I've recently been doing some work on a 1998 Honda CR-V, with a b-series engine. This vehicle had a burned exhaust valve, which I've replaced.
After doing a rebuild and reinstalling everything, I'm hearing a lot of clatter from the engine; I've posted a recording of the sound here: https://www.youtube.com/watch?v=64znW-20Dxo
I know these engines have a reputation for being noisy, but I'm not sure if this sound is just normal valve clatter, or something else--in particular, I want to make sure that I don't have piston/valve contact. I've set the timing, and adjusted the valve lash when I put everything back together. Compression test shows 184, 174, 174, 179 dry.
One thing I noticed is that someone marked the cam gears with a paint pen, a few degrees from the "normal" etched TDC marks. When I put the timing belt on and set the timing, I used the etched marks. Is it possible for the cam gears to be out of alignment? I left them attached to the cams the entire time.
Any suggestions or opinions?
EDIT: I should also add: The sound doesn't appear to be isolated to a single cylinder; pulling the plug wires one at a time doesn't change anything.
EDIT 2: I can pull the plugs and rotate the crank manually through multiple revolutions--there is a point in the rotation where there is a very slight amount of resistance, which I assume is just due to compression. I don't know what piston to valve contact would feel like, would I know it right away, rotating the crank by hand?
