2001 525i drinking oil

Hello everyone, this is my first post and my first bmw, I have a 2001 525i and I'm going through about a quart every 300km or so and I have no idea what the problem is. I put a quart of Lucas oil stabilizer in it and the oil was fine for 2-3 weeks but now all of a sudden I'm putting a quart in every 4 days or so. The crankcase vent valve and hoses were replaced about 5 years ago and the compression on all 6 cylinders is 200. I've heard it could possibly be a pcv valve? Any ideas or help would be greatly appreciated!

Welcome to Bimmerfest! I've moved your question to the E39 5 series forum, you'll get more help in here. My guess is the CVV valve, they go bad all the time.

The CCV is the PCV on an M54 engine. If your driving history consists mostly of short drives in cool/cold weather, your CCV has likely clogged again.

Thanks for the replies! I'm starting to think it's that valve because everyone is saying that, and I do have a lot of short trips but the weather is not that cold, not good news, I was told that valve is a $1000 job
