I have a 96 4 door 4wd blazer that I that I replaced the engine in with an engine from a 98 2door 4wd. The truck and the replacement motor ended up sitting the better part of a year and a half and I ended up replacing the fuel and water pumps up instaling the new motor. Can anyone tell me where the vacuum hose from the pcv goes? the motor has a slight lope and cylinder number 5 seems to be running lean..but I cant find where this hose goes and i want it to be completely right so I can eliminate the injector poppet as a problem for that cylinder. also its start a little ruff but isnt throwing any codes.

 

This should help:

 

not quite from that pic I cant see the vacuum hose off the pcv assembly..I need something that shows how that assembly and the vacuum ball are connected

 

That image shows the entire PCV line from the PCV valve in the bank 1 valve cover to where it connects to the upper plenum.

As far as the vacuum ball is concerned, that is a completely new question that was not asked in the original post. But they connect at the same location. It is a 1/4 turn (IIRC) fitting that fits into the plastic upper plenum.

Here is the best image I could find on short notice of the actual plenum marked up to clarify...

 

swartllk i am having an issue trying to find out what that piece in ur picture is called cause its not the pcv the pcv comes off a hose or pipe that is on that top nipple and goes into the valve cover any ideas the name of that piece that goes into the upper plenum?

 

Since you already have a thread asking about this, lets keep the discussion there.
