    Exclamation Newbie with a question!

    I just bought a 2002 subaru wrx automatic (good price so i had no choice) with 136k stock runs great! but when i first start the car in the morning i hear a little knocking sound, after about 10-15 minutes of driving this sound eventually lowers to the point that i can barely hear it but it is still present! It also has a small transmission leak, about how much would cost me to fix this leak? The car has a lot of miles and i would like to not spend too much on it. But I am thinking it would be a good idea to take it in for a check up and if there are problems with the car i will just fix the most important ones.

    Sounds like piston slap in the morning. If so, normal and not much to do. Make sure the timing belt was done at 105K. Welcome.

    WRX/STI Motor/piston slap/Valve springs

    my buddy seems to know alot about WRX/STI motors im learning alot very fast. i have that same sounds. He said we could drop the motor and torque the valve springs down to stock torque and it will help but he also laughed and said WRX/STI motors have the worlds worst idle.. haha.. i said ok .. but im not sure if you do have to drop the motor but i would think so because you cant get into the valves due to pistons on the side VS. the top.

    Yea, that sounds pretty normal to me. Hard to tell 100% but from the video it sounds normal. Probably just not used to the boxer motor sound. That's how I was when I first got mine

    Generally no it won't really get much worse.
