Problem? Trace oil on the inside of my turbo intake sleeves?

Turbo.

 

Yep. Turbo. When one goes completely out it’ll fill the air to air. Be sure to clean all that out or you’ll get a runaway.

 

No. If the return was blocked you'd have issues, but not a leak.

Is that oil sticky?

 

I'm not one to take any chances. If it were mine, I would change it.

But, I've seen several like this where the oil residue had turned sticky, and I couldn't convince the customer to change turbos.

I PM'ed those trucks, and would pull the CAC hoses to check for worsening symptoms every PM. I never saw any of those turbos fail. FWIW.

 

That's an assumption. I've wondered if these were caused by air filters that were extremely dirty causing issues like these.

Only because the engines I've seen it on were not well maintained before we started working on them.

If you have a turbo that starts leaking oil through the seals, it's easy to see.

Like I said, I'd change it either way along with a new air filter.

 

What kinda engine. Why was the return line replaced? I wouldn’t replace the turbo or boots, clean the boots a bit and check it in a few thousand miles… it it continues or starts to get worse then do a turbo… a turbo replacement can be $10k on some trucks….
