I own a W211 with an early 3.5L M272 engine (109,000 km) so this is interesting. You are highly skilled-watching you work is a joy! Disappointing to see disintegration of the plastic guides. Is it true that not every low serial number M272 will suffer from abnormal balance shaft drive cog wear? You didn’t choose to replace the original cog as a precaution? Will watch the final episode tomorrow, I’ve subscribed of course :-)
I have a M272 coming out of a 2006 R350. My son totaled the car so now I have a car I’m parting out. I am going to to rebuild the engine it’s at 180k. Great video do you have a rebuild manual that has torque specs and which bolts need to be reused, etc?
@@internalcombustion1416 Thank you very much for all your replies. You have inspired me to do an overhaul on my engine which has 180000 miles on it so it will serve me well into the future.
Love your videos. Impressive!
Meticulous attention to detail. Impressive.
I love the background music
Great work.
you are doing a great job. Please try it till the end. I'm looking forward to the next video.
What is the bolt torque specs of crankshaft main bearing?
Is there any chance you could post a list with the torque specs? That would be extremely helpful!

I did replace both the cranksaft cog and the balancer shaft. All timing parts are new on the engine!
I am not sure about which M272 did suffer from the balance shaft issue
@@internalcombustion1416 Engine serial numbers below 2729..30 468993 have the balance shaft issue.

Looks like you were comfortable using the old water pump?
I actually did replace the water pump in the video anyway, the old one wasn't that good!

Reused the old roller tappers? Just inspected?
I inspected and replaced 10 of them 👍
What was the year and the mileage of the car? Thanks.
