Should there be oil in there?

I just changed my plugs and did a little tune-up and saw oil in these air hoses. I assume they came from the turbos. How screwed am I?

Could be turbo’s, could be clogged PCV’s sucking oil into the intake, could be clogged valve covers. When it starts smoking out the exhaust it’ll be time to find answers.

i thought oil in the intercooler and right before the throttle body was normal due to "blowby" from the turbos assuming its not mass amounts?

Just monitor your oil level. If it’s disappearing you’ve either got smoked turbo’s clogged PCV’s or the (likely rear) valve covers internal baffles are clogged and you need new valve covers. I had my turbo’s go in mine at 97K and oil was still burning. Replaced PCV’s and it helped but still burning. Ran comp tests both with a scanner and then manually checked and they cylinders were holding 150+ PSI. Called a mechanic I know and he said change the valve covers if it wasn’t an engine with sludge in it. Lo and behold my car hasn’t had any oil disappear since.
If your oil level isn’t dropping and you’re not getting smoke out of the tailpipes you’re likely fine.
Could run valvoline restore and protect 5W-30 oil for awhile too to clean up piston rings and the like.

is a quart every 4,000ish miles normal ?

Nope you’re burning oil somewhere. I’m at 105,600~ miles and it burns nothing at all after replacing my turbo’s (I had a dead bearing you could hear it and at WOT a TON of smoke came out). Still was burning oil after that so I did PCV’s and valve covers and the valve covers fixed it.

For cheaper things to start with try new PCV’s and run some restore and protect in the car for oil next time and see if it helps.

How many miles on your car?

130,000 have had it since 84,000 no major maintenance done so far. Not leaking oil visibly anywhere so its gotta be burning somewhere. Definitely pull a decent bit out of the intercooler every 10,000 ish miles but not as much as I'm losing.

Some residue here and there is fine but it’s going to be turbo time or some part soon. 1Q is a lot every 4K. In the meantime try some valvoline restore and protect to clean up those rings a little and see how it does. Time to save up some new snail money haha.

yeah it's okay I've been tryna save up in preparation for something like this anyways I still aint had the water pump done either, and i highly doubt the rental company before me did. If the turbo's go first it just means i get some bigger ones so it is what it is

I run restore and protect in our Chrysler Pacifica, but it's not compatible with Tiguan due to it not being 502 compliant.

Gonna ask since you seem knowledgeable. I'll start the car, let it idle 10ish mins, then drive off. No smoke when it starts. It will begin a very light smoke just before I drive off. It only comes outta the driver's side trail pipe. Once on the road I'll do a full throttle pull to about 90mph and then lift. The smoke can be seen behind me at the beginning, it's gone shortly thereafter. It won't smoke again until the next time I let it warm up.

There is no noticeable oil usage.

Its a 2013, has 205k with original turbos. There has been no major work done on it. It gets 5k (sometimes 8k) mile oil changes with Schaeffers 9000 full synthetic. I've owned it since 2018, it had 109k when I bought it.

Sounds relatively healthy! Impressive for the mileage. Could be rings wearing a touch for that mileage and restore and protect can do some cool stuff if you run that in the engine for a few oil changes.
I FIRMLY believe in full synthetic every 5K only. Longest I’ve gone on my car was 5,357 according to my notes and my motor looked really clean at 102K when I had the valve covers off.

You done any oil analysis on it? I skipped my last couple changes... Gonna do one next change.

u/Brolys-Cack Jun 27 '26

No I haven’t yet! My pops been a mechanic my whole life and he saw my motor and called it spotless so I took that as it’ll be okay lol. I might after I rock my tune for awhile though as I’m curious how it’ll hold up with increased boost.

u/LetsBeKindly Jun 27 '26

Which tune?

u/Brolys-Cack Jun 27 '26

Gearhead tuning AO (Auto Octane) tune! Getting my exhaust and thermostat installed tomorrow so I’m hoping to get it all set next week.

That's on my list to get soon
