so let me just ask this question to see where most true mechanics or people with true knowledge of the Duramax engine.
QUESTION: if your CP3 is going out because of whatever reason, and you think you have pretty good knowledge on how engines are built, to be taken apart and rebuilt, would you do the CP3 replacement yourself or would you just pony over the money and have a shop do it for you?

Wed 14 Ayg '19 @ approx. 4:30 PM MST One look at the multi page instruction sheet from S & S Diesel made it clear to me I made the right decision - turned the job over to a qualified shop.
May I assume you made a typo error, and meant to ask "if your CP 4 is going out".
That's the problem - from what you will see about CP4 failures there is little or no advance warning.
You are assuming the CP4 is repairable. I get the impression from other threads and posts the thing, once it goes bad, is discarded. (? ? ? )
I worked as a truck mechanic during part of my high school & college years, later worked as a machinist's trainee, maintain my own boats, cars & airplane, so I have at least some degree of familiarity with mechanical devices and tools.
Let me tell you - one look at how far the GM dealer had to take that complex piece of machinery apart, and I KNOW I did the right thing! In addition to all the mechanical work, there's all those connectors of various types you either understand how to disconnect and then reconnect..or break....! Maybe you can find and hire that guy in here who claims it is a 6 hour job?

2013 3500 long bed crew cab. Purchased at approx. 70,000; now have 81,000, convert to CP3. Otherwise bone stock except for air-shocks in rear, together with one leaf removed from spring pack for softer ride. Well....went over a bumpy road the other day & the bone fell off....
