I've read a few posts telling about breaking in a new cam and lifters,running the engine for 15 min or more at 2000 rpm,is this for new cam ,the engine already broken in or is the a new cam and a fresh rebuild. In my career as diesel mechanic, I have dynoed and broken in at least a hundred engines,we went to great lengths to idle these engines as little as possible,just enough time to make. Sure it ran ok and had no leaks.it was set up on dyno and put under lite load until warmed up and then run a varying loads and rpms until broken in.is running a fresh rebuild at fast idle no load not asking for glazed cylinders?
