Default 318i touring e46 2004 using oil

I'm hoping someone might be able to help me. My 318i E46 2004 touring is starting to use alot of oil. I cant see no obvious leaks and a friend of mine said it smoked a little bit from the exhaust the other day when i pulled away. Its done 134K and runs quite well. The service history is quite good. The oil ive been putting in is 5w40, its used about 2 liters in just over a week. Anyone here suggest some common faults to look at first. I no these engines are not regarded very good anyway.

If it's not leaking then it's burning.
Could be valve stem seals or something even worse

Crank case vent valve would also be worth checking, very common failure on E46's and if its not been done then would be a very good starting point.

As said above though could also be valve stem oil seals. These are normally fairly obvious during overrun, when you next pull away you will get a puff of smoke.

Could be worth having a compression check done.

I only paid 800 for the car I don't want to throw to much money at it. It drives well if it's an easy fix I'll give anything a go.

I'm not very mechanical but I have a friend who is. Are valve stem seals and crank case valves hard to fix/get to in the engine. Would a novice (like me) and his mate who's quite mechanical be able to fix them?? Sorry this is a stupid question, but I'm learning all the time. Never fixed any thing on a car before but I've attempted a few thing recently and had success, so wondering if it's an easy job

I'd bang it through the auction and put your money into something else

Today I drove the car about 40 miles and as I got to the end of the journey the engine management light came on. When I got home I plugged my friends code reader in and it gave me this fault 272c. A quick scan of the internet as given me a few clues could be the crank case ventilation hose. The car has become very spluttery when idle but drives fine. Could this be why the car is using/losing oil

Thanks in advance

Changed the Crank Case Valve and all 3 hoses at the weekend. I'm getting around 200 miles before the oil pressure light comes on. The car rough idles (hunting according to my mechanic friend) and there is white smoke coming from the exhaust when rev'd all this happened before I changed the CCV. The car runs fine and the vanos was refurbished by the previous owner I have bills and receipts for this.

I'm confused how it's been running fine for a while and suddenly started using lots of oil. There are no leaks as we checked when changing CCV. Could I use INPA to monitor the car in real time and check all sensors.

Any light on this issue from anyone will be much appreciated. The oil im using is 5w30 from the local Tesco garage
