Help needed: a6 oil leak issues!

Hi there, I have an Audi A6 2001 sedan. About a month ago I noticed oil on spark plugs so put in to Audi mechanic and had repaired and services. Only had it home a day or so when the cam seals went. Back we go and have them repaired. Drive home park and oil still everywhere under car. This time it's the oil pan gasket which is replaced. Get home oil everywhere again back the mechanics to be told it's a engine oil sensor leaking. I'm outta pocket over $2000 by now and car still leaking. He repairs that issue not leaks at garage. Drive home pull in drive look under car oil everywhere another leak! I'm outta money and patients by now. I'm wondering what could be causing this persistent oil issue. I've read about the breather hoses and valves causing compression issues as I think this has to be a problem for sure. Any advice would be appreciated. It's sitting in the drive way leaking oil and I'm not sure what to do with it.

Wrong forum, you should try the C5 forum, but it sounds like you need a new mechanic.

First thing to do is replace the entire PCV system. Any clogs in those lines will cause major oil leaks.

Then, do the half-moons on the cam tensioners.

Don't forget the vacuum jet pump. Some only change the "spider hose" set, but the jet pump clogging up or breaking is very often the root cause. If you go with non-OE piping, bends can be a bit stiff so make sure connections are tight and not leaking.
