Hello all. I have a random oil consumption issue. I have to keep an eye on the oil level pretty often. Some times it uses oil rapidly other times I cant see that it is using any. Needing some suggestions of things to look at.
Some background. I am not new to TDI. I know how the intake system works on these cars and that it is normal to have small amounts of oil in the intake system post turbo. My intercooler has been leaking oil since I bought the car back in October 2016. Since I got the car it would leave a dime sized oil spot below the intercooler maybe once a week. In the past month or two it has been leaving larger puddles on the floor. I dont clean it every time but after 2 weeks it was probably basketball sized. Since it leaks I cant really say for sure how much it would be holding if it didnt leak. Also I know to drive it spirited every once in a while to keep it the oil cleaned out and keep it from pooling.
My first thought was the turbo was going out. Tonight I pulled the intake tube off the turbo inlet to check for axial play. There was none at all. A very small amount of sideways play. Can the turbo still be bad if there is no axial play?
I have noticed that the small hoses connected to the hockey puck was getting oily and grimy. Also the intake tube where it connects to the turbo inlet has an oily film around it.
I havent checked compression but the car runs like a top. Runs the same that it always has. I try to check the oil very often since the leak out of the intercooler has gotten worse. Some times I can drive a whole tank (1000 miles) and it hasnt used any oil. The last 500 miles I drove it used over a quart though. It seems to be fairly random on how much it uses.
Any suggestions?
