I'm also using the Canton thermostat and 1qt Accusump. Photos in my gallery, look for "
oil and coolant plumbing". The Accusump is mounted on the front cross brace and plumbs into a T on top of the
oil filter. The Accusump is used as a pre-oiler. The thermostat is mounted where a remote
oil filter mount would go on the front of the engine and plumbs into a standard sandwich plate.
I choose the Canton thermostat for the same reason as David, it's opening temp. Most of the others open aroun 180 and I don't feel that's high enough for the condensates and contaminants to boil off.
I can watch the oil temp gauge stop climbing when the thermostat opens although I'm in a relatively cool area (Oregon) it still gets pretty warm in the summer. In the cooler winter weather the oil temp never gets high enough to open the t-stat.
