HMM SOUNDS LIKE THE OIL SEALS IN THE TURBO HAVE GONE TO ME U SAY U FITTED A NEW TURBO OR WAS IT A NEW SECOND HAND ONE?

YES THERE IS A OIL PRESSURE PLUNGER IN THE OIL PUMP ITS AN UPRATED SPRING WHICH INCREASES THE OIL PRESSURE! ALTHOUGH CAN'T SEE THATS YOUR PROBLEM AS ITS THE SEALS IN THE TURBO

HI,

Could be the turbo seals, but check the engine breather system is clear,
as back pressure will cause oil drain problems back to the sump,
and oil will pass the turbo seal on the turbine side and out the exhaust
if bad you will see a lot of oil residude in the exhaust ,
check also the air filter is good not blacked, and last take a breather pipe
off the rocker cover and feel if high crancase pressure from worn comp
ring's.

Im no mechanic but would this be down to not priming the turbo prior to use?? Just a question

thanks for more imfo chaps the turbo was in very good condition and it was rebuilt last month i have cheaked all breather pipes and my only consern is the intercooler is or was full of oil but have cleaned that,my exhuast is dripping oil out but theres no oil coming out the actator arm??
the bottem end has also been bulit about 1k ago iv also cheaked the exhuast ports and there clean dry,
iknow it sound stupied but iv read on here that the oil presure switch has some operation to do with this is this correct or not???????

ford have told me that it has a reputaion for blowing turbo seals as this is my 4th turbo know and it really starting to pi** me off?if icant cure this problem what will ido shall isell or look for another engine???????????

I wouldn't go that far mate....lol

Its just the luck of the draw.. Some people have loads of problems and others dont..

Was it a proffesional build... It does sound to me like the oil seals on the turbo are shagged.....

ithink im gona put another bottem end on the car with another turbo and that may cure it as iv tryed every alternitve?????thanks any way???
