Thread: TDV6 crank and crank bearing failures

And incorrectly fitted oil filters on the 2.7 is terminal also all being bunched in engine seized / died category

2010 TDV6 150kms - blows blue smoke and has a loud knock… what’s the chances of it just being a big end bearing and not further damage to a conrod or crank?

And the piece of string is how long? It doesn't really matter as you have to remove and strip the engine anyway. So the strip down cost won't change. The rebuild/replace costs are another matter.

Bearing shells can be replaced from underneath yeah? Would it be worthwhile just pulling the sump off and inspecting, and if nothing else is obvious, just replacing the big end bearings and seeing how it goes?

Doesn't explain the blue smoke.

I very much doubt that a loud knock can be due to worn bearings.

Well, you can...

Almost looks like you only need to replace the bottom shells on the mains. The tops look pretty clean.
