1997 Olds 88 - I want to put my new PVC valve in , 100K miles on it.
here is a photo I grid marked, please tell me where I should start digging to find the PCV. I suspect it may be hidden under something else too.
You can pinpoint it with tenths if u want eg: C4 (where C crosses 4 ) or B.3 x 4.5 (where B and a third crosses 4 and a half)
Hope I am at the correct end of the block ....... thanks.
Between 2 & 3. That thing thats rasied up in the air with the connector has to be removed. The PCV is under there in a recesss.

Can you supply a picture of the entire engine?
I believe you are at the wrong end of the intake manifold, from what I can tell from the info I have it's at the other end, drive belt end.
I also found this on the internet:
on a 3800 eng. take the eng. cover off and on the top left of the upper intake its under the the grey sensor
ok, here is the alternator, pumps and pulley end of the crank. ( front of motor )
Yes,I thought this had the electronic, pcm controlled pcv, no real maintenance here.
The device in B-C/3-4, remove it very carefully, the PCV is underneath. Pay close attention to the O-rings and where they go.
Ok, will watch the O rings. tnx
Amen....one of our techs recently changed the upper manifold on one of these engines. After he changed it, it developed a funny whistling noise. You probably know what happened.
He ended up tearing the engine out of the car and stripping it down looking for the problem. He never asked anyone in the shop for some advice. I wandered over after a bit and asked him what the problem was. He told me his little story and what he'd replaced. He was pretty upset when I went straight to the pcv valve location and pointed out the o-ring that he'd forgotten to re-install into the new manifold.
This is probably why Dorman is shipping their replacement upper plenums with the PCV valve already installed.
Some days, I really miss working in a dealership... ;-)
