Red face Oil pan leaking after Oil change at the dealer!

I have a 2011 x5 35i... I am sure cars this age can have an oil pan leak... my e90 leaks, my e46 luckily didnt... anyways

So I had no leak on the garage floor since I have owned this car. 6 months ago I had both diffs, trans service, transfer case fluid all flushed and filled. Even after that I had no leaks.

My family doesn't drive this car much and it almost went without an oil change for 11 months... I know should at least get it done every 6 months or so. Anyways now I get an oil change and immediately the oil pan is leaking a lot..

Can it be that the old oil and grime kinda was sealing the pan gasket well.. the new oil is too thin for that? whats going on? I don't do my own oil change and let BMW Seattle do it for $89 bucks.. which is a good price for oil change + multi point check... does it help to go with a heavier oil? or a brand that can help with this?

Any oil pan gasket job on these n55 or n51 is like 14 hours in the book, I almost don't see myself getting it done am guessing..

Has anybody specifically gotten this done?

Had the '13 in for the AB recall and got a clean bill of health except for oil pan leak. Took the vehicle to a local specialist and he took the front end apart, changed out the gasket and put it all back together for $1300 plus the gasket I supplied. $tealer wanted another $1K on top of what I paid for the same job.
4" strip of rubber seal on the old gasket leaking.

An oil change does not interfere with the pan gasket. Drain plugs are notorious leakers for not having the seal properly replaced and for having the threads pulled.

You get what you pay for.

1. How do **you** know the 'oil pan is leaking a lot'?????

2. BMW Seattle sucks. Notorious for screwing customers.

You should drop the plastic undershield and have a look for the leak. I doubt the dealer could have done anything, accidental, to cause an oil pan leak just changing the oil. More than likely, one of the following: the oil drain plug is not tightened, they failed to use a new crush washer, the oil drain plug is stripped and not holding to 25Nm.

They asked me come back in. Still as courteous as always...

They validated:
1. the oil drain plug is tightened to spec - and leak is not from there
2. they doubted the copper crush washer and it not seating right - that wasnt the case they said
3. the oil drain plug is not leaking
4. They cleaned the oil pan and gave me back the truck

What did I get for paying for an oil change?

Everyone on here has their cars worked on for the first 4 years at the dealer right? Do you not trust the dealers anymore for their work? Don't you still go get all the recall work done there for free?

Your comment is not really helpful anyways.

Better right than nice.

No, I balance the benefit of the dealer doing the work and the cost with the risk of consequent damages and the dealers warranty. For instance, I will not ever have the passenger airbag recall / replacement done.

You didnít pay much for an oil. change, maybe your mechanic was a trainee that toofed the job.

I fully agree with Doug. My 13 X5 had oil changes all by the dealers before I bought it. When I first changed oil, the oil plug behaved weirdly. It became very tight before it went all the way so I had to wrench it in. I suspected that the plug thread was damaged. Then I bought a new OE plug which I could screw in smoothly by hand all the way to the end without a problem. It is not that we want to DIY, handing over your car to a reckless mechanic sometimes is far worse than an hour of your time underneath the car.

Going back to your first post. You say the X5 sat for 11 months. How much was it driven between the first 11 month later startup and the oil change? Did the X5 sit through so crazy cold spells in the northwest? A lot could happen to a small unnoticeable leak over 11 months with a lot of changing conditions.

im not sure what you are seeking here....

you want to, uh, 'validate' that changing oil viscosities will cure your leak? Or that a dealer oil change caused or can cause a leak?

Or what?

You have conclusively proven (second hand from BMW of Seattle) that they are blameless. They are saying the oil pan gasket is leaking. You assume this is accurate.

So whats next? You gonna have them fix it?


maybe we should ask this, point blank: did the dealer or other qualified mechanic TELL you 'the oil pan gasket is leaking'??? Is it actually a valid diagnosis?





also, oil change every 12 months is fine. not 6 months

Have you had the shield off and gotten under the car to see exactly where the oil is coming from? Would be good to do that. Even if you aren't going to fix it yourself, at least the theory they present should make sense and match what you have seen yourself.

Totally agree. Takes five minutes and then you can see for yourself, take pictures, post them here for eval if necessary rather than get info second hand.

I purchased my 2013 X5 from Seattle BMW and have had nothing but stellar service since then. In fact, they went out of their way to procure and drivers airbag so that a recall could be cleared so that the car could be imported to Canada when I moved back.
If they cleaned your oil pan it means that they had the shroud off and had a good look around. I'm guessing that they oil drain plug was loose because if you really had an oil leak they would have most certainly provided an estimate on the cost to repair.

Dealer stripped my threads the only time I had them change the oil. I've never seen anyone tighten a drain plug bolt so tight.... I almost needed a breaker bar to loosen it. Dealt with the constant, but minor, drip for 3 oil changes. I cut-in new threads and it has been fine. Probably not a permanent fix, but better than buying an entire drain pan.

Pro tip for understanding: Being right & nice are not mutually exclusive despite what old 1950's movies would have you believe.
To quote James Stewart's character in Harvey...

"Years ago my mother used to say to me, she'd say, 'In this world, Elwood, you must be' Ė she always called me Elwood Ė 'In this world, Elwood, you must be oh so smart or oh so pleasant.' Well, for years I was smart. I recommend pleasant. You may quote me."

It is in fact possible to aim to be both. But he's right about which side to err on.

Regarding your oil pan leaking, here's my experience with oil pans.

I buy a 2010 e60 coming off a lease. It only had 40,000 miles on it.

BMW changed the oil free of charge every 15,000 miles while it was on the lease. They probably told the owner come in around 10,000 and they didn't make it in until 15,000.

How do I know this?

I soon learned the sludge was holding all the gaskets together. That is, nothing was leaking until I started changing the oil frequently and removing the sludge.

I ran an experiment and changed the oil about every 500 miles. It was black as coal after 500 miles. I changed the oil frequently and all the gaskets leaked like they were disintegrated.

The pan leaked, the oil cooler leaked, the valve cover leaked, the oil filter housing leaked.

By the way, there were no leaks on the car when I bought it. It was perfect.

Everything happened when I started changing the oil and maintaining fresh oil in the crankcase.

This is bizarre experience. My 13 X5 also came off a lease and I changed oil every 5,000 miles since I bought it. In the last four years, the only leak was from OFHG, which was replaced by the dealer under CPO. I can hardly believe that clean oil would make all the gaskets leak unless the gaskets themselves are defective.

"sludge" at 15k miles on modern synthetics feels like a stretch.... also keep in mind that oil loses viscosity over time. It is at its thickest the moment you fill it, then shears down over time. The concept that 'fresh oil is thin and thats why it leaks' is...odd.

Sludge happens even with synthetics due to hot spots and the oil losing TBN with age which promotes oxidation.
15k on a hot running bmw gasser is hell on the oil. The stock thermostat they use is higher than the diesels and other brands.

No itís not. Sludge can easily happen on modern synthetics if OCI is pushed too far. In DI engines such as N55 that is especially realistic scenario. If there is a bit more fuel dilution, TBN could be depleted due to sulfur in gas, to the point when oxidation becomes serious issue. That is why BMW doesnít use LL04 in gas engines in the US. Since 01/2017 that is bit of an less issue due to low sulfur gas, but leaky injector or excessive city driving could be culprit.

I'll stand corrected.

Slugging at 15k OCIs, leading to 'self sealing' of gaskets..leaks then uncovered w 500 mile OCIs......
