I did the same thing on my TR3 a 20 years ago based on a tip from Bob Schaller’s booklet “More BS About Triumphs”. On the Morgan I turned down a ½“ long brass cylinder and put a 1/8” hole in the center of it. Worked great on the TR3. It prevents unnecessary recirculation when using a conventional thermostat instead of the sleeved type. Anyway, it worked on the Morgan (vary similar to the TR engine) until I discovered the fan belt was loose. I tightened the belt and bam! It blew out the gasket between the two thermostat housings when cold. I lapped the two thermostat housings, installed a new conventional thermostat and bam! It blew off the bypass hose. No matter how much I tightened the hose clamp it still leaks. I put on a new hose and it still dribbles.<o:p></o:p></span></font></p><p class=MsoNormal><font size=3 face=Calibri><span style='font-size:12.0pt'> Something tells me that the water pump is pumping too hard against the closed thermostat when the car is cold. I could spring for a $115 sleeved thermostat from Moss, but would rather continue using a modern conventional thermostat.<o:p></o:p></span></font></p><p class=MsoNormal><font size=3 face=Calibri><span style='font-size:12.0pt'> Anyone else have issues like this?
