Oil In Turbo?

[lozza]

Hey guys,

in the process of ripping off all the old crossover and piping to make way for nizpro gear I noticed when I took the pipe off the fron of the turbo, there was oil around the inside of the seal and mouth of the turbo. Is this normal or should I get it checked out?

Cheers

Pretty normal to have a little bit lining the inside there.

So long as there isn't excessive oil there it should be ok. I'm pretty sure its from the rocker cover breather which circulates oil vapour back into the intake (where the stock crossover is).

ahk yeh, I noticed that hose, wasnt 100% sure wat it was but that would explain. Yeh it doesnt seem like a broken seel or anything, just a lining around the joiner.

thanks mate.

Turbocharger Inspection and Verification

NOTE: It is normal for a small amount of combustion gas to pass into the crankcase. These ’blow-by’ gases are scavenged into the air intake system through the positive crankcase ventilation (PCV) system.

Some engine oil, in the form of a vapour is carried into the air intake system with the blow-by gases (this engine oil also contributes to valve seat durability). This means that oil will collect inside the air intake components and the turbocharger. This is not an indication that the turbocharger oil seal has failed. The turbocharger oil seal will not fail unless the bearings fail first, which will cause the turbocharger to become noisy or seize.

Do not install a new turbocharger due to oil inside the turbocharger or the air intake components. If a leak is detected in the oil supply or return tubes or connections, locate and rectify the source. Do not install a new turbocharger due to an oil leak.
