Hello, thanks for letting me join, I imagine by now, your Very select group.
I have a 2.2 Vel satis and it seems to me that it is suffering from positive crankcase compression. There seems to be no breathing from the feed pipe into the cam box. My question is, is blockage of the crankcase breather a common fault, and has anybody fitted an oil breather collection can to solve the problems. I have blanked off the edge valve and this has curred the black smoke and no power issues but the injection warning light still comes on at higher revs, which makes think it's crankcase compression
Thanks for this it was helpfull and i'm sorry for not replying sooner, been away. I did as you suggested and the glove did blow up. i traced the breather pipe that comes from the cam box into what i would call a distribution junction, some of the pipes go to the pressure regulating vavle which i think regulates the turbo pressures, and another i assume went to the ecg vavle which i have blanked off. i put an airline to the breather pipe with catastrophic consequences, all the breathe pipes blew off. i removed the dip stick and the engine was breathing quite heavily through the dip stick hole. To prove a point i've attached a pipe to this and attached it to an oil catch can. I've now driven it around for a week in this state and the car is running much more smoothly and nolonger deposits oil on the road, but ive still not found the engine breather. I've even been to the renault dealers but to no use. I have read about the renault Clio having the breather in the cam box, might this be the case with the vel satis as well
