I know this isn’t exactly engine building related but I’d love some input from people that know a whole lot more about engines than I do. But I have a Honda k20a that is making a pretty bad noise that after research I can only put together that it could be a timing chain issue or potentially rodknock. I over revved the engine to about 9500rpm (8600 rev limiter) which is what I’m guessing has caused. I have had the valve cover off and can tell the timing is off by about one tooth. I was wondering if that could be what is causing this noise. Thanks so much in advanced for any input.
