so that they are lower and designed to hold oil around the valves. this is so that when not run for 6 months or more, the valves will not rust or stick. this design on some of the ford tractors also means that the exhaust valves will feed some oil... into the exhaust.
Absolutely perfect valve guides, valve stems, and new stem seals will help, but not stop it 100%. As its called slobbing, many fords will do this when run lightly, and then clean up when warmed up and put under a load.
First off, are your valves recessed into a well or sunken into the heads... its there any play what so ever in the valves in the guides? Lots of machine shops would knule the guides but this is not a good fix. did it get new seals, and are the seals staying seated on the head valve stem boss, or are they moving up and down on the stem and doing no good what-so-ever?
On the turbo... turbos only have a couple of washers on the shafts for oil seals as anything else will burn up from the heat.. Therefore.. the drain MUST BE straight down, and must have NO restriction to oil drain what-so-ever. lots of drains cake up and the size of the passage is narrowed, causing oil to back up on the turbo shaft and then it will start feeding oil... REMOVE the drain line and rod it out to make sure it is 100% open with no build up. Drain lines are oversized to prevent any oil from backing up, but cheaper oils will cake up due to turbo heat and slowly clog the line over the years.

As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
