Well, as I stated before, I am just the wrench on this project . Although I gave advice on most of the build, some things were out of my power, like chrome waternecks
....
The thermostat did not fit will into the recessed area, which is probably why most of these have problems. I had to file down the outer diameter of the thermostat itself to get it to fit snugh inside the housing. Unless the waterneck itself breaks down from corrosion, I don't anticipate any leaks.
