I have a 94 Honda accord Ex (F22B1). When I bought it a few days ago the previous owner mentioned a few of the issues that he could remember. Since I've only ever owned Honda's and have worked on them for some time I figured there wasn't a problem I couldn't fix. This one has me a little perplexed. I started it up and noticed that valve ?tapets? (sorry don't know what they are really called) were all loose and making noise. That night after the engine had a good chance to cool down I took the valve cover off and used my old trick of a 1/4 turn loosen on all the valves from full tightness. (Side note: This wasn't a blind un-thought out process. if you want to know more we can chat about it)
Put it all back together and it went from a full on clickity clakity motor to much quieter engine. However one of the valves is still making noise. I figured that because I did it sorta late and in a hurry that I didn't do as good of a job as I should have. So after driving it 120 miles the past few days and a much needed oil change I figured it was a good enough time to let the valves settle to their new clearance and decided to tighten them up again today but this time take more time doing it. Get it back together and one of them is still making noise. I'm fairly certain it is the #1 cyclinder's valves but I am still kinda guessing on that. Anywho I've just never had that happen to me before where it was still making noise after adjusting all of the valves. Any suggestions?
Last question: How do I know it's not the rod bearings? I used to think it was speed between clicking noises, but when I put my head in different areas of the engine bay it sounds like it's coming from the front of the engine and gets louder when I put my head closer to the exhaust manifold instead of next to the valve cover.
