I appreciate it more and more as time goes by
Yes.....cooling system can only be assured for no more than 80-100k miles. Many do the overhail well before that. Expansion tank, tstat failure, WP failure and temp sensor o-ring are all places of concern.
All vanos units have inferior o-rings installed on vanos pistons, when they are built and can become brittle in as little as 20k miles. Replacing these is a must and is a very easy diy. If the zhp does not have standard vanos rattle, then it most likely will not develpoe one.
So you only have to replace vanos if it develops a rattle or every 20k regardless? Sorry for the noob questions...
Regarding the rattle, yes. You only need to do the seals once.

Found an 05, 55k, premium, cold, & nav here in L.A. Unfortunately it is steptronic not stick but I got a good deal.
Took it out to the Malibu canyons Sunday and had a blast! Will post a pic later... Thanks guys!
I wouldn't worry about the autotragic, manual swaps are pretty straightforward. :)

Mostly just a parts collection. Beyond that it is fairly plug and play.
