Missed a shift and over-revved the engine and leak down indicates that I have bent the intake valve on Cylinder #1. So I will need to replace it with something. Should I try to source a factory replacement valve, new or used, or an aftermarket steel valve. At this point, I am not planning on replacing all the valves, so what is my best option for replacing this one valve. Would a good straight used intake valve be acceptible, or is that being too risky? All comments welcome.

Pull all valves and inspect. if one hit a piston, more than likely it did the same in other cylinders. Likewise, inspect piston domes for evidence of contact. |
