Hello Forum,
I am very new to the Forum.

My bus was parked for few months, wouldn't start, cleaned out Diesel Fuel System. Service all oils, replaced filters, checked for leaks, bleed out air. 2x glow plugs still not good, BUT...

Once started, it puffs rings of blue smoke, when idling. When rev raised, it turns to black, blue disappears. Idling brings back blue smoke, even with some rings Laughing

It appears there is sump pressure, blowing up into the tappet cover, and forcing into the Turbo via 20mm dia connecting pipe, lubricating the Turbo. Oil rings worn? However, still has good power in the engine.

I checked effect of "when I loosen diesel feed to each Injector" and found No 3 + 4 not making difference.
Removed all 4x, to diesel workshop 2morrow, to see them be good in atomizing.

Am I on the right track? Injectors?

Look forward to hear from you.

Fred, Chingola, Zambia
