Looks like Im missing something on my transplant... its a 91 302 out of a f150... I thought I grabbed all hoses and everything but apparently Im missing this... its on the back of the engine, behind the intake, but down low towards the tranny.... sorry bout the pic its hard to get to standing on a ladder holding a flashlight in one hand and a phone in the other trying to balance... right behind the red wire...


the hole is about 1/2" Id say, looks like vacuum/emissions er something... I just need to know what it is and what it goes to.... im gettin pretty close to starting it for the first time and dont want to throw any extra codes for me to deal with...

Knock sensor hole. Should be in the block, behind the passenger side of the intake, on a flat surface of the block, near the tranny but on the engine block.

Better pic will confirm.......

Here is a pic of the back of the lower intake for a 5.0. Is that the hole you are reffering to in the back there? If so that is where the PVC valve goes in and the pvc hose connects to it.
I was thinking that at first too, but I think its in the valve cover on non gt40 engines.

its the part that has the FORD label on it, it sit on top of what I would call an equalizer tube that seems to be connected to the back of the heads...



here is a pic before installation, its on the far left, the black strap seems to be wrapped around it..

Its part of the thermactor system. There should be a hose going from the smog pump to that. If the electrical stuff for it is hooked up there wont be any codes.
