after 30k do i need to have th valve's adjusted on my 2006 5.9?

 

The short answer, probably not. I did mine after 96k and every valve was right in the middle of tolerance. BUT these are machines and each one is different, so it wouldn't hurt to check them. If none of them need adjusting it takes about 45 minutes from hood up to hood down, as long as you are pretty handy with a wrench and feeler gauges. It's up to you, but it's probably a waste of time.
