I just had a random question involving sensor(s) coming from the heads of a carbed lg4. I took all that stuff off a very long time ago and when I come to put everything back together, there's one or two things i kinda forgot. I know the coolant temp sender is on the driver side, but a friend of mine, who had an f-body of the same year told me that the other side had a knock sensor, which i just might have in my hand right now... not sure.

So, i go out to the local pick n' pull, or at least what I thought it still was ( they made me leave my tools behind), and they tell me that if it's carbed it wouldn't have a knock sensor and if it did, it'd be on the side of the block (which also kinda makes sense).. my question is, where would this mystery sensor go? is it even from my camaro, or did it somehow make its way into the camaros' collection of random parts on accident?
the one on the left is already known, but the one next to it is a mystery..

 

can anyone tell me what this sensor is between # 6 and #8 spark plugs ?? Mine is falling apart and I dont know what is controls, this is on a 1987 IROC Z with the 305 TPI

 

haha, well i guess it won't really matter until I can figure out how to remove those plugs huh? They're square and LOOK like 3/8 but i have yet to find a ratchet in my collection that will fit it..

 

WTF are you talking about, the spark plugs or that sensor, because there is some sensor (cant remember what kind) that i took out of a friends Olds, and i had to go buy a special socket for it...nothing i had fit it and i got plenty of tools

oh BTW it looks like a CTS.......i wonder if it did get in there by accident, maybe your garage monster is playing tricks on you, he could of got tired of eating your 10mm sockets and wrenches i know my garage monster loves 10mm

 

Jut finished changing the plugs, no issue there but want to know what that sensor is between 6 & 8 , has 1 wire going to it and its broken

 

take out go to the auto parts store, compair it to the CTS, OPS, or Knock Sensor that they pull up on the computer.......thats my best advice w/o looking at it

 

It's just a plug that the company put in there where the coolant temp sender goes.. I couldn't get it off before i put on the heads, got pissed off an put them on anyways.. now I want to put it on, but I still can't find anything that fits into it.. I don't know, I emailed the company again, we'll see if they have any magic tricks for me... My problem was usually 9/16, i've misplaced a lot of those.

 

LOL well it looks like a 3/8 then it should be a 10mm, my garage monsters favorite food......if its not 10mm or 3/8 then heck if i know.......maybe one of them gator grip BS sockets may help, IF they work like they should

OHHH wait its a square recessed plug, like a pipe plug, i think there is actually a square head socket it different sizes for that crap.....hope you read this edit before you repost

 

if it weren't inverted i would have had no problem, but that's not the case.. I'm going to upload a picture as soon as i get it onto my wifes computer. hopefully i can get this off without taking the header off, because i really don't want to pull it..

 

look at my last post i did a edit oppps!!!!!!!!!!!

 

 

One on the left looks like the sensor for your temp gague on the dash (between #1 & #3 spark plugs). One on the right looks like a fan temp switch (between # 6 & #8 plugs). Neither is a knock sensor- they look totally different.

 

Okay, so the plug is actually closer to 5/16.. I did some testing with a rod i got from napa and it fit, sorta.. clearance makes it hard to be definative on that one.. Anyways, the rod is bend to hell now so i guess the plug won this round..

 

Okay, so i gave up on that again. It's only going to the gauge and the only consequence to this not being hooked up would be my lack of knowing how hot I'm running, correct? if so, I may just wait until it's tuned and painted and then just let a mechanic get pissed off at it. Or maybe the maintenance guys at my work..
