Turbo oil lines
I've noticed a small amount of oil coming from the oil supply lines on the turbos.....
Is this typical with higher boost levels or a symptom of something more serious? Planning to replace the lines, just wanted a little feedback from the group. |

The oil line on top (horseshoe shaped) is known to seep. I had mine replaced at about 75 k miles. I did not replace the others.

They seep on my x5d with 138k miles and my 335d with 65k miles. Pretty common for most of us.I will not be replacing them until it becomes more than a seep. I will probably separate the turbos and do all 3 at that time. I do not believe the crimps from the hoses to the fittings had the most robust design from the factory. The hoses them selves are ok. Boost should not effect them

Yep. Solved that problem for me.

Crap. I smelled some nastiness in my car earlier this morning and am not sure if it was my own car I was smelling or the nasty Tahoe in front of me. I guess I'll have to check later.

I replaced all my oil lines recently due to being in there for a different project, and had easy access to all of them. However, I did wonder how one would go about replacing this line without removing all the other stuff ... Is there an alternate way to gain access to this connection at the block without having to remove all the turbo's and exhaust manifold?

So.....this morning I noticed some white smoke under normal throttle. I will now make this a priority to get the issue sorted ASAP.

-remove a/c belt -unbolt a/c compressor -unbolt a/c bracket -remove airbox -remove vacuum accumulator box and some associated vacuum connections -remove turbo heatshields -remove the 5 bolts holding the turbos, but not the turbos All of that gave me enough space to undo the bottom banjo bolt. It almost was enough space to do without unbolting the turbos, but needed extra 5mm as the bolt was hitting the turbine housing of the LP turbo, so that needed to move a tad. This was a while and I may have some faded memories and curse words when I did this. Truly do not wish this for anyone to do unless you are removing the turbos for other purposes, but if you do, replace the #1 turbo oil feed line anyway, just so you do not have to do it in the future. PS: TDIwyze, I am curious about your "other" project. I bet it is something to do with what those scandinavians could do to the hot side of that LP.... |

Thanks for that description. It is the crazy kind of procedure I feared it would be...
