Valve Stem Seals Part Number for 6.9 Engine
« on: 31 May 2021, 01:19 PM »
Hello,

Two quick questions to those that have rebuilt the head of their 6.9 engines:

1. Are the Valve Stem seals unique to the 6.9s M100 engine or are they generic to different MB V8 engines? 
2. Would anybody have the part number for the Valve Stem seals of the 6.9 engine?

As always,  thank you for the assistance.

Best regards,
Angel

is this definitely the right number?
coincidentally I was speaking to my old German mechanic about this very thing a few weeks ago and he noted they were unique to the 6.9 (im pretty sure he said 6.9 and not just the v8s of that time)
but the number you note is a 115? I dont know the number but interested to know now.
6.9 79 #6436
6.9 79 #6290
6.9 79 #6181
6.9 78 #4764
6.9 77 #3096
6.9 76 #1741
6.9 76 #0902
6.9 75 #0018

Dear Daniel,

Once again, thank you very much for the assistance:  I greatly appreciate it!!

Based on the part number, these Valve Stem seals appear to serve on several MB models.
Is my understanding correct?

A lot of people and shops like to "upsell" the 6.9 by saying certain parts are unique to the 6.9 engine or chassis.  Doing so pads their pockets and egos more.  It's a deplorable way to conduct business, but it happens all of the time.  The "115" part number is correct.
