I recently replaced my VCG because it was leaking and I was getting pools of oil around my spark plugs and in the crevices above it. I looked at the valve cover while it was off and didn't notice any cracks. Not even 1k miles after, I decided to check since I was working on the car and it's leaking again. Is it possible the cover is cracked in a spot hard to notice? I appear to be leaking somewhere between plugs 2-4, same place as my original leak. No codes or low oil warnings, no bolts were broken. Car has 44k on it and I also installed the RB PCV at the time of gasket replacement. Now is it just best practice to replace the whole valve cover at this point?

Nevermind.....found the culprit. Apparently it was cracked and I hadn't noticed it originally. But seriously....44k and the valve cover cracks....wtf.

As I have said before countless times, the Valve cover should be a service item every 40-50k just for the fact that the entire pcv system is built into it and majority of smoking problems is due to clogged pcv ports from a old cover

How much does it cost to replace the valve cover?

If you meant ECS, it's now $427 there now. I went to my buddy who owns Eurotek Tuning and he was able to get it for me for under $400. Gonna have to tackle this job again this weekend.

Got around to replacing the cover and here is the crack on the old one from the inside.
