Ultimate valve cover gasket, what brand and p/n??

Just found my cover gasket is leaking again (258 I6), and it is because I have to constantly retighten all the jolts and it has squashed out again like the last one. Is there one out there that has the metal rings in each hole to give the bolt something to actually tighten down against? I know I can use silicone or locktite, but I want a quality gasket in there... I hate silicone messes.

Both Victor Reniz and Felpro have one piece rubber gaskets that are steel reinforced about $45.

the valve cover bolts have a pretty low torque value (can't remember the # but should be in the manual) so if you're having to tighten them more to try to stop leakage then i'd suspect something wrong with the installation like valve cover sealing surface isn't flat, sealing surfaces not cleaned, allowing sealant (if used) to properly cure, valve cover bolt threads and head threads not clean (to get proper torque), etc. Also, over-tightening them will cause the gasket to squish out of the sealing surface (causing leaks) and could deform the valve cover sealing surface.
Some folks swear by the cork gaskets & others use the more expensive ones so it seems all work if properly installed.

George, do you have a p/n for those? I got a FelPro one and it was just the cork, no reinforcements.

When I first installed it, it sealed great. I had no leaks for about a year. My only issue was the bolts kept backing out so it eventually smashed the gasket front needed retorqued so much. Every time you retourque it, it squeezed it a little more...

Victor Reniz gaskets (Dana Corp) 15-35443-01 @ Car Quest
Felpro has one also I know I installed it on my Jeep though I like the Victor Reniz better

I used the felpro and it was like $50. No leaks yet but it's only been about 6 months

Looked at NAPA, Auto Zone, Advance Auto, and O'Reilly... and even Summit Racing. None offer Victor Reinz?! And all they show for FelPro is the $7-12 gaskets. There isn't any more Car Quest stores around here, they've all closed up.

Looks like I'll be searching online now. Thinking I'll be doing the valve seals while I'm in there, as it has been puffing smoke pretty bad on startup the last month or two. Strange, as it just started doing it one day. I think a seal may have actually cracked or something...

I used Fel-Pro.

Torque spec on VC bolts is 4.58 ft/lb (55 in/lb)

Your flange is probably all tweaked to hell from repeated tightening.
Try straightening it out with a hammer and piece of steel.

Short of that get a new cover and torque the bolts only to spec. No more.

Been there. Once a cover is goobered up, they are TOUGH to get to seal again....

Yeah, I straightened it up the last time when I put the recently failed gasket on. I'm thinking instead of the $50 for these gaskets, I'm going to clean out the holes the best I can and just use blue locktite on the bolts. I just hate to do that, but I also don't see spending $50 the more I think about it since this engine is only going to be in there (hopefully) only another year...

I believe I also used Great Stuff to seal it.

Had a bear of a time with mine, but now that is about the only thing that DOESN'T leak.....

Make sure you have the correct PCV valve and that it's not gummed up.
High pos. c'case pressure will blow out a valve cover gasket.
I used RTV hi-temp silicon sealer(orange)and never have had an issue.
