Dave,

Here is a good site that explains the care and feeding of diesels. It was written by an engine guru named Adrian Duncan. His explanation of how and why to break-in an engine is excellent.

The site itself has LOTS of good information. That is where I found the break-in procedure that I use.

Bear in mind that there is seldom only one way to do something. :-)

Enjoy.

George
