Here ya go Mark, they can / should be able to make a custom line kit for you. A kit typically runs $30.00, not bad at all.....



Techna-Fit | Turbo Oil Line Kits

 

Chad from Detroit Tuned developed a better than OEM part many years ago..

That would be me. I have oil build up at the front of the valve cover which appears to be blow by from the cracked o ring. Looks like a bad design to me with the amount of high heat from the turbo. A better design would be a stainless flex line IMO. Has anyone replaced this oil line with anything different than the OEM line? I would think one of the engine builders on here would have a solution.

 

:cornut: Print off the above post and take it(with your MINI) to a local California shop that works on 'a lot of MINIs' and ask them.It will be $100s and $100s less than $1100.

Thanks Jason :fingerscrossed:

 

I found locally for $530. Jason thanks again for your help

 

I had a slow leak from this area and
did the work to replace that turbo oil
line and also replace the oil cooler-filter
housing gaskets while I was at it since
you have to do pretty much the same
disassembly to get to either.
It turns out that the oil line was fine
(I replaced it with the Detroit Tuned
parts anyway) but the cooler/filter
gaskets were not (so of course
replaced them, too).
It took a while to finish the job but
nothing crazy difficult (except drilling
out, tapping and replacing a turbo to
downpipe stud that broke in the turbo housing).

 

I think its likely that your engine may be burning oil, Do a compression and leak down test and see how that turns out. if not check the oil lines that feed into the turbo as they are prone to leak. also check for leaks around anything else that may be hot enough to burn oil off. have you been having any trouble with cold starts?

 

I'll assume the burning oil smell is being drawn in through the front vents. The first thing I would look for is oil seepage at the oil connection lubricating the turbo bearing. That crimped oil line connection has a flexible gasket o ring seal. They are known to start leaking after awhile. I suspect MINI is aware of this since the came out with a heat shield that clips over the fitting (see pic). Tightening the banjo bolt won't stop the leak if the rubber seal inside the crimped fitting is the culprit. The oil line will need to be replaced..... If this is where it's leaking......

Item #20 is the heat shield
Item #6 is the suspect oil line.

 

A friend of mine just had that part replaced... it's a known issue- the rubber cracks and dries out and then you get the oil leaking and smell.

I'd get it checked out/replaced asap.

 

Funny thing.... One of the guys mentioned smelling oil during our dent party. Sure enough, failed flex seal at the crimped joint.

 

Good idea Mark. And if the line had a larger ID, that would also be better. Less chance of getting plugged and coked up. Better oil flow as well. ...

 

Sounds like a good idea for an upgrade.

 

I took mine in for burning oil, and the smell.. It turns out the oil pan was loose ever since then it has not come back. If you need the torque specs, I can look them up.

 

If I am to go to a mechanic, how much would he charge? I mean I would buy this part to replace the turbo line leak. Locally I was told this cost me $1100.

 

Thanks for the heads up on this I too took my Mini into Global Imports here in Atlanta due to the 1/4" slide of the turbo oil inlet line. I was quoted $1296.39 for the repairs labor being $1072.88, needless to say I had a tow truck come and pick up my '09 S and tow to a local repair shop where I will have this done using the parts you mentioned above as I feel this is a terrible design having a crimp connector on a part that gets so hot and what happens to metal when it gets hot - it expands so over the course of 70k miles it will start leaking.
