I did think that too Craig, just it sounds to me like an IN engine problem as opposed to a chassis bang. I will be getting some new mounts soon, but I think ideally, the engines internals need replacing...main bearings, rings, caps, cams...maybe even new pistons....might make the engine smoother. Although, with you thinking that mate, I may investigate further. 2 people thinking the same possibilities may turn out to be a concrete diagnosis.
