Good job. You reminded me about when I did this as well. I'll have to put up pics from my n62 4.8is.

Those valves were $14 from ecstunning, BMW brand. Just thought I let you know.

that is a lot of cheese. I heard that those valves, the rubber part rips, making ripping sounds. Dunno, mine never did that, I just replaced because it was very cheap.

I too had a bit of cheese. But a fraction of yours. Car came from Florida, so that explains it.

How many miles on yours?
