Is my engines noise something to worry about? I know old hondas make tapping sounds because of the mechanical lifters, is this too much noise? The car is kind of a shitbox, worth maybe 500 € so is it worth to do anything about it? I already adjusted the valves but it didn't do anything to the sound but made the performance a bit better. The clearances were actually a bit tight so i loosened them up. So even with tight clearances it was making this sound. Listening on the valvecover with a screwdriver I can hear little bit of tapping but listening the fuel injectors and fuel rail the sound is a lot louder in the same pace. I ran a bottle of injector cleaner but it didn't do anything. There's no tapping sound on cold mornings for a few minutes after starting, I think because then the oil is thicker, but when it warms up and the oil thins out the noise appears. I also changed the oil for a thicker one but it didn't really help.
Anyways, the car runs and works good, only issue is the noise being annoying.
