I've been rounding up these 4 grommets/elbows for my own 403's and some of them weren't easy to find, until I discovered that NAPA Auto Parts had them all. So, this might help you if you ever go looking for them. I also found them at O'Reilly auto parts, as well as at NAPA. The HELP! grommets would be available whereever HELP! products are sold. I just happened to get them from O'Reilly. I will list the numbers I have for both HELP! and NAPA for the same grommet. The ones with the prices are the ones I bought, so they all were available as of today. I did not buy any elbows from NAPA, but I am listing the numbers here too. So, you could buy all of them from NAPA if you like. Interestingly, all the grommets were the same grommets, regardless of where I got them or the price.  

First one is the grommet for the pcv valve on the passenger side valve cover.
HELP! #42314 ($3.69 at O'Reilly auto parts)
NAPA, Balkamp #630-1364, $2.99
NAPA, Echlin #2-9118, (also CRB 29118), $4.49


Second one is the elbow that fits on top of the valve cover breather on the driver side.
HELP! #47034 ($4.99 at O'Reilly)
NAPA Balkamp #7351752
NAPA Balkamp #7351742


Third is the elbow that goes on the air cleaner base on the driver side.
HELP! #47039 ($4.99 at O'Reilly)
NAPA Balkamp #7351680
NAPA Balkamp #7351690


Last is the valve cover to breather grommet for the driver side. You only need one of these grommets, but I'm showing both sides of it here.
NAPA Balkamp #630-1074 (Box of 5). This was the best deal at only $2.99 for the box of 5.
NAPA Balkamp #630-1052. This is only 1 for $3.99

Thanks. I read on an Olds forum a complaint about the pcv valve grommet rubber being too stiff, making it hard to install. So my suggestion would be to warm it up with a hot air gun first, which would soften it up, and spray some wd40 on it.

I need to replace my PCV grommet again, not even on the road yet and the 3rd one that's cracked from new in a few years. I can't recall what brand but they are poor quality and the rubber starts to perish and crack. It has Taiwan molded on the base, does the HELP version also? I also know that it's a tight stretch for the PCV valve to fit, I tried 2 brands, and half the reason it eventually cracks. I found another alternative but at $20 each, they look crude even if the fit is good.

I have a set of 1970 Olds valve covers in storage, rusty gold. The grommet is hard, but not cracked anywhere, says something 43 years on.

I had no problem installing or removing them, though. Light machine oil, install upside down in opening, and turn, threads itself into the cutout.

Here's one. I used one similar to this that I got off ebay for a little over $2 back in the spring. I bought this one, the one that goes to breather element tube and grommet for driver side valve cover all at the same time. Have not had any issues with them yet. The ones I got were all Dorman products, which is who makes the Help products that we are talking about. Think these are about the only ones you can get today, they are all probably made overseas, unless you can find some NOS stuff. Here are links to the other 2.

I have 3 new ones here. One is the HELP brand, another a NAPA Echlin, and a NAPA Balkamp. They are all the same, with Taiwan and the number 314 on them. I've had one in my 403 for 2 years and don't see any deterioration yet, fingers crossed.

The GM part number is 385283. I looked at GMpartsdirect.com and they don't have it there. But you might could find one somewhere. For hard to find real GM parts, www.partsvoice.com works well. I just went there and it shows 6 places that have the grommet. Expect to pay more from these dealers though.

These grommets are for fitting to factory original Olds valve covers and air cleaners.

The MT's are probably meant to use some other aftermarket type of breather/filter that plugs in to its own size grommet. Might even be the same size as ones used on aftermarket Chevy valve covers.
