This is a junk yard engine that I'm putting into a Wrangler.

Look up and to the right of my broken oil pressure sensor.

I'm not sure what was originally in this hole, engine was already pulled - and I didn't see anything from the donor truck that looked like it went there?

 

i believe that's the EGR valve.

 

Yep. EGR Valve/tube/whathaveyou. Has the block off plate already. That engine out of a 96 by any chance? I think they stopped using the EGR system sometime in 96, but, still had manifolds with the provisions. My old one looks just like it.

 

Thats what I thought - but this image looks like the EGR mount location is blocked off. Here's Napa's picture of the EGR assembly.

 

Yeah, there is a plate bolted there instead. Mine is the exact same thing.

 

Yeah it is a 96. So was there a tube here at one time - that may have got removed with the exhaust?

 

Does that hole need to be blocked off or should there be a tube connected to it?

 

That hole originally went into the valve, the valve would open a port, to allow some exhaust gas into the plenum. The plate should be all that is necessary. Should be golden.

 

you are gonna want to plug that hole as well. That is the port for the exhaust to enter . I just had mine off to mod it ...I just bought a 3/4 plug and spun it in there . It will keep water/dirty air and debris from entering . cost is about $1 .
