I bought a 2000 WS6 earlier this year. After changing the oil I noticed a slight ticking noise coming from the motor. This is the first ls1 I have ever owned and was wondering if this is normal. It only does it at idle and sounds like a lifter to me. Any advice would be appreciated.

 

I have a 2002 WS6 it has always had the ticking noise until it's fully warmed up. If I rev it a bit it goes away for about 20 sec then comes back only until warmed up then it's completely gone. I believe it's the O-ring problem or the lifters are fast bleed down.
