View Full Version : Turbo cause oil leak?

Quick question. Will holding the turbos boost at pressure cause an oil leak? I was in 5th gear accelerating from lower RPMs. I probably should have been in 4th gear. So it took a few extra seconds for me to get up to speed causing the boost to hold at around 18ish for longer than normal. I was trying to capture the needle bouncing on video. Of course it didn't do it this time. Right after that I pulled in my driveway and got burnt oil fumes out of my air vents. I jumped out and oil had dripped on the manifold area. Never had a problem before. What should I look for?


This is how long I held the turbo. FYI, the gauge is not zeroed. When turned off it sits at -2ish

Here is where I see what looks and smells like fresh oil.

I have that same oil leak, when i'm boosting around a lot, it really starts to stink and burn as it falls onto the exhaust mani.

Hmm..interesting. Do you know if there is a maintenance routine that would prevent this from happening?

Seems like the valve cover gasket and post a picture of the engine bay by what im seeing in that tatherd up vacuum line that tells me you have many other bost leaks thus causing the 17-18ish idle on boost gauge...

It seems to idle around about 21-22. It looks higher in the video cause I'm already rolling at about 40mph. I'll take some pictures tomorrow. I know very little about turbos this being my first Audi. Just trying to keep something from dieing prematurely.

I would say the valve cover gasket, it isn't to hard to replace, i'm changing mine next oil service.

Here are the pictures of the engine bay.

You really should do a boost leak test. Also you should go back to the stock air box. As for the valve cover gasket leaking it may have been a coincidence, or something in your PVC system is clogged and it built up pressure and made the gasket leak.

This would be my guess. When you held the boost the pcv became over pressurized and the oil needed somewhere to escape. I would check out your pcv system (very common to break) and replace your valve cover gasket.
On a side note, that engine bay really need to be washed. And if you are going to run a cone filter on a stock turbo at least get/make a larger heatshield, you are probably burning your MAF up along with a lot of power

I'll do a search for a good tutorial about those two things.

Does a vaccum line replacment kit exist or is it buy one at a time?

no best option for you is go to any oreily auto parts and grab the right size they sell em in bulk 1.29 a foot so not bad at all and just replace worn lines from the turbo wastegate comp housing manifold to tip and so forth...
