i broke what i think is a knock sensor its about 3 inchs tall and black plastic
it broke when i was taking off the intake it sits right behind the block agaisnt the firewall

any help would be nice
im doing a heads and cam swap

 

Knock sensors are under the intake. I think you're talking about the map sensor.

 

no its not attached the the intake its behind the intake and i goes in the back of the block

 

I think thats the oil sensor... it use to cost about 45 bucks. You can pick that up at your nearest dealer. Itll be easy to screw out since you already broke it.

 

yes, its the oil sensor, the short one besaide it is your cam sensor, ithe map sensor is on the back of the intake, the knock sensors are under the valley pan,
