Valve Question - BMW Forum

when I pulled off my valve cover on my 735i , I got under there and found that some of them were out of spec, but nothing to crazy, so I adjusted them. Anyway, after putting them all in spec .012 I believe is what my chilton's said, it still didn't get rid of the bit of valve clatter. Is the valve train on the M30 just noisy? It looked like everything was allright, no warped cam lobes or bad valves or anything, so is it just a little noisy?

I set them at .011 which helps with the clatter and will also boost performance a slight bit. It does make the idle a lil more rough and as you know these 3.5s dont idle all that well to begin with.

Good to know I'm not gonna suck a valve through or something. Yeah, it is a tad rough, but hey, what can you do?
