Loosing oil

[JjCowley]

Hi all, new to this site, but hoping someone may be able to help.

Bought a 2006 aurion, drives great, doesnt loose water, still has the power you would expect.

When i test drove, there was nothing out of the ordinary, when driving it home however.....when taking off there was masses of smoke comeing out tailpipe.

Pulled over and when you put foot on gas, heaps of smoke comes out, got it home, used heaps of oil. Ended up changing oil(did flush also) and put in new filter.

Seemed ok, took to work, but when the car gets to operating temp it starts blowing heaps of white/grey smoke, and i mean heaps, probably burnt through 3 litres of oil on a 60km trip.

People have said valve stem seals -but seams like too much oil loss for that.

Other thought cracked head or head casket -but not losing water or running or ideling rough.

Someone did a compression test on front 3 cylinders, it read very low, but wondering if that would be a correct reading as if there was low compression in 3 or more cylinders,would it not be lagging power, its definitely has got plenty of power.

Is there something that could be causing oil to be vacuumed straight into exhaust when the car gets up to temp?

Any advise or thoughts would be great,

Thanks.

Check and clean the Positive Crankcase Ventilation valve.

Something else you can do is to disconnect the hose from the PCV valve and block the end of the hose with a bolt or similar solid object. This eliminates the possibility of oil being vacuumed up from the valve cover into the intake.

If after doing this hose disconnect, the engine is still smoking badly, then looks like you will need to have a leak down test to identify what engine repairs are most likely required.

If there is no more white smoke when driving/accelerating hard, then have a good read of the attached document and do a Search of "white smoke" on this Forum.

Did you buy your Aurion from a Dealer with warranty? If so, take it back and get them to desludge the front valve cover and replace the PCV valve.

Just wondering how many km it has done

From past experience, I know that the difference between the full mark on the dipstick and just about nothing on the dipstick is 1.5 litres. Engine oil capacity is 6.1 litres. Loose enough oil and the oil warning light will come on; also past experience with the rear V V T i oil line.

I would be interested in knowing exactly what oil you used. A lower viscosity oil will be more easily drawn past worn piston rings and/or drawn into the intake manifold if the oil channels in the valve cover are sludged up and the PCV valve is not working properly.

Did you check the service history on this vehicle and verify it? These motors NEED to be serviced regularly.
