PCV Valve troubles
I got a replacement PCV valve, pulled out the old one (was really hard). Now, putting the new one in should be simple right? Nope, it doesn't want to go all the way in.
There it is, not all the way in but it seems to be in the hole inside the grommet.
Does this thing go in at an angle? Or do I need to be more aggressive with how I work it in. I really don't want to risk pulling the grommet out and having it collapse and fall into the hole (don' want to cause more trouble). The grommet doesn't look damaged to me.

The PCV valve doesn't look like an OEM one, My original was a 90 deg valve. It must be bottoming out on the baffle. I bought an aluminum on that looks the same as OEM. You may want to find a different one.
I bought the summit racing one sum-440308 90 DEG.
Hope this helps some

hm thats weird, the old one that came out was the same one as the one thats in there right now.... maybe it was replaced before with the WRONG one. Still I wonder how they got it in there....

Those grommets got awfully hard over the years, but fortunately they are readily available.
Your local auto parts store ought to be able to order one, or you could get one on line.

I'm wondering if the previous owner stuck the other PCV valve so deep into the baffle, then needed to adjust the carb to try and compensate. Eric & Eric will know if this happens!!
That PCV is the alternative to the 90 deg. The hose isn't bent too much then collapsing with the vacuum is it?

At this point if the car was running good, I would do what Oldcutlass mentioned. Flush it out with fuel make sure it still rattles and reuse the old one. I've never tried it but I defiantly will with my aluminium one Ill be flushing it out this weekend. Saves a bit of $$

The first one, with the flat bottom, is the one that fits into the stock valve cover grommet.

This is likely your issue. The grommet is old you will likely just have to push the correct one in hard to get it in with the worst case scenario the grommet cracks in the process.

The rattle test is not the end all test for a PCV. Also you should get the exact replacement PCV for the application. Not all are the same. Even though one may fit and look the same they are not all equal. The spring and valve are different for each application. This can cause drivability problems such as too much crankcase bypass causing rough idle due to lean A/F mix.

Fixed it. Hooked up timing light and adjusted curb idle to 770rpm Park and 540-550 rpm D. The idle was a lot smoother. Also the line from the charcoal canister was unplugged, so I pushed that sucker in snugly.
I am using a duralast pcv1125DL valve.
