Tech question on M119 T.chain roll in
 

This question is for someone who has done a timing chain on a M119 400E.
I want to just roll in a chain,new tensioner and the guides. Question is which guides are replaced on this type of job. The one between the dual cam on each head for sure but any others?:confused:
Really do not want to remove the front of motor.Some must wear faster(or dry out)than others.
Thanks:)

you must replace the upper guides which means taking off
the front head cover. these cause big problems.

Hi George,
Thanks for the reply. Looking at my MB disc i notice there are guides on the outside of the head (2) and on the inside of the head (2 on the inside of the v-8 vee) Taking off the upper head covers i should be able to sneak out these guides? Or only the outside one's? Do the cam gears need to come off?
I ask because i cannot find these operations on my disc.
Thanks for the response
