Is that the thermostat housing?

What are my options? Should I get a new thermostat along with a metal housing ? And what brand should I go for?

Or should I first check that I don't simply need a new seal or something?

I'm guessing the inlet manifold needs to come off again?
Watch out for a stream of well intentioned, but technically inept posting coming your way as to the reason behind the leak around the thermostat housing.

It is generally caused by a chemical incompatibility between the coolant and the o ring, which causes compression set to occur in the O ring, but can also be caused by poor installation technique

My advice if you like the car, treat yourself to a nice shiny aluminium thermostat housing from Kaiser, fit this and never worry about it happening ever again
