I hope you all had a great Thanksgiving. I took the day off from work NOT to shop on this Black Friday, but to tune the 1991 NA Series I Orphan Olds up. I replaced Everything(Plugs, Wires, O2, Gas and Air Filters) but I CANNOT find where the old PCV is located. I thought it was somewhere underneath the Alternator but I can't see where it is. Can you offer a little assistance. Thanks again.

Not Underneath the alternator, but very close to it. Its on that side of the motor, and if you look you will see a black "cap" looking thing right on top / to the left of the intake. Unscrew it (1/2 turn counter-clockwise) and then you will be able to pull it out. The PCV sits inside. If you still cant find it let me know and I'll run out and take a pic.

Later!

Thanks for the tip. I'll go out and try to discover it tomorrow. I'll let you know of my progress.

I think you have a Vin C engine. That valve is a little more difficult to replace. It'* in the intake manifold, and it looks like an L-shaped piece with a rubber tube attached to the top of it.

Take the plastic cover off and look on the top left (I think) of the engine. This one'* tough to get to. I replaced one once and it took me a while to get it out.

Ahhh, good point. I guess I shoulda asked what motor we were looking at here first. I assumed 3800 Series II (or Series I should be close too). As far as a Vin C motor, I have no clue, and you can probably scratch my advice since it will be different.

Later!

Hi Guys, I didn't have a chance to look for the PCV this past weekend. YES, I have a VIN "C" engine. If you could give me some additional direction I would appreciate it. Would it be easier to swing the alternator up to find/get to the PCV? Are there any "Surgical" tools that you would recommend when performing this operation to make the job easier? The Delco PCV(#CV899C) IS "L" shaped. Aprox 1/4" tube connects the bottom black plastic and approx 3/8" tube connects to the top green metal can.

You know, I don't have that engine anymore. I remember it was on top, and you have to take the cover off. Then move the metal hose clamp off of the rubber tube, using pliers. It was kind of an awkward piece to get out. The manual shows it just to the left of the "3" on the intake manifold.

Thanks *Fuddy*. I'll keep up the hunt for that fabled PCV this weekend when the temperature gets above freezing here in North Jersey. You don't hear this part failing too often, which is probably a good reason why PCV'* do not receive much *press* around here or anywhere else. I can give anyone that has this Series I engine some advise when removing the plastic cover in the cold. Make sure you warm the engine up before you attempt to remove the cover. And after you remove the cover, keep it in a warm place. If you don't, you risk of breaking the plastic clip that holds the cover onto the fuel rail. So be careful this winter when removing/replacing that cover. There!!! I actually feel like I contributed something to this *organization*!
