Since I have two cars with the M119 engine, one with 130,000 miles and the other with 150,000 miles, I’m gathering information on changing the timing chain. I’m fairly mechanically inclined, so I’m assessing whether I should attempt the job myself. Opinions regarding the timing chain replacement job on a M119 would greatly be appreciated.

The scope of the timing chain replacement I anticipating will consist of just the
Timing Chain
Chain Tensioner
Upper Guide Rails
** No lower guild rails or rail pins** I know this is beyound my skill level

I have the Alldadydiy procedure which outlines the steps involved in the chain R/R for the M119.

Since I will be performing the job solo, without any help, I want to make sure I have the proper tools to minimize the task.

As I was searching for tools for the job I noticed the following tools and was wondering if anyone has had good experience or are there other alternative.

double chain crimping tools
camshaft chain guide tool (Which one for M119 V8)

I currently have the cam shaft locking pins to lock cylinder 1 at TDC when removing the chain tensinoer.

Depending on your comments, if I decide to tackle the job myself, I'll take pictures and share my experience with others on the fourm.

Thanks!
