I read an evaluation of a 2001 SL500 on mercedesheritage.com and was surprised to find the following:

“... we’re aware of failing crankshaft pulleys on many of the 2000 and later V-6 and V-8 cars. If left unchecked the wobbling pulley will slowly machine a nice groove in the front engine cover eventually requiring its replacement, a very expensive repair... “

I had never heard about this before. Is this a common problem on our cars?

I think the author is not talking about the balancer. Here is the rest of the article:

“…We check all the pulleys and tensioners on these cars and after checking our SL, requested MBZ to replace most of these items. So there are now a few more entries in this cars warranty data bank…”
