Ok, I wouldn’t be against doing that preventative maintenance. It might’ve happened this past winter if John Deere would’ve got it in for inspection and they were suppose to do valves. They didn’t get to it. We’ve also done two overhauls on a 6.8L in a tractor because of what we finally believe was fuel injectors making pistons delaminate.
