Hey Al
Smokeing diesel engines never a good thing especially at the begining of the season. You have a lot of hours on these motors so could be just about anything from valve stem seals to ???
Their are no concrete findings hear with out a lot more info. [Disclaimer] I always try to start with simple to complex ideas when attacking any problem, especially mechanical issues.
Diesel smoke;
Blue smoke is usually caused by oil being burnt by oil running past valve guides, piston rings sticking, carbin build up, plugged piston cyl. cross hatching are just a few reasons.
White smoke is certanly caused by raw fuel coming out of exhaust, ck. injectors, injector timing or water entering in the combustion chamber, head casket, or a crack in the head or
block.
As I said earlier go, simple to complex.
start by thinking about all the last repairs that were done to this engine. Ok any clues? Ck. coolant level, see if turbo spins freely, ck oil for contamination[white
mayo lookin stuff on dip stick or on oil fill cap. or oil level to high and smelling of diesel fuel. [injectors ] Ok everthing cks. out good maybe a good time to put
in fuel and oil additives before you start pulling da motor apart. Get oil additive that can clean any de-carbinize your rings and cyl. walls and a fuel treatment
to clean da injectors. I'm thinking injector sticking open or valve stem seals are hard and oil is leaking past them.
Next step if after a long cruise or two and the problem still exist would be to pull injectors, exam and test/rebuild if necessary and a compression test.
Let's stop here and see what happens. Post back or send me your phone number and we can chat like normal people.
