While taking the fuel rail off, I found a O-ring missing on the # 8 cylinder. I replaced to O-ring, put the intake manifold back on and problem solved. One more thing to check before you put everything back together if you choose to remove the fuel rail. Hope this helps.

I have done this job 7 times on 545s, 645s and 745s. This was the first time I ran into this problem so, I thought I would post it to help some out.



Thanks for adding this. I'm overseas but my home is in Columbus, Ga.....right down the road from you. If I wait to do this stateside i'll send you some more business with my car.


All time best DIY write-up I have seen.
