I can feel it is loose a bit, but again as soon as I start turning the crank again it gets tight again. Is this normal?
If the checks for chain tension are being done under the right side cam sprocket (cylinders 1-4), then the chain towards the center of the engine (along the straight slide rail) will become tight when the crank is turned, and the chain outboards of the sprocket (along the tensioner rail) will be slack.
