smell of burning oil has crv 2.2i-ctdi  got a pvc valve

Hi.....welcome to the Forum

 

Where is the smell coming from (e.g. under the bonnet, inside the cabin, etc) ?
Also, is it consuming engine oil ?

 

In normal use, and assuming it the engine is 'stretching its legs' then very little oil should be being burnt and I would investigate this as a matter of urgency.

If you take the oil filler cap off when the engine is at idle then there should be very little plumes of oily vapour being emitted....excessive amounts could suggest the rings are gummed up with carbon or worse.
Sometimes, an oil or fuel additive can assist in reducing the amount of oil being consumed in combustion.
 

Check rear brakes locking on especially on the automatic
