I noticed a little oil on the garage floor today. My mechanic previously said they thought there was an oil leak but they couldn't figure out where it was coming from and it didn't seem to be bad.



I think it might be from this curved hose that looks like it goes to a turbo, but I'm not sure. It also looks like there is some oil on the back side of the turbo, and since this is high up on the engine, I would think this might be the source.



I tried searching forums and couldn't really find anyone with this problem, but I also don't know what that hose is called. If someone could point me in the right direction, it would be much appreciated.

That's a common problem hose. It's a turbo oil supply hose, not sure what the part number is though

Thank you!

The oil leaks where the arrow is.
The hose is found here http://www.ecstuning.com/ES254125/
Maybe you can get the hose for less money at the bmw dealer?
Don't forget to buy the 4 copper washers

Similar hoses are used on the power steering systems. These always seem to leak at some point. My son has my E46 old with 200K miles and the dealer wants $1000 to replace all the weeping power steering hoses. I always tell my son to decline as it leaks less than $1 worth of fluid a year.

You could probably pull the hoses and run down to a Napa auto or tractor supply and have them make new ones for you for $100. Unless they have done weird non standard fittings on then which wouldn't be a surprise. Power steering fluid is quite flammable.

My car is at the dealer getting new front brakes and carbon cleaning. (76,300 miles) They pointed out oil leak on the hose leading to the turbo. Guess it's fairly common on the 335d. I told them to repair it while they were doing the carbon clean.

Common problem. Very easy to replace.
See below, it's #2 in the diagram and copper washers are #10.





Make sure #1 top attachment to #4 is not overstretched or you will be replacing that too and that will require unbolting both turbos and a/c compressor.

Here is a cheap place to buy #2

Yozh do you know how hard it is to replace #1? I've still got a little seepage after replacing the top oil line (#2).

I believe you have to pull the turbos.

atp-205.... Seriously most of those are easy to replace except for 1 hose. Common diesel issue. Probably gonna do it when I redo my vacuum hoses, vibration damper, etc.

I replaced the oil lines except #1 and still had major leaks. Indy shop hosed out the oil and found that the valve cover had major leakage from the gasket.

You do not need to pull the turbos. a/c belt off, a/c compressor loose, remove a/c compressor bracket, remove vacuum accumulator box/bracket/pressure converters, etc (easy to say, lots of work), remove turbo heat shield, unbolt lower turbo (most upper turbo bolts have to be removed).

Easy peasy!
