Cool pics mate, car looks great on track
Good times around Combe is anything around 1m 20s for a road car really, I know the Radicals lap at around 1:08 or something crazy and Nick Williamson (Owen Developments tuned Escort Cosworth) runs a 1:10 around there which is seriously quick for what his car is!
As for it being boring I can't say I agree, it's short lap but can be quite technical to get right, I love Castle Combe and visit regularly
EDIT: Dont worry about your Oil Level Indicator, it's because you were on track and it couldn't get a consistent reading, mine went when I was doing short journey's and shit me right up!
