I finally took the time to take a proper video of a bit of engine noise my car has always had. It doesnt run weird or anything it just has a bit of a knock. See what you guys think http://www.youtube.com/user/MrChattz.../0/Ct5lxUzS1xo

Collapsed lifter, plugged lifter oil channel, timing, bent valve, could be bunch of things.

Make sure you check your timing belt and tentioners, I had a car once where the timing bet slipped and it bent a valve and it made that noise. Long story short I pulled the top end apart to check the lifters thinking one was bad, found nothing wrong, put it all back together and on the first start up my tentioner went out all the way bending every valve in the motor.

It ended up being my VTC gears. I'm saving up to do the 120k kit with BDE cam gears in about a month or so. It only really makes that noise till the car is good and warmed up after a 30 minute drive or so, then its quiet as a mouse.
