    Knocking noise coming from the engine

    Hi All,

    Recently I've noticed a knocking noise coming from the engine, on the drivers side. I had someone take a look at it, and they told me that either my spark plugs are miss firing, or I need to adjust my lifters. Has anyone experienced something similar? Is this common?

    I have a 2002 WRX, no modifications, and I do all my regular oil changes and tune ups.

    Thanks,
    -Marek

    Who told you that you need to adjust your lifters? Whoever it was, I wouldn't take their advice.

    How many miles are on the car?
    How many miles since you last changed the spark plugs?
    Did the problem come on gradually or appear all at once?

    Miles: 105K
    Spark Plugs were replaced when I did my timing belt. about 2 years ago. About 30K miles.

    Not sure if it was gradual.

    Local mechanic at a shop told me that. It didn't make much sense to me, so I excused myself and went home.

    Let me know if you need any more info.

    Thanks,
