Right guys feel free to chat away .

here is the prob i have

RS turbo S1 ..

Engine/bottom end was fully rebuilt 14k ago , and has since had a new head gasket, head skim and arp head bolts fitted ..

car started to smoke on start up ..

so new valve stem seals were fitted ..

car still smokes slightly on start up , when reving the car static at high revs the car continue's to smoke ( light blue) , normal driving it's ok ..

took the boost hose of and on the shaft there is movement a good few ML ..

Car running around the 200 bhp mark

any ideas guys ?

cheers in advance .

Could be oil seals in the turbo on there way. When you done the valve stems did you use the top hat style ones???

 

i used the updated ones , i was thinking/hopeing turbo ..

Which way is the movement? In & out (axially) through the main shaft is bad, up & down (radially) is ok to an extent. Radial movement is for when the turbo spins to allow slight movement preventing the blades hitting the sidewall

 

Hi shawn mate , ive taken the turbo off , there is play side to side and back and forth , also there is oil in the boost hoses ..

when it was running the turbo use to scream on boost ..

Side to side is ok if it's minimal. Oil in the boost piupes will prob be a bit of oil leaking past the seals. Have you flushed through the intercooler and cleaned inside the airbox? Cooler might have oil inside and airbox might be pooled slightly at the bottom and airflow picking it up and through the hoses.
Take the cooler hoses off and blow it through. Clean inside the airbox also: lower hose opening is the easiest place (from box to turbo lower end)

 

turbo seals had it
