Hi Grumpy, have had camshaft in both side of motor and there is a little movement but i am sure once the motor is reassembled it wont be there, have found roughly same amout of movement on other motors. The first two photos are the top of camshaft and internal of motor were camshaft fits. The next two photos are bottom of camshaft and bottom of sump were camshaft fits. Now some photos of pushrods, rocker arms etc. Please note inlet peices are on left hand side of photos.
