Looking for a source for the Cast Valley Covers that include fill Pipe and location for PCV setup. Mummert did used to sell them but out of Stock now. Anyone else know where I can buy one?

I don't FACEBOOK but I believe this is a source.

I think Blue Thunder sells one, not sure if finned or not. None are “dented” for the factory dual quad manifold but will fit all aftermarket ones.

I’ve bought the Mercury valve covers from Ace, and had them do a custom gauge casting. Great people to work with, nice stuff. The exchange rate is favorable, check it first for conversions to US$

Agree, Ace have them, I have one in the garage waiting to be put on.
They blank out where the PCV Valve goes, so you will need to drill it.

In regard to using a PCV valve, many of those aftermarket aluminum valley covers are not created equal. Regardless of the cover being used, it’s important that there is a baffle under the PCV valve to prevent oil from being sprayed directly on the valve. When looking at the aftermarket covers, the Mummert cover is one of the better designed covers out there in regard to a protective shield for the PCV valve to prevent excess oil from reaching the cover.

I just replaced the valley pan on my 57 Skyliner with a pan from a later model Y Block. Maybe from a 59,60,61 or 62. The underside of the pan looks like the photo from Ted. I will probably want to do the same for a recent purchase, a 56 Victoria.
Ok, this is my first post and please tell me if what I am posting is not correct. Thanks. Harold

My ACE valley cover came with the pvc hole and grommet; however, it did have a baffle for the PVC valve. ACE said that the baffle is excluded due to varying depths of the PVC valve. Upon my request, they did drill & tap the raised tabs on the back side for the attachment of a baffle. Rather than installing a baffle, I purchased a Moroso 68772 PVC grommet, which has an integral baffle. The Moroso PVC grommet doesn't have the tightest fit, but should be fine with a little RTV. I used a Microgard 2322 PVC valve that Ted had recommended.

And no photo? Block letters or script?
One thing about MERC for 1956 is that the OEM rocker cover colors/trim identified the HP RATING of the engine.

I would buy One of John's but He doesn't even show them on His Site as they are not available. Any Idea when He may get them?

I converted a regular Valley Pan to accept a PCV by using Moroso 68776 Grommet. Packaged as 2 to One Package. Fits a Hole 2.220 Diameter and .090-.100 thickness. Grommet has small Slot in Bottom to allow vapour to be drawn in but not Oil. When You find right Grommet at Auto Parts Store for your PCV it can be Super Glued inside the Moroso Grommet. I made my own PCV Valley Cover 4 Years ago and it works great. No excessive Oil Consumption. I would like to find a Cast Cover like the One Ted showed but so far no luck for Oil Fill Tube and PCV setup. Not sure how thick the Covers are that are available but this Grommet may work if not too thick. Moroso 68772 is same but pack of one. tk

Why is there a need to super glue the PVC valve into the grommet?

The PCV Grommet with PCV could pop out from Engine Vibration. Gluing it eliminates this possibility. No reason to leave Grommet loose in this Moroso Grommet. You can still pull PCV out to clean it or replace it.

Some years ago I used a Moroso baffle in the stock rear location on a finned cast aluminum’s valley pan. It was more of a duck bill design than the current one. While it worked pretty good on a stock engine, when I built a modified one it picked up oil. Specifically at 4500-5000 rpm making dyno pulls. That one was supercharged, and I blew 2 head gaskets in a row, both on #7. After the second one we really went looking and found oil in the #7 runner on the Blue Thunder intake. I suspected a high volume pressure oil pump and high rpm just threw more oil off the distributor gear than it could handle.
I welded a baffle like Mummert used and it never happened again. Since Moroso doesn’t show that baffle now, maybe that’s why. But for the race car guys making the long high rpm pulls at the end of the 1/4 mile, you might keep an eye on it.

I recall Ted's saying that the only baffle needed is one that prevents oil from directly splashing onto the PVC valve. However, as Mike stated, a high-performance engine that spends time at the track might have different requirements. Obviously, the engine he described is not going to be found in most of our vehicles.

Yes Hi-Po Engine would need a Baffle Type Cover. The Moroso Gromet has worked fine for Me with stock Motor. I want to replace the Cover with a Cast One because of Oil Leaks from the original Cover. When I take it apart again I want to fix Leak once and for all.

If the crankcase is pressurized as with a SC or TURBO, it is going to overrun a stock CCV or PCV SYSTEM.
Where was the vacuum signal source located?
That baffle is only a splash shield to prevent oil ingestion being thrown off the DIST DRIVE. It is not going to prevent oil mist ingestion by the PCV.
Study the original OEM design as to how oil ingestion was dealt with. A slotted piece of rubber isn't going to do it.
There is also a baffle attached to most OEM covers to divert air flow to the top of the cylinder heads for complete ventilation.
