How many miles on the original housing, And if it is the housing find out exactly where, if it's connecting to the block all you may need is a new gasket ring, If it's coming out where the housing is connected by three screws then you need a new thermostat. But check the hoses and make sure none of them are worn and leaking. Basically you need to find where it is coming from exactly. Then it's easier to tell you how to fix it.

Welcome to FF.

Yea the big problem with them is if oil leaks out the cam cover onto it, then it cracks.

It runs cold for how long? Where does the needle on the gauge sit? I mean they could have given you a bad thermostat, the way it works is when it's hot it opens and cold it closes, so put it in a pot of boiling water and see if it opens, and then put it in the cold and see if it closes.

Hmmmm?, Well it very well might be a bad thermostat, but it could be the head temp sensor too. I would check the thermostat out, test it and see if it is faulty. If it's not faulty you might need a new head temp sensor. But check the thermostat first.
