3.0 TDV6 broken crankshaft / engine rebuild

[Fabsky]

Hello everyone. In my Discovery 4 3.0 TDV6 it refused to obey and more precisely the crankshaft broke. I decided to fix it myself. I am addressing all those who have done it before, that is, what is also worth paying attention to / refreshing beyond the main fault so that the engine will be used as long as possible.
Can anyone recommend proven sources where it is best to buy engine parts? I will also be grateful if someone has a shop manual for the engine with technical data.
I tried to search this extensive forum but couldn't find the information I was looking for. If I missed something, I am sorry.

Cheers
Fabian

Before considering this you should know what you’re heading into. LR Time videos of their repair gives you a good start: Is this the end? Complete engine failure - Land Rover Discovery 3 / LR3 - Episode 1 - YouTube

The manual available on this website is really good mate, good luck with the build. Take heaps of photos and post them up. Plenty of people will be interested in your journey.
As for parts if I had to do it I would probably aim to buy genuine where possible. Depending on price

Good luck with the rebuild, way above my pay grade but am interested in photos as well. I believe my indie goes to BMI – Welcome to BMI's online store if that helps.

The manual doesn’t have bottom end info unfortunately (well mine doesn’t) but I did come across a Peugeot manual for the bottom end at one point which covers it off. I’ll see if I can find it and flick it through.

If you become a patreon of LR Time you can access detailed data on the gear they used / built / bought and allows you to ask questions. He has the rebuild and parts books for everything. They did rebuild a 2.7 though although he does mention relevant component differences to the 3.0 quite a lot. The initial bearing set he bought was for a 3.0 not 2.7.

Unless there was valve damage the top ends last a long time although freshening up the lifters and chain gear is worthwhile.

Thanks a lot to everyone for the answer. In general, I have already taken big steps and so far everything is going well.

simonmelb - I've seen their videos, they're very helpful. By the way, I saw a few other brave people who were my inspiration to take up this challenge.
josh.huber - already bought the manual from Dave and I'm starting to browse. I hope I will find all the necessary information when assembling the engine.
rambada - thank you for the information, I will have a look there without a doubt.
DiscoJeffster - This is not good news. I hope the manual I just bought will include this chapter. If by some miracle you found the manual you mentioned I would be very grateful.

Copying a few relevant and interesting short videos to this resource as a Plan B. Same process I think DiscoJeffster had done on his 3.0.

I’m loving the 1minute format! How are the thighs feeling after three days of doing squats?

Magnificent effort.

Were you were able to get that exhaust cross over out entirely via access through the wheel arches?
