Is it in the tube (elbow) that turns into the manifold behind and below the alternator, but above the water pump bypass hose?

And why couldn't it have been put on the valve cover vent tube like every other car on the road?

that should be it.

I dont know about every car having it on the valve cover. Maybe some 4-cylinders. My '87 bonne has it on the intake manifold as u described.
my '65 bonneville has it right by the intake manifold on the valley pan (push rod cover).

Then I must reallly be blind. Here is a pic of that side of the engine. There is two hoses you can see in the pic, but neither one has the pvc valve so I'm still at a loss.

Move all those plug wires out of the way right where the fuel rail wraps around the intake. That'* where the PCV valve is.

On my 90 SSE it is here



Move those wires out of the way and you can just see it in the picture.

this might help, also, though it'* a bit too far zoomed in for you to get the big picture. This image is with the valve removed.

Default location, location, location...

It'* pretty easy to see once you pull the rear spark plug wires out of the way and bend over the fender. It'* right there under the wire bundle running over to the EGR. There'* a wire clamp on the hose stub that connects to the intake. The top of the PCV valve has a plastic elbow connected to the stub of a hose.

I was able to get access to the PCV on my car, but could not get it loose from the manifold. Is it easier when the engine is warm? The last thing I wanted to do was destroy it in the process of removing the valve. What a PITA.

Of course, now that I fiddled with it, I am sure that it is introducing a slight vacuum leak. I couldn't pull it out, but it would spin in the grommet. Is there a good way to get it out?

Well just replaced mine. All I can say is whoever designed that location for it was missing a few screws upstairs for sure.

I don't know if I was lucky or not, but it came out and back in with little hassle. The biggest pain was working around all those wires. I can say through I just came back from the store so the engine was hot (you can tell by the burn mark on my nuckle) so that might be why it came out so easy. I'd say try with the car warm and see if that helps.

^ and hope to hell that the valve doesn't break up when you remove it :(





(oh well, it led to a few hours of labour and a somewhat needed fresh intake gasket)
