No need I imagine......It’s an easy job with the engine in

 

I'm ocd like that though

 

Rank is correct. I left it up to the shop (I have known these guys a long time and trust them completely), and for things like the water pump and oil cooler that are not difficult to change they decided that after inspecting the various components, if they looked good, just to re-use them. It would be different if I was running over the road still and putting on 150k a year, but no more miles than we run hauling our equipment, we decided to gamble a bit to keep the price from getting out of hand.
Your point is well taken though, and for most it would have been wise to change it.

 

makes sense but yeah I'm really nuts man. I start replacing everything. I'm not 100 percent normal. I'm a little weird hahah

 

Check the Turbo for oil seeping into the intake or exhaust side, that will cause blue smoke when cold and eventually all the time as it gets worse.

 

A water pump for a B is north of 600.00. I believe in not being cheap and fixing it right, however there is no need in throwing away money.

Taking a B model to most CAT shops won't get a quality overhaul. Most good B model mechanics are dead and gone. Mechanics are only factory trained on the stuff that is new when they start and forward from there. So unless you know the shop like @Oxbow does CAT or independent keep your B model away from them.

As far as the blue smoke it's normal in cold weather say 40° F and down. Should quit once it warms up, idle clean but give a pure black puff of smoke between shifts till turbo spools. Then Clean up and pull like an ox

 

Most likely, but not always. The way to tell that is when you roll into the throttle and it gets to full boost, slowly gently ease up on it till the smoke clears. If it clears up around 3 psi drop and pulls good yes it been turned up. If the smoke doesn't want to clear it is usually a boost leak. Could be the wrong nozzles for the pistons as well. Or a timing issue

 

A mechanical engine will smoke on cold startup as the mechanical timing has curve limits unlike electronic timing that has a wider range of timing to deal with the smoking issues.
. I would say if you are not using alot of oil and are pulling good with good oil pressure. Also injector nozzles are a wear item and disperse more fuel over time. At
least that was my experience in the field.
