Audrius

Hello Help please, I got lexus is 200 diesel 12 plate Problem is engine oil disappears no oil leaks, no oil in coolant, no mayonnaise on cap, But I think crankcase pressure is to high, then remove pipe from rocker cover which goes to air intake pipe it's got high pressure then engine on idle and you can see oil marks on air intake pipe . I look for pcv valve but I can't find it Maybe someone had this problem Many thanks
