Excessive Oil Use

My 2007 Mini Cooper S is using a quart of oil about every 1000 miles. Only 38,000 miles. Seem excessive to me. I recently took the air inlet to the turbo off and you could see oil on the turbo inlet.

Anybody else seen excessive oil use? Any idea why?

thanks

I'm going to guess that you have a broken piston ring or 2.
Seems to be a common problem.
First thing to do is a leak down test.
That will give some idea to what problem is.
Compression test is another idea.

I remember seeing a TSB where an improved PCV valve was listed. The earlier R56's had more of a problem with oil vapors being sucked into the intake manifold. If I can find it I'll post it up.

both sound like reasonable possiblilities. If a ring is bad wouldn't the spark plub for that piston also be more oily than the others.

I cannot read the TSB since I cannot increase the size so I can read it. Where did you find it?

Here is the thread on our forum...

Gen 2 Technical Service Bulletins (TSB) Database

In my case I didn't download all of the TSB, only the ones after my manufactured date... The one I listed was SIM110109, it talks about some packaging issue with the new and improved PCV and head cover. You need to go back through the TSB's and find the one that calls for the replacement of the head cover with the new and improved valve.

Now I'm not saying that this is your problem but the earlier R56's did have a problem sucking excessive oil.

Good luck

Interesting. I've been warned of this by other MINI owners AND my local service advisors. I've been fairly paraniod about it. I check my oil regularly 2-3k miles and after EVERY session on track. I haven't had an issue so far. Hope I'm a lucky one.

Good luck getting yours fixed. Looks like the TSB database comes to the rescue again. That is an AWESOME resource.

Metalman, thanks for the link. I printed out the TSB and will look at that and the spark plugs tonight.

Hi Scott, A friend of mine has an 08 justa with 48K on it. All of a sudden she is experiencing low oil levels / excessive oil use issue, this is not a leak. Her husband changes oil religiously and she doesn't hammer the car. She took it into the dealer for codes (?). They found it low on oil and it did have a fouled plug, the dealership added oil and replaced the plugs. Hope it's not the mentioned broken rings, she is almost out of warranty.
Have you found out what is going on with your MINI and what the problem is/was?

Never figured out the issue. I checked the plugs and they all looked good. Still runs fine and still uses about a quart every 1000 miles. 48000 miles now.
