Help
So I was helping my son changing a head gasket it's a 2001 Honda Civic 1.7 D17A2 everything went good until we turn the engine on to check it and I heard some weird noise on the valves I open the oil cap and saw one of the valves was not moving like the other ones. what do I have to do now? Also I took the head to a shop to get it resurface and they installed new valve seals any advice is greatly appreciated it

If you think a good mechanic is expensive, try hiring a bad one
Re: Help
What kind of car are you working on?
Does it have 4 wheels? (all cars with 4 wheels are the same, you know!)
Year, model, trim level, engine size, type, and code
The machine shop probably took the entire head apart. Did you reassemble the entire head correctly before installation, or are you trusting someone there did it correctly?
Did you adjust the valve lash to correct specs?
Remove valve cover and adjust valves if you need to.
While you are in the process of adjusting the valves, you will be rotating the crankshaft. WATCH ALL of the intake valves as you spin the engine by hand. Are there any other valves that act the same as the one you could see through the oil cap hole?

Thread moved.
With VTEC the cam has dual intake lobe profiles: one profile has very low valve lift and the other has higher lift. Could this be what you noticed?
