G'Day guys, I have 2 questions to ask,
1) Can someone please advise me on how to change the air con tensioner pulley on the
LS1? I can't come up from the bottom cause the cross member is in the way and I have massive hands so it's awkward to get to it from the top,so any ideas would be great.

2) The lifters are pretty bad and even up to runnin temp they clatter away all the time,am I doing any major damage to the engine by not getting them fixed? I'm tapped for cash for the next 2-3 months so it will be awhile before I can get them fixed. I have tried mobil 10w40 and in there now is castrol edge 10w60 plus I've used nulon lifter free on the last 2 changes.Basically I think they are ****ed.
