It is not a certainty that any one engine will suffer bent rods.

I remember a thread on this forum giving a figure of 30% or so of the engines were thought to be so afflicted. Of course, if it is your engine, this jumps to 100%.

As others have said, don't obsess, just do the regular maintenance, drive it and enjoy it.

I think my OM603 with 258,000 miles has the equally problematic #14 head. It will probably die of rust, or someone will crash into it, before the engine dies...

Best Regards,
