    Noisy ass valve train... is this normal?

    So i just bought my used 07 WRX with a little over 50k on the clock...

    i've noticed that the vlave train is extremely noisy, there's ticking, etc... almost sounds like a small tractor lol... but not as loud... i'm sure it's not knock, there's no power loss, car runs strong and idles steady...

    so i guess my question is, is this normal?

    Our horizontally opposed motors are notorious for having loud valve trains. some ticking is normal. There are plenty of threads on the forum with people changing oils and having some success with lowering the tick.

    At idle your car is going to make all kinds of noise. I discover a new noise with my 09 almost once a week lol...
    Your vehicle is an extension of your skill as a driver, not a substitute for it.

    My 06 has noisy valves too. Typical for a lot of vehicles nowadays, add winter weather and it's louder.

    Word... i'm not so worried now... lol, and i've noticed it's louder at idle, doesn't do it so much under load.

    I'll try changing the oil soon and see if that helps. any suggestions on brand or weight?

    The fuel injectors on pretty much all Subarus in general are louder than some other cars also..at least from my experience.... Perhaps your hearing the injectors pulsing...

    Yeah, injectors too, just like my 4runner, although the Sub is louder.
