JACUSTOMER-tru21urk- :

Mark :

Did you fit new injectors or reconditioned or just secondhand ones?

JACUSTOMER-tru21urk- :

??

JACUSTOMER-tru21urk- :

brand new from main dealer

Mark :

Only two possible causes that I can think of.

JACUSTOMER-tru21urk- :

wich?

Mark :

Either the high pressure pump has an internal leak or faulty injectors.

JACUSTOMER-tru21urk- :

I try that ,I change the high pressure pump allredy

JACUSTOMER-tru21urk- :

but no luck

Mark :

Must be too much fuel being injected then.

JACUSTOMER-tru21urk- :

non off this.....

Mark :

Must be

Mark :

Excess or unburnt fuel is causing the white smoke

JACUSTOMER-tru21urk- :

I check the injectors again after when I put news one ....and no lik

JACUSTOMER-tru21urk- :

they are good

Mark :

How did you test the injectors?

JACUSTOMER-tru21urk- :

I take the returns pips out and I put 4 pips with for glass cans

Mark :

That only checks leak off.

JACUSTOMER-tru21urk- :

yes

JACUSTOMER-tru21urk- :

but the vans start and run like new

Mark :

Doesn't check flow rate through nozzle or spray pattern.

JACUSTOMER-tru21urk- :

only this prob oil level go up

JACUSTOMER-tru21urk- :

and white smoke sametime

Mark :

White smoke is an indication of excess unburnt fuel

JACUSTOMER-tru21urk- :

yes its true

Mark :

Unburnt fuel is either due to misfire or leaking injectors or poor spray pattern

JACUSTOMER-tru21urk- :

so wht shall I do?

Mark :

You need to get injectors bench tested. Also get compressions checked incase rings are worn.

JACUSTOMER-tru21urk- :

ok

JACUSTOMER-tru21urk- :

thx

Mark :

No problem

Mark :

Hope this helps.

Mark :

Please remember to rate my assistance.
