Next question: With the 964/993-style sensor locations, how does the oiling system prevent that whole ex-thermostat hole from becoming a giant air bubble?
On a cold start, that entire hole is empty, right? Just air in there? How does that air get displaced with oil given that the high point where the sensors are mounted is above the "drain"? Basic physics tells me that the hole would fill with oil only up to the uppermost hole, at which point the air would just compress - it's got nowhere to go. At this point, the pressure sensor would be getting an incorrect reading (air pressure vs oil pressure), the temp sensor would be reading air temp, not oil temp since it's not submerged... Just doesn't seem right. Made a little diagram to try and explain what I'm talking about, not sure if I am asking the question right. Blue = air, red = oil.
