Hi all I've notice blue smoke on over run between 4-2k revs ive also found traces of oil in my intercooler, I removed the spark plugs and there is no oil residue on them clean as a whistle so I take it my VF34 is on its last legs? Thanks in advance

 

Oil in the intercooler is normal.

 

Coming out the exhaust ain't though

 

smoke on overrun i had with a vf35 just before it shat it's self, it's the oil rings in the turbo a bit like a piston ring, mine where coked up and stuck to the shaft allowing oil to pass and come out the exhaust
