N62 oil catch can.

You stated on the first page of this thread you have an '06 550i with an N62TU engine? Sure it's not the N62N powerplant? When E60 550i is input in RealOEM, N62N autofills the engine type.

I don't know what to tell you. My receipts from BMW indicate the N62TU - My Bentley and owners manual only indicate N62 & N62TU options. I don't recall any literature showing a N62N. When I bought the car and when I take it in for service and when people see it - they say they have not seen a 550I with the OEM options mine has. Maybe it was a special order - I don't know.

Note: If the exhaust system produces blue smoke, it is necessary to check whether the engine is also drawing oil into the combustion chamber through the crankcase breather, which suggest that there is a fault in the area of the crankcase breather. A clear sign of a problem is an oiled up clean-air pipe.

Must be very interesting, because the exact same message has been posted on xoutpost, bimmerforums, xbimmers, f10.m5post, 5series.net, bimmerfest, e90post, e60.5post, ...(I gave up at this point).

What I don't understand is why this is represented as being a BMW issue, let alone a smoking gun. Wouldn't it be true of any crankcase breather, which could draw in oil to the combustion chamber? On any vehicle, or for that matter, a lawnmower? A similar (but not exactly the same) article is posted on an MGB forum. That was put up in 2008, and refers to 1964 through EOP for the MGB. I don't think BMW had anything to do with designing that one....

My reply to your other post is the reason I've wasted so much time spreading the word on oil consumption / valve stem issues. Not so much on this forum, but others need options with proof to back it up. This has been a long standing issue with BMW's from what I've read - They should make a sticky with proper diagnostic procedures to help people with this issue and put it to rest.

I had never seen the N62 N engine designation until coming across it on the RealOEM site yesterday. This has me perplexed.

Engine Identification
BMW engines are identified by a combined alpha-numeric code. Like the internal model designation it is a code used by the Engineering and Technical development teams dur- ing the design stages of the engine:
• M-forstandardproductionengines
• S-forMotorsportengines(Motorsportisaseparatedivision ofBMW)
• N-forNewGenerationengines
After the letter there are two digits that identify the engine. The table below lists engines by number of cylinders.

I was not aware of the N62 TU engine being advanced to an N suffex. I was aware of the S designation for Motorsport division tuning.

Here's a great link that breaks down all BMW models, vins., engine & trans. #'s.
