2016 TDV6 Crankshaft Snapped

Jayzeee · Aug 20, 2024

Hi, I have owned a 2016 L405, TDV6 with Gen 2 engine for 4 years. Has 5 main dealer services since I have owned, the last service was carried out in May 2024 for a cam belt. Since the service, the car did not sound right. I have just covered 900 miles since cam belt replaced and the crankshaft has snapped! Car did starts but absolutely devastated. Apparently need engine rebuild?

Are there any experts on this forum who can rebuild my car?

Just had new pulleys, cam belt etc etc

Can anyone advise if they had the same problem?

And who rebuilt engine? Approx costs? THANKS

Any advise would be APPRECIATED

If the crank has snapped then it's likely you'll need a new engine block, though it does depend on where the snap is and what damage has been done

Another one bites the dust.

Same guy has a video explaining the oil problems with the TDV6. Jump to 16min in for the main info.

Are you sure the crank has snapped, and it is not in fact the camshaft pulley snapped?

I think that man is a grade A idiot, saying the shell bearings only have oil supplied once each crank revolution!

Surprised it still runs if the crank has snapped.

I’m not sure. It definitely starts and runs, but with a loud noise

I have seen a truck running with a snapped crank, I would guess it depends on where it has snapped.

The pulleys are known for going on these. I follow a firm on FB called MDRS automotive and they often post about these things detonating after cam belt changes but often it seems to be the pulleys snapping as Lynall suggests. Get someone in the know to have a look and DO NOT TRY TO START IT in the mean time, you'll do more damage.

Have a look at these guys, when our D4 detonates, it'll be going there for repair (or possibly TDV8 upgrade

) and I'll tow It there with my TDV8 L322 'n all!

Running on all cylinders? A loud noise could be many things.

Is there anyway I can attach an audio file here?
Thanks

I got my son to upload the engine noise via youtube.

Please listen to my TDV6 L405 Engine noise, link below:

THANKS

Plus 1 in not trying to start it as suggested , best to try and reduce any further damage from happening

Not sure its crank snapped but as suggested above do not run it, needs investigating, drop the oil have a look for bits, as suggested check cam pulley
