Oil burning and whining noise!

I believe these issues are not related but anyway when i drive around for awhile and stop at a red light or park the car the get an oil burning smell through the vents or around the side of the car (although i dont smell it directly under the hood) i check the oil regularly and it is getting lower. i have a 2001 330ci 5spd. i definetly notice it more after driving harder.

as for the whining noise i can hear it all around the car but is seems to be louder around the intake manifold area. it gets louder as rpms increase. i dont think its a pulley because i had a pulley squeak and it sounded different. maybe the disa valve?

any help is appreciated thanks!

i did full oem cold climate ccv kit, vcg, intake manifold gasket, ofhg, vacuum lines, vanos seals, and cleaned throttle body and icv.

also the oil sometimes smells fresh instead of burnt meaning the leak must be close to the cabin vents right?

and i bought a injector ring kit thinking that might be where the noise is from, but i havent put it in

What order did you do those in? It's possible your failed CCV messed up your new VCG and created a leak before the CCV was replaced. If you did them all close together, I have no idea...

also the burn smell will be extremely present at times under a certain load and other times under the same load it is very faint.

also forgot to mention the belly pan is off the car not sure if that makes a difference though

I have determined it is almost definetly coming from the rear of the engine, which comes to the sad question of headgasket?

Hmmm, I don't believe a bad head gasket would leak oil. Coolant, yes. I bet the rear of the VCG is leaking at the half moons.

Also, take your intake manifold off. There are some rubber plugs sometimes on the back of the intake manifold, and you could just be missing one. Would cause a vacuum leak. If you can get in the area safely, a good way to look for vacuum leaks is run the motor and hold a lighter near the areas you suspect. It would suck the flame in.

I have recently purchased a new tensioner pulley hoping that fixes the whine, I did all those vacuum lines when I did ccv, I can check to see if one of the caps is missing when I get a chance though

The oil loss is now unbearable. After topping off, 2-3 days later no oil shows on the dipstick (not sure how much that equals). It got so low one time there was serious ticking, remedied by topping off immediately of course. I still can't smell the oil under the hood, only inside the car through the vents and on the sides near the front of the doors. The ccv is brand new genuine same with vcg and ofhg. Vcg bolts torqued to exact spec. Having it looked at by a mechanic who's got a lift, but I still have never seen oil puddles on the ground or anywhere for that matter.

So the oil isn't exiting the car? Any white smoke ever? How's the performance. Oil in the intake can lower the octane rating

No white, blue black/grey smoke ever that I've seen. The performance seems to not change when it's lower, but I typically don't drive hard. When driving I get the burnt smell but also the fresh oil smell,on occasion as well

And the vcg is correct? No drops on the left side above the headers? Could be. Burning in the manifold. Without smoke it's really hard how to tell where to go
