do a compression test to be sure...but more than likely, your valves are bent..but could be just one or two...good luck to you.

This is the most desperate topic title I have ever seen on HT. lol

You may have bent valves. Like the previous poster said, Compression test that thing. If your compression test says unusually low compression in one cylinder, pull those valves and compare them with the Y7 valves.

I am not sure if all the D series valves are the same, or if the vtec and non vtec valves are different. Some measurements with a good micrometer will tell you if the valves are the same though.
