Hi,

My name is Duong. I have a 99 CLK430. My lifter has noises in the morning and the dealer advised me to change them out (24). Is it hard to replace them? What's a good procedure to do so? Is it necessary to change the timing chain at the same time? While I'm there, is there anything else that make sense to replace at the time? Thanks for all the advices.

Duong
