If you are watching this you've probably already seen FCP Euro's video but I would recommending following that as a primary guide:
Part 1:    • BMW N20/N26 Timing Chain Replacement ...  

Part 2:    • BMW N20/N26 Timing Chain Installation...  

This is meant to act as more of a guide on how to do it at home without a lift or special tools.
See bimmerpost thread: https://f30.bimmerpost.com/forums/sho...

You can find the tools and the shopping list for tools here: https://blog.fcpeuro.com/howtorepla...

For xDrive owners please see:    • 2014 BMW F31 N20 Timing Chain Replace...
