No, he did it simple way, and then we lifted the car and found some fresh UV residue from bell housing.
Once again in order this cooling system to work properly it has to be 100% leak free, otherwise there isn't enough pressure or flow to open tstat....
Now at 3000 rpm tstat opens completely so lower hose is 65C and temp is at 93C idling is at 98-99. So lower tstat won't solve the problem bc even if temp is lower at wp it doesn't mean that cooling is effective and heads are being cooled like they should.
Valley pan, rear plate, coolant pipe are the most important things in this system.....
Straight six has nothing like coolant pipe seals or plates: everything is integrated in the block, so it never has issues with low pressure.
