SOURCE: White smoke from exhaust
its a pvc problem had the same thing in my car when driving slow a little piece in the pvc is clogged and the smoke instead of coming out slowly comes out alot cuz the pressure gets built up

now this may be a long shot... but i had a similar problem on my cutlass. but it wasnt wiring...... it was from the tube running from the head of my engine...... the smell and smoke were coming from hot oil coming out of the crank case vent tube and then being sucked into the air inlet for the heater/ ac.
since a electrical wire's protective cover is petroleum based as is oil.... they smell very similar

This is quite a common problem,especially with the 2.2 dci engine,although as usual Renault wont admit the problem.The reason your engine throws the oil after a run and not when stationary is this problem is caused by the turbo pressurising the crankcase.You can rev the engine all day but when theres no load on it then the turbo is not working at full pressure and all is well.
The cure for the problem is to fit a new rocker cover which incorporates part of the inlet manifold.The breathing system on these engines is complicated and the rocker cover has to handle both inlet gases AND exhaust gases and although no one can explain why a new cover cures it,I suspect the plastic the cover is made of is not robust enough and either becomes porous or warped and this allows gases into the crankcase,pressurising it and focing oil out either through the dipstick or it blows out the blanking plug in the timing cover.
It is not a massive job to replace the rocker cover as long as the injectors come out easily.If they dont then youre in real trouble.Good luck,Duncan.

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.
