JD, there is a reason for the high pressure oil system - EPA. The old third rocker was not precise in fuel metering, and therefore was not as emission friendly as the high pressure system. FYI, emissions, fuel economy, and drivability need not be mutually exclusive. Trouble prone systems plague ALL manufacturers. Many of them are mandated by the gubbermint. Tier IV and later diesels are something we will have to live with for a while until more reliable technology comes along.
A point of information - thanks to electronics and such, a 3 liter class engine puts out 200 horsepower, almost ZERO emissions, and gets over 20 miles to the gallon while pulling a family sized sedan. You are old enough to remember that a typical '60s or '70s sedan had a 5 liter or larger engine, made less than 200 horsepower, got 12 miles to the gallon, and the exhaust stunk to high heavens while polluting our air. Don't you think that some of the new technology is doing its job? I also think that they are now going overboard with some of the electronics, but that is for another thread.

They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
