I stopped at the services and topped her up, and it appeared that oil was coming out of the top of the dip stick.
Now, i havent got a seal at the top of the dipstick. for some reason the bit of plastic isnt there. I cant remember how long its not been there - it could have fallen off when i checked the oil before we departed London.
Second, is this enough reason for oil to spurt out anyway ?
I took the dipstick out, covered the hole with a rag and a jubilie clip and did the last 100 miles without issues.
The wife was driving and it appears to loose a bit of power now (and then resume) at 60mph - but not at any lower speeds.
Any ideas?
Im going to try and get a decent seal for the dipstick today - or carry on with a bodge. Im hoping its not a terminated 1Y engine

Thanks,
Ringo
