M57 & Timing Chain

Heard of these having issues of course but they don't crop up like the the N47 spec issues yet the end result is of course the same.

This as stated is the first one we've seen on site and is from a 2008 vehicle ND30 spec

The story was very simple one minute driving along next minute loss of power all dash lights on and well that was it. Therefore once off the transporter the car was pushed in to the workshop. Diagnostic bought up a few issues of course so next step was to go through the basics by eye:

So we checked the usual suspects for engines cutting out (turbo's and alike)and yep all seemed well. So next step was to whip the rocker cover off and go looking.

First thing that came up for a look was the chain? We were asking why it had suddenly stopped. Could it be. Well sadly it was striaghtaway simply by lifting the chain the penny dropped. Checked looking down from te top of the head and visually on the outside we could see at least 2 valves had been distroyed.

So we were into engine transplant mode: Diesel engines in case anyone looking are damn hard to find and are expensive too. Supply/Demand sees to that. But within a week engine was supplied car back on the road.

Never thought I'd see one of these with a chain failure.

Once stripped your chain



close up the damaged link



looking down in to the head. look at the impact damage



you can see above how its been split in half with the impact like a nut being cracked with a sledgehammer
