How sensitive is the 16v turbo to overheating?

Last year (August/Sept) the fan stopped working when I was miles from home attending an Alfa meet.

I didn't realise until the temperature reached something like 115deg, I forget exactly how high, but it was quite a lot!

Turning the heater on helped cool it down at the time.

But...my car was giving off LOTS of smoke a week or two after...this is the OLD video:


It looked white/grey but smelt oily so I've swapped the turbo and just started the car today.

It's much better now but I fear it may still be smoking a little bit more than it should.

I also saw drips of water coming from the downpipe (must be a small hole in it!) until it had got hot.

Smoke doesn't smell oily any more....and the garage isn't filled with smoke like it did

What are the chances the head gasket was fried last year?
