Hi "tiger0529"
I agree, there is something very beautiful about Alfa's... and yes, my 164 is a UK model. Thanks for the tip regarding parts compatibility with the 155 TS 8V, I will keep that in mind.
I think overall the my Alfa is sound, although it does need a service which I will be doing this weekend.
My main concern is that oil is weeping from the rear of the engine and it's a bit of a mess back there. I don't think the head gasket has blown, there is no mayo around the oil filler cap or dip stick and the engine temperature seems normal and steady. But, the coolant in the reserve bottle is sort of brown and milky, so perhaps I should be worried...

.... I don't know.
I have read postings regarding a retorque of the head bolts, something I have never tried, although with guidance I would try.
Anyway, grateful for any tips and feedback.
Neale
