Next engine you do an engine with Indy covers try a set of the Cometic rubber coated steel gaskets. The Cometic gaskets are a step or two better than the Moroso gaskets. I've thrown all my Moroso gaskets away and switched all of my engines over to the Cometic gaskets. Zero leaks even after having the covers on and off a bunch. And the Cometic gaskets will hold a bunch of pan vacuum.

With a nice clean engine compartment like that you should consider tossing the MP valve covers and getting some nice billet covers. Not sheet metal covers, billet ones. Like these:

Dave......you do have some breathers on the motor, right?

Andy.....what's interesting on the mp cast covers is.......they seem to work just fine on stock heads with the normal Fel-Pro cork gaskets.
I just silicone the gasket to the v/c, and I have been able to R&R the v/c's numerous times.....no leaks at all.

Yes. Using breathers

Very high tech and what's more,,,very pretty. My wife might even let me set this in the living room.

You need to check the valve cover with a straight edge,if they ain't flat and you can't make them flat,then you need the 1/2 inch thick gaskets so you have room to crush,,,,,,don't ask how I know

Boy has this thread gone off the rails.....

MoparDave has a tech question about one of my products and I come on here to assist him in resolving the issue and diverts to Mopar Performance valve covers, this brand gasket, that brand gasket, pimping billet valve covers, etc..

When someone purchases from Superformance Products they get real, honest and cohesive tech support direct from the manufacturer. Take advantage of that benefit.

Posting an issue on a web forum muddies the water with expert "opinions" and can take hours or even days with back and forth questions and answers when a 5 minute phone call can get someone on track. I simply can not sit here and monitor moparts for everything that goes on or every question that may arise, it's just a side benefit that I'm a member who enjoys the hobby and willing to help where and when I can.

Dave, call me @ 866-925-78 five five and lets get the answers to your questions handled!

Thanks for your support

I myself who too has experienced leaks of uncertain origin have learned points from this thread which may prove of value in the determination of the cause of my own valve cover sealing issue.

If Dave had merely called your firm instead of using this forum for advice, which all agree is a valuable tool, I and others would not have benefited from the shared wisdom of fellow members.

Would you not all agree that this would be a a primary purpose for the existence of this forum?

Just the nature of the beast Greg.

Same red gaskets on my Mopar Peformance covers on RPM heads for about 7+ years and no leaks..............

Sorry Greg . not knocking your product just curious to if any one else with the issue as i thought it might be common with the gasket as stiff as it is. Using your gaskets in the rest of the build as well. Great product. Thanks to your rear main seal and Monty Smith advising me to clock that seal 12 and 6 oklock. No leaks there or any where else. Havent measured everything yet but will in a few. I just think a soft gasket might seal these covers. if i could afford $600 covers i would of bought them.

Personally, I don't think this thread got off the rails. Although, that does happen a lot around here. The OP asked a question of the members and the answers have been relatively on target.

I like and use Superformance gaskets.....in certain places. They are the ONLY thing that I have found that can stop my intake from sucking oil. But their valve cover gaskets leaked on my Hemi. Fel Pros stopped the leaks. I think because they were softer. Plus they are a lot cheaper.

I do have to torque them occasionally. And I change them when I adjust the valves. Works out to about $15 a year. But the oil stays in the engine now.

Just my .

No reason to be sorry and I know you are not knocking anything, just need a little bit of help and I'm more than willing to give it. Just give me a call.

It's just much easier and more productive to have a conversation over the phone than go through every little technical detail that may or may not be pertinent to you while pecking away at a keyboard while others take the conversation off into la la land.

For those injecting the greatness of the 1612 (made of pulp fiber aka paper) I'd guess have never seen or used our Carbon-X that have been out for 4 years this month and have become very very popular.

Getting the covers off now. Let me get a hard look at the flanges and ill call.

Carbon-X is what I used on mine with the Indy no logo covers and dry as a bone.

Once you tighten em up a couple of times, you'll notice they will need to go back on into the same impregnation they made to seal and you can feel it when it's right........

Finally got around to putting a straight edge on the flanges of my covers. sure enough they are low in the center of the cover, high on the ends. looks like about 1/16" difference. Gonna have to use some black RTV and glue them to the covers. That should fix the leak. I would have thought tightening them up would flatten them out to seal. guess not.

I always silicone em to the covers no matter what material and that cut's you chance of a leak by 50%............

Glue the Superformance to it. They will seal to the head just fine!

These are too oily at this point. I ordered some inexpensive mr.gasket 1/4" off ebay. should of been here before holiday, but just got them. look like cork painted black. thought they were rubber. Gonna see if these will work. I glue'd them on covers last night. Will call Greg later today to see what my other options are. Thanks
