Ok, I need advice here. I have a stock 91 CRX Si with 165,000 miles on the engine. I did the valves two days ago. I set them just a bit closer than spec, I went .006 intake, and .008 exhaust. Anyway...

I did the valve job, ran it, tracked down 8 of the valves that had to be re-adjusted, ran it again, everything was whisper quiet...BUT...

My car has had this VERY noticable ticking sound ever since I can remember. I am absolutely sure it's not valve noise now. I've heard the following ideas... noisy fuel injector(s), sticking valve guide(s), predetonation...

I know its not predetonation, simply becuz I've been running 89 octane fuel for the past year, it's bone stock, and the timing is set right to spec. I'm hoping it's not a sticking valve guide, cuz I can't afford to do valve guides. Any ideas?? The noise is always there, but much more apparent after the engine is hot, and it sounds like just one cylinder is making the noise. It changes speed with the rpm, and doesn't seem to care if the engine is under load or not. Ideas?? thanks guys
