Valve cover leaking... Again...

Here's the scoop.

I got my 530xi late 2014. I did a bunch of maintenece to it, includong the valve cover gasket with a small amount of rtv silicone to keep it shut. The gasket I took off looked new, despite the fact it was leaking.

Now it's leaking again. I know the gasket itself is fine. It's just over 2 years old and bought from BMW.

Has anyone experienced a warped valve cover? I'm thinking of finding a place that will machine it flat and see if that fixes it. Nothing is visibly wrong with it but i suspect there's a few tiny gaps.

I have a Renz branded gasket which I have yet to install. I was considering using a trick that diesel mechanic showed me which is to coat both sides of the gasket with high temperature RTV silicone. Do one side first and stick it onto the cover. Let that set up, then do the other side and assemble it after it sets up as well.

Seems to me it is cracked. Perhaps not enough to see when cold and with it off and in your hands. Or it is leaking from valvtronic motor gasket and you 'think' it is the valve cover?

Funny, I JUST spoke with my mechanic about it 10 minutes ago. I dropped car off for oil change and inspection and few things came up, one of the valve cover gasket. He said that with that, you should really replace actual cover as well. ( https://www.ecstuning.com/b-genuine-...ZxkaAs3k8P8HAQ ). He said exactly what is happening to you. People replace just the gasket and then they are back to the shop because they didn't replace the actual cover.

Hmmm.. But for $400, f that. It's barely a problem. I just like my engine bay clean, and it's dripping on an O2 sensor wire. I wonder how much it'd cost to get milled flat.

I don't think it's cracked or anything.

Yeah, it is expensive. That's why my guy told me, if I am planning to keep the car for longer than 2 years, then it would be a good idea to change it all. He said mine is not bad YET. He just told me to look out for oil burning smell through the vents and if I notice it, then it's time to change it. I will probably do it myself since the quote was like 900 bucks.
