hi i have just noticed that when i change gear a cloud of oil vapour comes out of dump valve.
could this be the turbo or something worse like worn rings?
how to you check for worn oil control rings?
please help

How can you see the bov when driving? plastic bonnet?

 

th dump valve is wet with oil and as soon as you back off throttle and dumps the charged air it also dumps a cloud of oil smoke/vapour from the o/s bonnet vent so where else could it b coming from?
