Re: 2004 E350 6.0 Blue Spring Upgrade
One note of caution:
When I did the blue spring upgrade the increased pressure caused some injector O-rings to fail, leading to diluted oil, leading to a new engine.
I did notice the oil level going up and went back to the shop that did the work. They thought the dipstick was wrong and changed it out. When the oil level continued up I went to a different shop.
