Oil Leak!

Today, I started up my car for the first time after not starting it up for 1 week in the garage due to a busy schedule. What I found scared me right away.

Name:	650i Oil Leak.jpg

Any ideas as to where the leak may be from? I just had the upper right timing cover gasket re-sealed about 2,200 miles ago.

FYI: I have about 57,800 miles on the car right now.

It could be valve cover related, sensor related, or alternator o-ring bracket related. I suggest to spray the engine down with some engine gunk, & start trying to locate the leak. Oil has funny ways of going all directions, when it starts to leak. You might have to remove the lower covers to get a better look.

Good Luck!

Thanks HerbP. Right now, I have scheduled an appointment for the dealer on Monday. Luckily, I still have about 4 months of CPO warranty left. Would a leak like this be covered under CPO?

I just have one extra question according to oil leak:

If the car is lowered and slammed on a bump, will that cause oil leak and will that oil leak problem will be covered by CPO ?

You will have a hard time trying to get that one covered. If the car is taken out of spec its an excuse for the dealer not to cover the work but will charge for it. This is one of the reasons why I have not done any mods to my cars until the warranty is up.

In regards to the leak, are you sure it's oil? could be a possible coolant leak. The coolant will also leave an oily feel to the touch. Was it on the passenger side? It could be the common O-ring faliure for the Temp sensor issue.

I'm fairly positive that it is oil. Would the coolant color be blue? The leak did come from the passenger side and I found out that it is the vacuum pump leaking oil.

This might sound strange but I had a one-time oil spot in my garage. Someone suggested it might be weather/temperature related.

While this made little sense to me ,there was some serious temperature changes then and it never happened again.

Might want to wait a day or so to see if you see it again.

I had an oil leak in/around the vacuum pump last month - they replaced the pump and seals under CPO. There is also a sending unit right below the vacuum pump that can be the source of the leak. Good luck.

That is great news! Mine just crapped out 4 months after my CPO ended. I did it myself and it wasn't terribly hard, but dealer option is way better. Thankfully an aftermarket company has put together a gasket rebuild kit for us non-warranty victims.

This is one of those cases where BMW's "replace the entire part" is a huge help. If BMW had this as a part that they could just replace the seals you would be out of luck. But since the Vacuum Pump is a non-repairable in BMW's eyes then the CPO kicks in to replace the part.

The BMW coolant is blue. I have never seen blue oil before?

Even though the dealer is not allowed to deny you coverage even if your car is modified, they will do so in order to charge you. They automatically assume that modified cars have problems on the owner's behalf.

Remember underneath your car at the front is a plastic pan cover, so if your sump was damaged you would have to break this cover first, it is easy to check just look underneath!!!!
If this is okay then no slamming has occurred.

Update

According to the SA and service technician, my vacuum pump is ok, but the oil leak came from a worn Mechatronics sleeve. They re-sealed the transmission oil pan with a new gasket and bolt. Total cost with CPO: $50

I'm dreading the day this happens. But you gotta pay to play.

fortunately my mechatronics already happened a few months ago and was covered under CPO (around 80K miles).

I was fortunate also that they replaced mine while still under factory warranty. But it is leaking again 2.5 years later, of course right after my CPO expired!!!

Stupid crappy non-longlasting junkie parts that cheap-ass-bmw uses!!!

ha, no worries, will eventually have an indie get it fixed.

I hear you Mark. It's always the seals that are causing problems along with plastic tranny pans. Maybe BMW planned it to be that way, or these engines run really hot and take a toll on the seals?

True-that. All internal combustion engines run hot! I refuse to let BMW off the hook by blaming anything but what I think it is, making more money by using inexpensive parts.

What a shame. Even the seals on my dad's 2006 Toyota Tacoma with 164,000 miles hasn't even leaked yet(knock on wood).

Very true. Many can afford to buy, but can they afford to own?

Got that right. I have a 99 expedition 5.6L that I bought new. It has 256K miles and no leaks and you can't kill the thing.

Exactly!!! My 2000 Jeep Wrangler that I have put through some 4-wheelin' hell doesn't have a leak. 107k miles.
