i was wandering if anyone could tell me what sensor is right under the heater hoses on the back of the intake manifold and maybe post a picture i have coolant leaking either on it or out of it not for sure.

also has anyone noticed that something hits the bottom of the lower intake manifold i am going to be taking it off this weekend to find out and doing my oil pan gasket at the same time.

 

there arent any.....the pcv valve is in the center of lower, nothing else is attached. there is a "y" pipe that goes for the smog system. but no other sensor



my guess is thats coming from the egr



i dont even know what u mean..... the black tube can bump if you have some vac tubing out of whack... but im not even on the same planet on this question. too broad homie

 

i noticed the other day that when i put a steliscope to the lower intake something is hitting the bottom of it i just needed to know if this is normal or what might be the problem. oh and the noise is coming on the driver side front of the lower manifold were the lifters might be but will know for sure this weekend

it is defently not the pcv and egr has no coolant running threw it

 

gonna have to post a pic. there shouldnt be any sensors at the rear of the intake manifold

 

ok so i now know it is not a sensor it has a hose going to it that connects to the coolant line on the intake

 

i also need to know where the canister purge solenod is i am getting a check engine light for this
