4.9 EFI - Valve cover
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.
