OK, more updates. I asked the seller if they had ever replaced the LIM from the plastic to metal one and his reponse was:
" Yes, metal. Has a new metal plentom as well. Head was done a year ago".
I take this to be good news?
That's a good sign, if its true but the head bit is worrying. I hope it means that the head gasket was replaced just as a preventive item and not an actual head.
