    Nosiy engine?

    well i got my cb7 a week ago and ive been tuning it and fixing crap since.. but the one thing i can't figure out is, why dose it sound like (if there were lifters) the lifters are clattering? i was looking at the correct timing diy and i was considering it but wanted to check first.. indeed im a n00b to this 4cyl and yeah any input would be great, thanks in advance

    also, when the engine is running at normal temp, and i put it in reverse i hear a thud, i was thinking its the motor mounts but it only comes from the passenger side?

    Without a sound clip, I have to assume your engine sounds like the rest of our engines. Welcome to the world of Honda. It took me a while to get used to the overhead cam and injector noise. You're actually hearing some normal valve noise, and the injectors make their own little noise when they open and close. Post a video clip if you're really sweating about it so we can hear it.


    How does the thug sound? Metallic? Solid? Hollow? A better description will help narrow it down, but I'd assume a bad mount. Have a friend you trust sit in the car and shift it into and out of reverse while you look for the thud.

      Our engines are known for valvetrain noise. Our injectors are noisy as well.

      Adjust your valves, and try a different oil. Unless something is significantly worn or damaged, one or both of those things will fix it.

      As for the shifting thunk... the transmission is on the passenger side, which is why you hear it from there. I would definitely inspect your motor mounts. If your car is automatic, it may be the transmission. If it is manual, there really isn't anything inside that would do that, so the mounts are pretty much all that would create such a sound.

        Yes, I need a valve adjustment as well. Tap isn't uncommon at all. It's depressing.

        life is good.

              Low brake fluid, or faulty park brake switch.

              Blown fuse or faulty brake pedal switch.

              A "Finished" project car is never finished until its been sold.

              If at first you don't succeed, Try again. Don't give up too easily, persistance pays off in the end.

                  The parking brake cable could also need adjustment, though the reasons given above are more likely.
