Hi Guys,

I have a engine oil leakage in my E60 '04 525i (M54). After few Indy's had a look at it and unable to find where the leak is coming from I had a good look from top and found the oil is coming from the sump (pics attached). Leakage is not that bad, but I don't like . Does anyone else has this problem, and found the leakage from sump? How much is it to fix? Is it worth fixing or getting rid of the vehicle?

Is sump fix a possible DIY?

did you have a look at your oil separator and all of the hoses going to/coming off of it?

Checked and found two leaks, the Sump seems to have a very minor leak as seen in the pics above, the major leak is from the oil filter housing gasket. Do you think the minor sump leak in the pics requires addressing as well or will get worse?

Here are some pictures of where I can see the oil.

1. First - There is oil getting accumulated in a puddle around the 1st and 2nd spark plug start from driver side.
2. Second - There few drops of oil between wiping it clean around 4pm and 12pm next day morning. The picture is of the bottom front left corner straight under the vanos areas.
3. Third - there is slight leak under the cover of vanos, but also the two electrical connector on the left of vanos appear to be leaking oil. Can this oil leak slip down to the second pic.

Which part is leaking that I need to fix is what I need to know considering the pictures. Is it the cylinder head gasket that is gone? Or something else.

Any suggestions are welcome.

$300 at a local BMW repair facility, not a dealer. I have not had it done since like you mentioned, it is a slow leak. I did have to add a quart inbetween oil changes the last time. I usually change my oil every 8-10K.

Further to original post, I did observe under the vehicle, two oil leaks. One appears to be sump leak (front bottom right corner of the engine - 1st pic), the second one is what is confusing me as it seems to be between the engine and the torque converter (right bottom back corner - 2nd pic, the oil is leaking from the bolt at the bottom which is coming from inside), but the screw that has the oil is coming from the engine bay. So is this the engine sump or some other gasket between the engine or the torque......

Also, looking at the oil drops can people contribute there experience if this is heavy leakage or small leakage or really small leakage. After changing the OFG and VCG recently (to which I was losing about 1 litre in 3-4 weeks with 250-300KM driving) I don't know how much I will be losing now. But would appreciate your experience contribution here.

Any suggestion on second pic are welcome. Is it sump or some other leak between the engine or torque converter?

Also, does anyone know if it is possible to repair a sump leak without removing the engine, just from under the car.

If I were you, I'd cleanup the area (rear of the engine, from the bottom) and watch where the oil is originating from. I'd say it's coming from the valve cover gasket.

Wish I could believe you, but it is not VCG.

Who cares, it's a BMW, it's going to leak. Especially if it is over 85K miles.
