Removed Thermostat ( An Experiment )
I've been curious about this for a while and read all the arguments about why it will not work but had to try it for my self. As some of you know, the PTE modified thermostat for the v12tt does not work and so no one I know with a v12tt has a 160 t-stat.
I live in the south and the weather has finally warmed up to the 80's and figured now is a good time. I pulled out the thermostat today and drove the car around for a while. Here is what I observed.
-Coolant temps moved up slowly until they got to about 78 C (172 F) but that was at idle.
-Coolant temps stayed around 70 C ( 158 F ) while driving at 25-40mph. I did not get a chance to get on the freeway
-No CEL
-Left exhaust pipe had a lot of white smoke right from the start but right pipe was fine. Anyone thinking its a head gasket can forget it. The white smoke was there within 30 sec. of starting and water temps were very low.
-Because of that I parked it and did not get a chance to drive it more.
-I have not put back the t-stat yet. Want to play with it a little more.
Any thoughts as to what might have happened?

I put back the t-stat and reset the adaptive learning (referred to as ecu reset by may) and all is well. Cant explain what the white smoke was??
I'll try to keep those of you with v12tt posted on this project. The thermostat is very different than any I have seen. I'm thinking of swapping out the wax pellet chamber from a 160 stat (one with similiar dimensions) and swapping it into this t-stat but I need to be careful not to damage the oe t-stat because I dont think u can just buy it by itself. I think it comes with the housing only.
