I have no complaints with mine starting in the cold...and I still don't have a block heater installed. it chugs and farts a bit but its ALOT better than it has been in the previous winters, used to take me about 5 tries to get it to stay idling but now its 1 or 2 tries at most. I still have love for the 4D56. I change my timing belts when they are due...unlike phil!! hahahaha.
