Can anyone help me identify why there is so much oil just sitting in my turbo? I just replaced the oil feed line two days ago because it was leaking all over the place but I can't figure out why there is so much oil in my turbo. It might be worth noting that if I am doing around 40-55mph in 4th or 5th gear and I accelerate to pass someone it seems like the car sputters and chugs. Almost like I'm playing with a remote control car and the batteries are dying. Any ideas?

 

Not uncommon for these cars using a PCV recirculation system.

As for the sputtering and chugging, you have another issue to attend to this little bit of oil in the intake is normal.

 

As for the acceleration problem, are there any codes present? Check out the threads I've posted below.

That amount looks normal. Have you had a carbon cleaning yet.

Also when was the last time changed the plugs ? Have you checked them ?


make sure when you reinstall the intake tube you dont get oil on the tube or inside connection wipe it clean, otherwise the intake tube can work itself off over time.

 

There aren't any codes present and the plugs were just changed when the feed line was changed. Two of the plugs were bad. It seems like cylinder 4 coil is misfiring but it doesnt constantly do it. Sometimes I start it up and there is no misfire at all and then other times it may do it for a minute. I want to unplug 4 when it misfires but i never get the chance to see if it changes anything because it stops when I'm about to unplug it. I'm also leaning towards clogged fuel injectors so I was going to dump some techron in and see if that changes anything.

Also I have not had a carbon cleaning

 

Your coils are firing at an extremely high voltage, I HIGHLY ADVISE YOU NOT DISCONNECT THEM WHILE THE CAR IS RUNNING.

The injectors on these cars are high pressure injectors firing at over 40k PSI, the chance of a clog is highly unlikely, especially since the injector itself is an electrical circuit a clog of significance would give you codes.

Try moving the coil on 4 to 2 or 3 and see what happens, if the misfire follows then replace that coil, if not then do a compression test.

If you haven't had the HPFP replaced recently you should check the rail pressure as well as have the car scanned for codes, as you may need a pump. In 4th and 5th gear you are over a 1:1 gear ratio and engine load begins to rise, and that is where you will start to see issues pop up if there is a fuel or spark issue.

 

How many miles are on your R56? Just about every 50,000 miles the intake valves need to be cleaned to maintain optimum engine performance. Once the build-up reaches the maximum tolerable level, the engine will begin to run rough and misfire. You may have a rough idle, poor acceleration, stalling or single to multiple cylinder misfires. If you have any of these symptoms, check for valve residue build-up.

 

I just hit 95,000 miles on it. And when I seen the oil sitting in the turbo like that I started to panic thinking that it was junk.

I have not had the HPFP replaced but it has crossed my mind. Fortunately I did purchase an extended warranty when I bought the car, and when I bought it the car had 89,000 miles on it. The extended warranty covers a number of things for the engine including the turbo and all lubricated parts. However, I have to pay for the diagnosis. So if something is wrong and I know what it is I like to tell them so they don't take hours looking for the problem.

 

I would check your coils out and then go to intake an check the carbon build up.

 

Honestly i would say it looks normally... being its so easy to take you're charge pipe off.. ever time i check the oil, i clean the oil out of it ..and normally for me i check the oil onces a week.. After putting a catch can on, it really helps with the problem, will not end the problem all together but it will help ... and remember to keep up on that maintenance best of luck

Come to think about.. yeh do not unplug you're injector when its ruining. being the r56 is a direct injection.. that could have a nast out come. if you have not got it de-carb run some sea foam in it before a oil change .. if you've got new plugs and coils and still having the problem, start looking at the HPFP..

 

My turbo inlet looks like yours --- oil puddles. In my case, it's from the turbo oil seal, not the PCV hose, which is always dry. When the crankcase has pressure instead of a vacuum, the turbo oil won't drain back into the crankcase properly, so it seeps thru the seal into the air inlet. Your PCV (per the Bentley manual PCV is Pressure Control Valve, not Pollution Control) system is supposed to eliminate this.Since mine is disabled, I live with a little oil in the air intake system and occasional smokey exhaust.

Since the PCV system is an integral part of the valve cover, and not repairable, you either spend big bucks for a new one or live with it.
