Believe it or not my crate engine wasn't running right when I first installed it. I told one of the guys(master tech) at work how it was doing and he said the valves are too tight without even thinking about it. I was going to set the valves but couldn't rotate the motor and watch the valves by myself. I knew the factory sets them at one full turn so I just backed each valve off 1/2 turn and it runs great.
I told the master tech what I did and said I would go back and re-adjust them when I had some help but he said why, if it 's running good leave it alone.
I usually set valves with the motor running but this was a new motor and I spent a lot of time detailing under the hood.
