The spun bearing thread has really got me worried. 
I've owned my car for a few months now and have noticed the same problem from second one -- a tick, tack sound coming from the motor at idle and at low rpms (below 1500).
It happens at low RPM's and goes away under load or when reving the motor. It comes back afterwards though at idle or when the revs drop again.
I've listened and have had a hard time localizing the sound. I don't know whether I'm just covering it up by reving it or if it really just goes away. Occasionally it's noticable in the cabin, almost like something is tapping on the firewall. It will quickly subside though.
I have noticed this sound from second one and almost walked on the car because of it. The fact that it went away under load led me to believe that it wasn't rod knock or a larger failure.
I did an oil change the day after I bought the car and saw NOTHING in the oil -- not even clumpy dirt particles that I've often seen with other cars in the past. I've since driven the car 2k miles with no performance problems what so ever.
Is this the boost solenoid, a spun bearing, or just the standard lifter tick? Keep in mind that I had a DSM before and am used to light tapping from the valvetrain. The louder tack sound is what has me worried.
I'd planned on putting a half quart of atf in with my next oil change to see if this clears the problems. It's worked wonders on DSM's in the past and I see others doing the same here. A question on that -- do you guys put that in, run it through and drain it or do you just leave the atf in with the oil for the duration of the cycle?
Thanks in advance for any information you can provide.
