Oil in the turbo hoses
 

I have 2013 Ford Explorer Sport with 12k miles. Wife's car and she loves it. The other day the wife comes home and says the car has no power and seems like its a 4 cylinder. No error messages on the dash, but I drove it and she was right no power. I crawled under the car and saw that the post front turbo rubber hose had come off of the plastic tube heading to the top of the engine. Makes sense, no turbo, no power. I reconnected and power returnded. That was simple.
Now the issue, what I noticed when reinstalling the hose was that there was engine oil in the hose. Not a lot but enough to make me concern. Luckily we had an appointment at the dealer already for the fuel tank recall. So we took it in.
The response from the tech was "Small amount of oil found is characteristic of design".
My question is, is this true? Should there be any oil in the air lines? This would be the first turbo I have owned that had any oil in the lines.

hose coming off means she was really USING the boost :) :)

that and the SLIGHT oil mist is not really anything I would be too concerned about....

Most of my previous turboed vehicles did that a bit too...

Keep an eye on it for sure. You might have a shaft seal starting to fail. This will allow engine oil in the charge side of the turbo. But with that new of a vehicle it will be covered.

Thanks for the feedback. I will keep an eye on it and yes I suspect my wife keeps the turbo boost pressure up most of the time. She hates to see any of the 365 horses not getting enough exercise. ;-)

I agree if its just a misting, its no biggie...try owning a 26 year old grand National...then we can talk about oil in the hoses:)

interesting item to keep an eye out for. I have 15100 miles on ours. Wife loves to wind up those turbos....as do I

a screwdriver and 5 minutes is not a bad thing to do to prevent it - just snug them down a bit more and you should be fine... our deezle excursion did that once and it was like OMG, it's a dog, somebody stole half my cylinders :)

Or any leaky, noisy twin turbo audi for that matter....

Oil in the tubes is normal. It is likely from the PCV system and not something to worry about.

I have drained in upwards of a pint of oil from a single audi intercooler at one time. Keep an eye on the oil level, any large (one quart or more) amount of oil level change warrants inspection.

On second thought. After owning several single and multiple turbo cars and trucks, you may want to consider the following.

A charge tube blowing off indicates she was on the throttle hard and immediately let off. A couple of conditions can happen here, both of which can be equally as damaging depending on the situation.

In this situation, either the boost diverter valve couldn't keep up with the rush of boost on deceleration and it spiked, or the valve's action was too slow and allowed the spike to happen. Or, the waste gate can stick in the closed position and cause a boost spike on deceleration too. This condition can be worse in comparison as the turbo could produce large amounts of pressure in the engine when the engine isn't prepared to manage the boost resulting catastrophic failure.

I would bring it in and have the codes scanned for an overboost condition or wastegate malfunction.

GN is a keeper....!
 

Nice ride ..one of my medic buds @ Benning had one and I would run my puny Suzuki 650 against it..... after initial take off he was gone...lol. but hey it was all fun even sober....... :-X04

they are fun:)
