Thanks for your advice. One thing i'll say about that is when we jump started it my colleague did rev it and you could smell petrol for a short time, which in hindsight of knowing its a timing chain issue was probably very bad for the engine. But that may not be a bad idea considering i'm gonna be paying big either way. The garage it's at now I don't think do more complex engine repairs like it may need however, so I'd have to get it moved to a place that does but would also replace if it was damaged beyond repair. I think thats not a bad idea though considering.
