Sorry I don't have a note of that.

ok no problem , what is the mileage on it now ? the grey smoke

grey smoke is an indication of oil is somehow making it to combustion chamber ?

are they sure the injector causing this ?

if you put your hand on back of tail pipe close enough to let the grey fumes hit your open palm hand , do you smell gas on your hand or you see tiny oil specs on it

Please let me know

Thank You
