I am starting to see a lot of MBs with the M272 engine with timing chain problems. These usually have 150 to 200K miles on them. Some have skipped timing, some report as running very poorly. Others turn over but won't start. Some are almost there, run and drive, but horrible timing chain noise on start up. (I notice these because I am always looking at inexpensive MBs on FB marketplace to add to my collection, or to fix and sell.)(I also have two, an E350 and an R350)
As I understand it, I could fix mine and some of the others by redoing the timing chain without pulling the heads. But, if I am to do chain guides (which I think are usually trashed too), I would have to pull the heads. At this point, I am wondering is it worth it?
I am thinking about just pulling engines (maybe parting them out) and replacing with a good used M272 engine from a Copart, IAAI purchase, LKQ or car-part.com.
Your experience/opinion gratefully received.
PS. I am posting in the W211 forum because I am guessing that the E350 is by far the most popular MB with a M272. But, If I am wrong, it is the C Class, I am always happy to be corrected.
