About

Welcome to my channel, I Do Cars. Its an answer to the awkward question "So what do you do?". On my channel you'll find videos of the dumb and overzealous car projects I take on personally. You'll also find videos of getting cars running that are either wrecked, or have been sitting for a long time. There will be some how-to repair videos as well because showing people how to fix their vehicle themselves is what I love to do. Of course, you'll find engine teardown videos. Lots, and lots of engine teardown videos. One a week, at least. I own and run an auto salvage operation and part of our model is tearing down bad or core engines and selling the parts. Taking these engines apart is just another day in the office, so I'm happy to bring you along!

Check out our website at www.Importapart.com or email us at [email protected] for parts and part inquiries. 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 https://youtu.be/Yfolxiin_Wo Ford 1.0 Ecoboost 3cyl https://youtu.be/0yx1-50iqnA Infiniti/Nissan VR30DDTT https://youtu.be/HB-wzyIq_pQ Dodge Ram 8.0 V10 https://youtu.be/Ot-GbhaeaDw 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! -Eric Very Helpful links to N55 Owners Link to Vanos bolt recall: https://static.nhtsa.gov/odi/rcl/2014/RCRIT-14V176-8438.pdf Link for pre-oiling TSB after breaching oiling system for service for all late model BMW engines.
