well give me a little credit
Car is a 1987 300D-T 235,000 mi, about 65k since engine rebuild.
Gauge was teed off the switchover valve line, in place of it incase the valve itself was bad (pretty sure its close to getting clogged). Had already pulled the pressure switch and "hose barb" from the intake and cleaned them out, as well as the the vacuum lines, which I had previously replaced due to rotted connections. Intake is already scheduled to be coming off when i find free time to be cleaned, and replace leaking seals and gaskets.
Conditions observed: 30's outside today, 2.5 mile drive to McDonalds, all the way there 10 psi, temp gauge was at about 60 C when I got there. Shut it off, went inside, picked up food, got back in and drove home, temp gauge at 80 C. 6psi all the way back. Not the first time I've noticed this, does it every time it starts when its cold.
Vehicle Speed: 60mph~
Engine Speed: ~3,000 - 4,600rpm
Right Foot: Pedal on Floor
