So I'm trying to diagnose a bad idling problem with my '78 280slc and decided to check the cam timing. With the engine at TDC the intake cam lines up perfectly, but I'm not so sure about the exhaust cam. I don't know how precisely they should line up, so I took a picture. Do you think it needs an adjustment or is it ok? To me it looks a degree or two off.

Thanks.

PS: nevermind the oil buildup, this car had a rich running condition for quite a long time, but it's fixed now.

EDIT: please see post #3.
