Engine Tech Question
Im in the process of changing my camshaft and removing the cylinder heads.
With the fan belt removed I noticed that when I turn the crankshaft via the crankshaft pulley bolt there is slack or what seems to be excessive clearance at the pulley. I can turn the crankshaft a couple of millmetres in either direction before tension is taken up and the engine begins to move the pushrods.
Not sure if this is normal, this problem is not noticeable when the rockers were removed. ( when theres no compression )
This makes me think the keyway is OK and that it could be related to the way the gear drive is operating.
Has anyone seen this before?
