Question about Cars & Trucks
This engine still has good power but the oil level is low after 400 to 600 miles. Valve guides worn?
Worn valve guides are indicated when after the engine has been idiling for a while ie at lights etc there is blue smoke from the exhaust when the engine is given some revs. check under the vehicle for oil leaks. they will show up as wet on the underbody. check all oil hoses. loose or faulty oil filter. loose sump plug etc. with that amount of consumption something should be obvious. How having said that I rebuilt a 4 cyl petrol motor for a dodge fuso 3 ton truck and it empied the sump in 100 miles It had a ring problem.. If the motor has been rebuilt it is possible the rings are fitted upside down and act as a pump pushing the oil into the combustion chamber

Yes a crappy PVC valve can cause some of your problems but not necessarily all of them, they are cheap, I always replace it to start. The air cleaner housing being full of oil is like how the oil is being consumed. In addition to a PVC valve, there may also be a blow-by hose running into the housing. check to see what other hoses go into the housing & which ones have oil coming from them. I'm not familiar with the "Motor Honey" you mentioned but I rarely add additives to my Engine oil, especially if they are thickeners. The only stuff I recommend is a Quaker state or similar "High Mileage Oil". These semi-synthetic oils have additives to swell old rubber & cork seals in older engines and can help reduce oil consumption & leakage. Again, it may not be a total solution, but it couldn't hurt to drain out all of the existing oil & replace with a high mileage type & also change the filter at the same time. Never mix it with other oils, despite the manufacturer telling you it may be safe to do so.

could be a few things-(if oil pressure is showing low usually under 20 lbs recheck oil level) bad sensor,oil pump,low oil level ,sludge have truck scanned for trouble code some stores such as auto zone / advanced auto scan for free

There is a lot wrong with "low oil" and low oil is not normal in a low mileage healthy engine.
The dealer is fobbing you off in the hope you will go away.
If the oil is being changed at least every 5000 miles or so there should be minimum oil depletion between changes with only very minor top up needed. Some oil consumption is normal but it should be minimal.
If the oil level is dropping to a very low level in about 4000 - 5000 miles of normal motoring you have a significant problem. The oil is either leaking out or the engine is burning excessive oil or a combination. If there is no leak through faulty seals or by other means such as oil escaping into the cooling passages of the engine, then there is excessive burning.
These engines are known for excessive oil consumption because the problem is a common one in the 06, 05, 04 and previous year builds back to about 98/99. The dealers know all about this problem - as does BMW - and they will try to fob you off until the car is out of warranty because the fix is expensive.
From what you say the problem has not been fixed on your car. Document the oil loss and insist on your warranty rights because your engine is using excessive oil and this is NOT normal in a properly functioning motor with as few miles as yours has. Make it clear to the dealer that you are well aware that excessive oil consumption is a common problem in many of the 325 petrol engines and you want it fixed under warranty.
Then sell the car as these vehicles will cost you quite a bit in repairs once out of warranty and once you clock up around 60000 miles or more. If you have an auto you can expect major problems at about 65000 miles (later if you are lucky) and replacement of the transmission will be necessary. Once you notice any significant problem with the auto transmission it is on it's way out.

some cars with oil level warning light on, it doesn't mean that its only reading the engine oil level is low, sometime the transmission fuid too. Did you check your transmission fluid if it is ok or not? try to check and let us know, ok.

Tips for a great answer:
The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke.
Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.
Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.
Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.
