This will sound really stupid, but I didn't start this project. My son took this apart and he doesn't remember what goes where - his first engine project.

We're installing a rebuilt 302/5.0. On the intake manifold, driver's side, there is a threaded hole (opposite the EGR tube) into the exhaust crossover area. Center of the manifold, just above the injectors. 1/2"NC bolt starts to thread into it, but I didn't push it - it could be pipe thread I suppose.

What is supposed to go in here? Any pointers are greatly appreciated. Ask if you need more info or pics. Thanks - Tim

ps. thot I'd ask in this forum 'cause I think it's more truck system specific than engine.........

 

Photo Please, Just rebuilt my 5.0L EFI

 

Probably the knock sensor. I'm not sure all trucks have them though...

 

Thanks guys - picture gallery has been set up with a picture of the questionable orifice - lighting was terrible and camera is an old digital - hope this helps.

Knock Sensor, find the wire that goes with it, as its a one wire plugin with a cap attached to it. It senses the knock from the engine and if not adjusted correctly...could make the engine stumble upon acceleration.

 

That makes sense - thanks, I owe you one.
