Ok, now i'm seriously confused. To my knowledge i have an rb30e block. Series two. Bought it out of a car. It has one sensor (electical plug) screwed it between cyl. 5 & 6 on the drivers side (towards the back).
There are three holes just below the top of the block (~60mm down), and are ~150mm apart. They are tapped, but only go into the block then stop.(sorry, never removed a knock sensor b4). One is above the right engine mount, the sencond is above the oil fliter, the third is 150mm back.
What i thought was the knock sensor is between the last two.
Am i right? Are these holes the positions for knock sensors, if so what is the plug by itself?
Can any 1 take photos?
sorry for the questions, just wanna learn
