Carl,

I suspect that you jump tooth, either when you moved the timing gear to get access to the guides, or when the guides broke.

After you have it at 45 left side pined, then remove the right side gear move& pin the cams.

Try, see if that works. You can always put it back where it was....

I think you only replaced the tensioner/ large guide and the two upper guides?

You have NOT replaced the two bottom left. Am I right?

What if they are broken??? Wouldn't that effect the pining?

Also look at the vibration damper make sure that is not broken.

They are known to divorce/ separate.

Regards,
aam.

aam,
I replaced the guides shown and explained in photo below. However I'll try moving the right side cams and pin them, then I'll rotate the crank to 45 TDC and see if I can then pin all the cams.
thanks

aam thank you. I read the post you have referred to, as I had read this before, but by reading it again and again after a few days of rest from searching info, it now makes sense, I have a 6 degree timing chain stretch, way to much for me. So now its obvious, I am going to replace the chain. I have the M119.96 engine, another thing I read as the tensioner guide is not as curved as the M119.97/98 engine, however my old tensioner rail had 2 deep groves so I did replace it and I do recommend anyone else to do the same, as it's not that more difficult that the others. I'm real lucky my m119 engine did not seized as I was driving it that way until 2 weeks ago. Now I need to search more as to how to roll in a new timing chain and what special tools I need. Has anyone done this recently?. As I'm learning........

Thanks for the picture, I wanted to see the condition of them.

In order to replace/hold the timing chain.
You will need.

Chain retainers # 602 589 01 40 00
And # 604 589 00 40 00
Those tools are also used in Engines OM601 to 606, 119.960.
A double chain riveting tool.

Look to their forum as you know there are tricks.....;)

The reason I brought up, my other old post Engine Ticking.
Yes,
It was for the posts that I mentioned for you to see....

I was looking to find something to help you... I forgot where. :(
Anyways I did see a post that mentioned.
If the check valve #48 in the oil filter housing
leaks.

That may cause the GUIDES to BREAK.
MB, sells this check valve kit.

In my pictures you can see the check valve, is the one that I suspected that it started my ticking problem....
I didn't have to replace it.
Just cleaned it.

Regards,
aam.

Thank again aam. I'll remove the oil filter housing, replace the O ring and look at that check valve.
