160 therostat vrs 195. And Heat soak Check engine Issues.

[Phman9]

When I first heard the noise I thought it was the torque bolts. No signs of damage and the bolts were tight. One day I was filling up gas and a guy came up to me and said that noise was my water pump. That is when I replaced the 160t with a 195. It was not the water pump. I spent some time with an electronic stethoscope and located the noise to the middle of the lower end. I am fixing the po202 issue and going to trade or sell it off forever.
