Valve cover gaskets getting sucked up (updated, Pg. 3)

hey guys, well i have all the different types of welders there is, so no problems with welding things on.
I bent the bail spring in last night, and it is much tighter now, like on the old engine, so it felt a lot better putting it on. So hopefully this is a simple problem.
I took it out for a short drive today, only getting up to 50 mph for a short time though. I didn't want to test it to much, as our truck is in the shop right now haha

So.. We finally got our truck back which meant it was time for a free way test drive.
Sadly, after about 15 miles at 70mph it once again started to leak Sad

It did make it farther then previously tested, but it still leaked a lot. I emailed the previous owner of the engine, and he said he never had any problems with it leaking...

So, more thoughts? This is very frustrating

Weld on tabs

Did you try just buying new valve covers and bales instead of fighting with your old ones? I used to use the red Permatex RTV around both sides of the gaskets. The red one comes off cleanly when it's time to replace. I used a very small bead. Give it time to dry, and it should fix your problem WITH NEW COVERS. I'm not there to see your current covers, so I can't say what's going on with them. I think you said that you had a welder? Well have you tried to weld on the gasket retainers?

Any updates? I had to get towed home today for the same exact failure. Did the welded in tabs help?

I'm sorry, I resurrected this thread.
I'm working on a new motor now then I happened to find this thread.
I appreciate the ideas had been told here and interested in adding tabs on my own, but I was afraid if I would screw up head covers due to my poor welding skill.
So I decided bolt tabs instead.

Image may have been reduced in size. Click image to view fullscreen.

I made the height of tabs slightly below the surface of the gasket so the gasket will be sandwiched property even after it get squished.

I'm looking forward to seeing how these work.

Those rocker covers in the pictures are not stock - they do not have the locating groove for the bale spring in them. Whatever system holds them on is probably not providing enough pressure to squash the gasket onto the head.

Maybe getting a set of Bugpak black painted steel stock pattern covers and bale springs will cure the problem. And then play with drilling breathers in those covers.

I found on my setup that the rusty springs my engine came with were just too thin to press the gaskets down hard enough.

I had the same problem with my 1904. Anytime I got on it a little bit the gasket would get sucked up and I would spew oil everywhere. My fix was venting the valve covers, haven’t had a problem with it since then.
