I have used the search feature extensively here and haven't been able to find an answer to this question. On my 360 LA build I am going to use the Mopar performance crinkle black cast aluminum valve covers. There will be baffles in them also.

I do not want to drill holes in them for PCV and breather for various reasons. My solution for a breather is on the passenger side (rear) run one of these twist-on breathers:

For the drivers side (front) I need to run a PCV. The PCV will be in the front because I am running an Edelbrock carb which has a front PCV port. Anyways I was trying to see if there was a grommet that would work in place of where the twist on oil cap goes, so I can just put a PCV valve in there. I could have sworn I saw a member here with pics of such a grommet and PCV valve setup.
I searched and searched, is this the correct one?

If that isn't, or if there isn't a grommet that will work in place of a twist-on cap for the PCV, I was going to get something like this:

I am hoping there is a grommet available for the twist-on spots. Thanks!
 
so...you want to run a PCV valve on one valve cover, a breather on the other and just pop that off to fill in the oil?


do those valve covers come predrilled?
when I got my cast aluminum valve covers I had to open the holes up myself
 
IF the valvecovers come predrilled the PCV you posted looks good

if not, just drill them however you want
 
The grommet that you linked to on Summit would work. BUT, I see they are extremely helpful in providing ID and OD measurements.

You might be able to find what you need at O'Riellys, I just took one of my M/T covers right into the store last week and fitted what I needed.

I have had one heck of a time getting the correct sizes, because a lot of places don't provide that info, just like the one in the Summit link.

The only way I felt comfortable in getting the correct ones was to do what I explained above.

It looks like this site has the dimensions. I don't have the valve cover here, so I can't check them personally. Do these dimensions look right?

Also I found the pic that another member has of the setup, this is what i'm looking to achieve:

One of the Mopar gromments worked on the PVC, but was too small on the breather, I recently ran into this issue and ended up slicing and dicing a gromment on the breather and still couldn't get it to work, thats when I decided to put in a PVC valve without the guts, making it open all the time, worked fine. I hope your covers dont leak, Im having issues on the back of each head leaking.
 
I was lucky I got grommets with my valve breather kit.I had to drill out(as cast Mopar valve covers)the holes and modify(trim) the grommets to work.
 
Did you find the right grommet for the oil cap twist on openning on those covers?
I am struggling with same search.. but only looking for breather .. not pcv.. but same deal.. grommet for twist hole on molar performance cover.. thanks.

Just buy the MP grommet kit for cast valve covers that goes in the cap holes.
The cast covers have to be notched for most intakes.

I run the twist on cap w/ the pcv valve in it, I also have run two of them at the same time . No grommits needed. What I`d like to see is a twist on cap w/ a breather tube to the air filter !
