OK.. firstly welcome.. Secondly, turbo seal may be on its way out / gone. If its blue its saying there is some oil there. give it a minute and someone a bit more knowledgeable will jump in and help you out im sure.
blue means oil, white means water.. check under oil cap/dipstick and see if water and oil has mixed (will look milky) if it is mixed then your head gaskets gone... or like suggested your turbo seals are gone
VG30TT thanx for ur help,the oil is not mixed and 1 week ago i changed the engine and the old engine has oil leak everwhere, 1 turbo smoke only.thanx agian
