Thanks again Dangerous 1965, today I drove my truck over to Jim Jessup's Diesel Tune-up over in North Vernon, IN. My brother-in-law highly suggested letting him listen to it run, Jim evaluated it and wound up assuring me that my crankcase pressure was normal (boy do I feel stupid!) he felt that the main guts of it were fine. My fuel pressure tested at 4 pounds so he suggested a Raptor 100gal. per hour pump as well as swapping the stack lines with 1/2 inch lines all the way to the filter. He said that that should clear-up my lopping rough idle, but I probably will have to replace the injectors if it doesn't fix everything. He thought that the blue smoke could be caused by an injector. Today It didn't smoke at all! I think the fuel pressure needs to be fixed anyway so I'll try that and go from there. I guess I just thought the worst about the crankcase pressure. Thanks again man.

Good to hear! If you do put in new injectors be sure to install a 2 micron filter before the CP3! Will really help the life of your injectors!

Thanks again Dangerous 1965, that sounds like a good idea, I have it scheduled for the 21st to have the filter system installed so I'll let you know what the outcome is. Thank you for your time!
