Question on backing the rocker arms off.
I was watching a friend take his rocker arms loose for the winter.He didn't take the spark plugs out and was turning the engine to get pressure off of each rocker and when he got one side finished the starter wouldn't turn the engine over it locked.So he took the spark plugs out of the side that was finished and not the side he had left to do.And he proceeded to take the rest of the rockers loose.I asked him if that would hurt anything and he said no it should be fine.So my question to everyone is will that not hurt anything.It is a BBC and is around 15.1.Thanks
