Take your engine to bits Mark. Don't worry, I reckon some locktite and a gasket set and you'll be as good as new. If you don't get on with it I'll have to come round and kick arse. I was talking to Laurie yesterday and he agrees loose Cam gear. Could be done and running in a weekend??? eg I took mine out and stripped to pistons dangling this afternoon and mine's harder than yours now you have the tow bar off. I few bolts more we'd be seeing what's up with yours. Maybe we can have a little TLB get-together round your place? You provide the chips of course...
