Thanks teoman, I'm determined to get this sorted this year - I'll let you know how it goes.
Your DIY sounds great oil pan, but don't think it would work for me.
I've looked at the link you posted skyking, but no luck! I swear to god, I don't think this engine has any freeze plugs! I've searched through loads of pics of stripped down engines on ebay, and the only thing that looks close is a plastic plug on one of the plastic coolant hose junctions, but more likely is an alternative placement for an ECT sensor (same engine fitted to both Ford's and Citroen's).
If there are any they must be behind the cam belts, under the valve covers or something.
Anyway, I'm at the point now where I'm going to buy a unit and hopefully the Chinglish instructions will make things a little clearer
