NA-not to be a geek, but doesn't it mean there is something wrong with the timing chain if the ticking sound starts? I mean I don't expect the thing to just snap, but it means its starting to "slack" right? or am i being way too paranoid?

Way too paranoid. My car rattled when I bought it at 27k miles. The chain might be slacking a little, but it would need to slack a considerable amount to cause concern, and if it did it would be due to severe oil pressure loss. The top and upper guides are delete items simply because they were deemed useless and caused the noise that worried a lot of owners. If you're really worried, install a high quality oil pressure gauge. That will indicate any possible issues with the motor and save you when/if something occurs.
My 180k mile motor lost a sending unit one night under a violent run and I shot nearly all four quarts in the pan out on to the road. With zero oil pressure I was able to shut it off, plug the hole up, and drive it a half mile with no oil, it made a little noise but after a flush and fresh oil change I continued to beat on it until I parted the car.

Yeah man don't sweat your motor. I'm paranoid too. Since my car broke 100k about 3 years ago, I've been wanting to drop in a new motor. Now I'm at 190k and it still runs strong with no leaks or quirks. I'm just worried about it blowing and leaving me stranded on the I5 at midnight....

Luckily I've got a guy lined up that's going to sell my his KA with 70k on it for $400 cause he's going SR. So i'm looking just to drop it in cause you can't beat it for 400 bucks. Besides I'm planning on going turbo and I want to have an extra KA laying around to build up for the boost, eventually.

Oh and just to let you know, I use Lucas oil stabilizer at EVERY oil change and my chain clanking is gone. I haven't removed any of the guides. But if I ever change the oil without the Lucas the clanking comes back. Just a tip.

Good luck....glad to see another guy not jumping on the SR bandwagon.
