I bought this 1988 F250 with all the air polution stuff out of it. I would like to know what goes in the hole on the REAR of the valve cover. I have a PVC and hose going from the fron hole from the FRONT of the valve cover to the intake - but I would like to know what goes in the REAR hole, as I have smoke coming out of it now - and the smell is finding it's way in the cab. Does a pipe, tube or hose connect there to something else?
Thanks so much.

 

the EGR goes to the rear hole in the valve cover. the hole in the frnt is for the breather assembly that goes to the intake box.

 

I think you mean PCV valve and not EGR.

 

whoops, lol
