I'd vote for valve guide seals. Been there done that on my (former smoker) 20v.

I got the car with ~152k a few years back and it has around 173k miles now. I was down visiting her (in the San Diego area) this weekend and noticed it seems to be smoking worse and she says she needs to add oil a lot. It was due for an oil change so I suggested we up the weight (was 10/40, trying 20/50), start tracking consumption more closely, and add some (Lucas) seal conditioner stuff to top up next time it goes low and see what happens.

It runs great, but does have a check engine come on intermittently (but the codes are always 4-4-4-4, nothing stored)--I am guessing o2 sensor not liking the oil/smoke being the most likely suspect there. Anyway, in all my years of owning Audi I5s (11 and counting over almost a quarter century) have never had to deal with a smoker, but I gather valve stem seals are a pretty common cause of this. Given I have not yet been down this path I don't have things like valve spring compressor and valve stem seal pliers. From what I can tell the job is pretty straight forward, but if anyone who has some BTDT experience can advise it would be wonderful. Better yet, if anyone has the tools they would like to rent, loan, or sell cheap please let me know.
