No more Holley valve covers

After the PCV issue I had with the Holley valve covers I took them off and sold them. I powder coated my stock valve covers krinkle mat black and my coil mounts metallic silver. Here are the results. Sorry for the one pic at a time,
I'm doing this off of my phone.

May I ask, what kind of issue did you have with the Holley value covers that you had. I brought the same ones, just haven't got around to install them. I see you have a supercharger, I don't, will I have the same issue. You can PM me, if you don't want to post it up on the forum. Thx!

Please disregard my last post, I just came across your post regarding the issue that you had with them. The value covers did look badass on your car. Now I got to make the decision if I want to install them, along with the inline filter on my car.

Like Vann said above, could you elaborate on what issues you were having? I have Holley valve covers on my car now.

Mike, I have an extra polished set of Holley covers that I'll make someone a heck of a deal on them.

I run holleys on my car. Zero issues. Several friends with 1000+hp cars run them, also zero issues. I would recommend them. Great looking and priced well. If you are having PCV issues I don't think it is the valve covers fault.

I'm running the Holley covers on mine (w/supercharger), no issues. The 'black crinkle' looks good with what I have under the hood.

So, if you had a problem with them, why would you sell something defective? Your ad made no mention of a problem with them only that you were doing some spring cleaning.

Looks great! Holley's baffle allows oil to sling off the rockers up into it where the oil is then sucked out the vent....not a good design. They are fine if used on a LS3 style valley cover where the PCV vent on the valve cover is not used.

Holleys have the same shield/baffle as stock covers. They work fine. Plenty of people use them with zero issues.

I was having the oil sling/catch can filling up issue with the Holley's as well. The baffles in the holley are the same as what was used in the 1st design GM valve covers. GM changed the driver baffle in 2/2011.
See my post here:
http://www.camaro5.com/forums/showth...y+valve+covers post 8.

I have fixed my issue with a different routing of the PCV to the catch can and this fixed the issue of over filling. Many miles later with the Holley Covers and normal draining of the catch cans. Also the inlet of the whipple looks clean and free of oil.

I took the catch can off mine. My car never uses any oil between changes and I was getting 3oz or so every 5k miles in the catch can.

My buddy was having a lot of issues with his. Just so happens he also blew his rear main while they were on. Needless to say he took them off.

Rear main seal blowing out is from not enough vent. A lot of catch cans are made for looks, not actual performance and can't flow enough for boosted applications, which leads to popping rear mains. That is why a quality vent setup is important, because replacing a rear main isn't fun.

Holley valve covers breath great. Probably have another 6k miles on mine since this thread was started. 1200+rwhp, no oil blow by, no issues, they work great. Sounds like a lot of people are not installing something correctly or have a crappy PCV setup for their application.

Reading is fundamental

I, like most men, fail to read the instructions when installing things. There's a note that states you'll need to add a PCV valve with part numbers. My catch can was filling up ridiculously fast. But after some research on C5, I noticed that I was an idiot for not reading the install sheet first. I picked up the Fram PCV valve for about $3 at Advance Auto.
