Recently purchased a 2002 RSX with higher miles but the price was right. It has around 160,000 thousand miles on it. The engine runs fine just that valves were a little noisy, after adjusting them twice I notice no difference in sound. Could it be that they are that worn that even with adjustment they are still loud?

when you did the adjustment how off were they?

Trying putting a thicker oil like 10w40

I dont know how much they were off because i undid the jam nut before checking them

Pull the valve cover again and inspect the cam lobes, check for cam galling. I'm betting the intake cam lobes are pitted out. Also make sure you are running 5w-30 and not 5w-20 oil.

Why 5w30? the oil cap says 5w20

Honda changed the oil weight requirements on all the newer K-series engines from 5w-20 to 5w-30. 5w-20 is mostly for fuel economy purposes, it does little to actually help protect engine parts. People who have ran 5w-30 have had less issues with the cam galling problem because it's a little bit thicker oil.

tai....

i have the same problem with my ep3 my valves are really loud , so im getting one of my honda techs to do the adjustment for me and see if it changes..also i will be running 5w30 once i get an oil change
