I am doing a head gasket on my 1979 Alfetta Sprint Veloce, and I noticed an odd thing, most likely the effect of previous maintenance. The #3 cam bearing cap (rearmost exhaust side) seems to me to be installed in the wrong orientation. Both the numeral "3" and the groove on the cap are on the opposite side compared to the other two caps of this camshaft. I have not been hearing any strange noises coming from the head, but then again this car is new to me, so I cannot claim to have much experience with the sounds of this engine. Any suggestions as to whether to leave this alone or put it back the right way?
