Addressing leaks on back of engine - Camshaft covers
I've seen a few threads allude to the camshaft cover caps and it seems like a logical enough place to start with cleaning and replacing. I'm putting in an order with FCP Euro but isn't clear which part numbers for all three. Can anyone chare the p/n to use?

I don't have handy the part numbers, but I can tell you my experience: The quality is hit or miss. My solution was to buy some generic, I think Dorman, and install them with Permatex Black. Clean the openings carefully first. Apply the sealant to the plug, not the opening, so the excess gets pushed out, not in. Let sit for a day.
No leaks and it's been 40k miles.
The plugs are a horrid design. Nothing holds them in besides friction, and the valve covers expand and contract. Plus, they hold back oil, as we all know. It's nuts.
I have not tried to remove my plugs since installing; it might have to be destructive, but in my experience Permatex Black does not stick all that well to aluminum.
