Another pic with all 6 from the side (sort of). Best I have on me.
Looking more and more like that #6 cam lobe is done...
I was hoping to not pull the engine for a while.
It's always had a rough idle. I've seen videos of other 6's and mine just seemed rougher. Slight shake. I can pull the #6 plug wire and there's little change in how it idles.
At speed, however, it was always OK.
