Started on the car again after work, stripped the intake, airbox, cambelt cover etc.....and cleaned head off. Got new rubber rocker cover gasket, drive belt, cam belt and a new oil cap.
Drive belt and cambelt look like they've been on a while, will get some more pics tomorrow.
All back together now and ran up, seemed to struggle to start with but once warmed up it idled ok.
Old belt, starting to get a bit thin!
All back together again, gave everything a good clean too.
