Oil in intake?

Question

i have a turbo and on the inside on the tubing there is oil on both sides of the turbo , what is the cause of this , is this a major problem , i have no other problems , the turbo runs fine , comes up to boost fine as well , but there is oil in the intake pipes , any ideas or sugguestions please

Answer 1

It is normal for there to be some oil in the intake pipes on a turbo but if you take the pipes off and oil drips out it is too much and the turbo needs new seals. do it early and it will not cost much -leave it and you will be up for a new turbo

Answer 2

It Will become a Major Problem very Shortly! Turbo Oil Seals are Gone and the turbo is losing oil pressure. At speed the Turbo Shaft "Doesn't Ride on the Bearings "It Floats in Oil at 4 to 8,000 RPM" therefore if it starts losing oil pressure it starts eating the bearings and shaft. IE; Loud Noises, Damage to the Intake, and yes The Turbo can overheat and Come Apart causing Major Damage!

NOTE; Easy Rebuild for a shop with the Right tools & Equipment.

Answer 3

There is a very precision bearing that separates the hot and cold side of the turbocharger. On some turbo set ups the bearing receives full crankcase oil pressure fed lines to and from this bearing. On any turbocharger a problem crops up sooner or later.
The situation goes like this: During any extended drive the exhaust side of the turbocharger is partially cooled by the incoming compressed air and the pressure fed lines keep the bearing adequately lubricated and cooled. When you shut the engine off there is no longer oil pressure to the bearing and the hot cast iron exhaust turbo fin side soaks a terrific amount of residual heat directly to the bearing. A condition called "oil coaking" takes place. The thin oil film actually burns off from the heat causing a hardened film to form on the bearing. The seals go next.
This is why you're noticing oil in the manifold lines. At this time you can elect to have your present turbocharger overhauled with a new bearing. It would be a distinct advantage at this point to switch to a full synthetic engine oil because the flash to fire point is much higher and most likely you'll never have this problem again.

Answer 4

It depends on how much oil. It's normal for a turbo motor to have an oily coating on the inside of the pipes, but if you remove a pipe and oil is dripping out, it will soon be time for a new turbo or turbo rebuild. If you start to see white smoke out the tailpipe, get the turbo replaced or rebuilt right away. If you keep driving it, you're likely to cause engine damage.
