Help with a couple Questions
 

Looking for a picture of the Vaccum lines diagram for 1995 90 cs Quattro.
My next question is what is the Spark plug gap for the 12v 2.8 V6.
Next question what size socket will fit the Oil Temp sesnor?
I have the vehicle up in air doing the oil pump strainer clean and discovered that the oil leak is coming from the sensor. If anyone can answer any of the following I would greatly appreciate it.
