when i bought the car 18 months ago, it had had a new hybrid turbo,head rebuild,piper cams and cam belt (not sure about water pump) it ran sweet up untill now. its got 69000 genuine miles.
i have fitted a front mount and kenlow in between rad and cooler and all new pipes.
i heard hissing from a pipe on the right hand side of the engine and now have a very small leak when up to temp on the left side.

i cant help but think that i have fitted or done somthing wrong some where
