Okay received my 665 back from repair shop reference oil pumping from valve cover breather tube. Oil level was simply going low meaning no diesel pumping into pan. The mechanic said all checked out...engine starting and running well... No smoke..good power... breather tube not clogged etc...the oil would only start pumping out breather tube when operating temperature was reached. He said for unknown reason the crank case was holding too much pressure and he noticed that when he pulled the dip stick the oil flow from tube would stop. His fix was simply adding a rubber breather line from top of round Tac can to left of oil filter thus feeding it back up too valve cover. Worked it hard today and so far it's performing well with no leaks. Thanks for all your help.
