"car trouble "
Heard a lot about that engine using oil as you describe , but never heard of a definitive answer . Came across this which might be worth checking .

this has been mentioned on previous post for the z16xep engine ( p = twin port )
the breather from rocker cover to inlet ,suffers from a valve breaking
so instead of a limited amount of vacuum being applied ,full vacuum is present .
the cheapest way is to cut and block the breather to the vacuum and fit a atmospheric breather filter to the rocker outlet .
this will at least prove the point and then if the customer so wishes you can go on and spend a couple of hundred quid replacing rocker cover and modified vent valve .
Hope this helps .
