I was looking over the Hyundai Service website at the section outlining camshafts and valves on the 3.3L engine in the NF Sonata. I can see from the picture that it has seperate intake and exhaust cams, but I couldn't tell how many lobes they had. Do we have 12 or 24 valve engines?

It is a double overhead cam engine (2 cams per head, 4 cams total) with 4 valves per cylinder (2 intake, 2 exhaust) for a total of 24 valves. You will notice on the picture below that each cam has 6 lobes.

Thanks, the picture on my browser was so fuzzy, I couldn't count the lobes.

I have a new(used)17" LCD monitor. I still need to tune it up a bit for sharpness.
