Loose oil cap problems on an LS3 I have an LS3 with the style of valve cover where the cap fits directly on the valve cover with no neck. The cap has fit very lose since the motor was new and I get some oil leaking out when I run on the road course. Is there a special brand or style of cap that fits better or can I use a larger O ring with the cap? Since it uses the single **** in the valve cover hole rather than threads to hold the cap in I don't see it ever fitting all that tightly?

Have you found a good solution for this? I have the same issue and I originally tried this cap from Amazon:
It worked great for about a month and now it is loose also. Unlike the original cap it has a lip to hold it in place and it won't totally pop off but there is oil seeping by and dripping onto the header.
