Hello, my name is Mark and I will try help you with this.
Does the engine misfire or seem to lack power?
and its fully pwer
Just the white smoke then
yes, just white smoke and diesel mix in engine oill
and oill level go up
Did you fit new injectors or reconditioned or just secondhand ones?
brand new from main dealer
Only two possible causes that I can think of.
Either the high pressure pump has an internal leak or faulty injectors.
I try that ,I change the high pressure pump allredy
but no luck
Must be too much fuel being injected then.
non off this.....
Excess or unburnt fuel is causing the white smoke
I check the injectors again after when I put news one ....and no lik
they are good
How did you test the injectors?
I take the returns pips out and I put 4 pips with for glass cans
That only checks leak off.
but the vans start and run like new
Doesn't check flow rate through nozzle or spray pattern.
only this prob oil level go up
and white smoke sametime
White smoke is an indication of excess unburnt fuel
yes its true
Unburnt fuel is either due to misfire or leaking injectors or poor spray pattern
so wht shall I do?
You need to get injectors bench tested. Also get compressions checked incase rings are worn.
Hope this helps.
Please remember to rate my assistance.
Just had a thought.
Is it possible you filled tank with petrol?
