Yeah i need to prove it though. I am probably gonna use die to find the source of the leak.

I'd still take it back and see what they say. $7 dye should help a lot. Hopefully it was a BMW indy shop that did the work. Get a UV light. Really though. If they did the valve covers, timing covers, and thermostat gasket, the line o-rings was an oversight by them. There really is nothing else to leak right there.

So took the car back to the shop today. Tech spent about an hour looking. They confirmed no leaks from vcg, timing cover or oil cooler thermostat. They also confirmed that they did replace the oil lines orings. They think the oil is residual from old leaks, which i dont agree with cause it's definitely new (golden color oil).

I am going to wait and see if oil level drops over time. Not sure what else to do.

Old caked on oil can move down when the engine is hot. Maybe look like new. Did you get their inspection back in writing? May help in the future if they are willing to write down that you brought it in for an issue. I mentioned dye in the past and you said you may use it. If you put the dye in your oil and it shows up, it is not residual. Do the dye. Take a picture.

I wasn't given anything in writing. Dye is next. This may sound dumb but is dye safe to use in the engine? I came across a thread that talks about dye sticking to internals and an engine flush was necessary to clean it up.

It's your call but it has been a proven method for years. I don't see another option for you unless you wait for the leak to get bad. If it is even a leak. I have never heard anything substantial about it being bad for your engine. It's thin so it just works its way out of leaks. I think it takes almost two little bottles for the 8.5-9 quarts these engines hold. You can always do an oil change after you get confirmation. Bye bye dye.

Check your vacuum pump and the o rings on your VANOS solenoids too.
