I've been tearing down engines on camera for 2 and a half years! Search my channel to see what I've torn down. Here's a few recents:
Mini Cooper/PSA N14    • JUNK Mini Cooper S (BMW/Peugeot) N14 ...  
Ford 1.0 Ecoboost 3cyl    • JUNK Ford Ecosport 1.0L 3Cylinder Ec...  
Infiniti/Nissan VR30DDTT    • 60K Miles on 1 Oil Change!?! Infiniti...  
Dodge Ram 8.0 V10    • 8 LITERS OF DESTRUCTION! Dodge Ram V1...  

Its been over 2 years since I've torn down an N55 on this channel! The N55 comes in a LOT of BMW cars and SUV's including the 135i, 235i, 335i, 435i, 535i, X5, X6. Its a single turbo all aluminum inline 6 making 300hp, about the same as its predecessor. Personally, I am not a fan of these engines. I find they are extremely picky with maintenance and oil pressure but the biggest detraction to these engines is the cost. They are over double the price of their predecessor, and are in MUCH shorter supply. They do offer some advantages over the N54 like the fuel system which can be quite expensive on an N54 car.
This particular engine is from an E70 chassis X5. Its a core return I bought from another salvage yard. The last N55 parted out VERY well so I figured I'd give it a shot again. This one... well. Its not as good LOL.
Why am I doing this? I own and run a full service auto salvage business called Importapart. Part of our model involves buying core and blown up engines to tear down and salvage the good parts for resale. We do not rebuild engines, merely supply parts to those who do.

I really hope you enjoyed this teardown. As always I love all of the comments, feedback and even the criticism.

Catch you on the next one!
