Volvo S70 T5, i had my pcv and timing belt changed 2 weeks ago, the reason for pcv change was dipstick would pop out after a long run and a bit of hard driving, however the system wasnt blocked. Also changed the oil fo r castrol edge 10w40 as i have this done every 5k miles.

Well today took the car on a 250 mile round trip and it has pissed oil out everywhere again, im getting really pissed off with this now, been trying to get it in with Tim for a year now for this and a misfire problem, Any help appreciated
