I need a pick of a 1985-1986 190E 2.3 8 valve's head where the sensors are in the front of the head near the Thermostat! What I am looking for is how the vacum lines are routed for the Timing advance vacum lines on the red sensor! One line feeding the sensor on mine goes to the intake port for vacum feed. The other side has two lines on it, one to the vacum advance on the distributor and the other over to the fender area for the Charcoal canister in the fender! The MB Maint CD shows that there should be a valve in there to stop vacum I guess from flowing both ways to the fender. When the sensor is closed under 50 degrees, vacum from the canister is supposed to feed the advance with a reducer in the line, but I do not have the valve or reducer in my line. So if someone could help a brother out I would be so darn happy.....
