I have a ongoing issue with heavy blue smoke on cold Start
I have recently replaced my turbo after it let go and broke the shaft
I cleaned all intercooler hoses flushed intercooler and check intercooler pipes they are clean and clear of oil?
Also just changed injector seals thinking this might be the problem
It starts lumpy heavy blue smoke then when you drive away it's clears and drives pefect no smoke at all
Then I can stop and start all day with no problems
Until I start the next morning and blue smoke
Have done alot of digging and now think Poss tandem pump???
Oil level seems to be slightly rising?
I am totally lost
Can anyone help me

could be tandempump seal needing a replacement...replacing the seals isn't hard   

could be engine valve seats needing replacement... the latter is found by doing a compression test.

For the 5 minutes it takes, scan it for glow plug problems before diving in to bigger jobs. This usually causes white smoke not blue but the other symptom is a good fit for two or more glow plugs. If you can't/don't want to scan it then check the resistance. You should have about 3-6 Ohms to ground. Anything over about 8 Ohms is effectively open and anything under 1 Ohm is shorted.
