As the owner and maintainer of a 2003 example of one of these cars (W220 bi-turbo), I can confirm that what BASCA have done here takes serious knowledge and experience. The basic design of these M275 engines is very good, using time-tested design techniques. The key to a successful and long-lasting rebuild is the attention to detail, especially when dealing with an engine with this many moving parts. You made something that is not easy, look easy. That is the mark of a pro. Well done.

Beautiful job guys , thank you😀

Fantastic video!

Job well done👍👍

Thank you.

great job

Superb job guys and congratulations

Good. Work

pallet bolts from the construction market, the E bolts are original, but they have hex bolts from a cart

Great job by Team Basca, an awesome engineering feat which looks like it was a piece of cake for you guys. Congratulations.

SUPER.

So why didn't you machine the block and heads? You basically just washed it and slapped it back together then??

How long did it take to build the new engine and install it?

Sorry to say but you missed the most important O-ring in the Cylinder Valley. The inner cover with the 16 bolts never came off in your video.

They put more effort into this video than this engine, just pressure wash it and then send the bolts?

Hey ... where can I get a V12 engine like this one?

Best oil for Mercedes with brand ?

bro you didn't show the cylinder head bolt full torque

Forget torque rods to spec just worry about bad music and stupid masks with our logo

Hey, only 48 valves to lap.

The instructions say in red - do not use abrasive sandpaper, these Papuans rub with abrasive

inserts on the block? and over tightening clearly evident when reassembling the bearing caps, even doing it up a small amount without having a torque ratchet handy.. If i were considering a rebuild somewhere i wouldn't be hiring someone that uses inserts when the block was completely stripped that could have been repaired properly, both easily and quickly. This is a cheap job not a restoration / high quality job. Sorry but i know what i'm looking at.

Why are the 2 cam shafts non identical

Sadly from 2030 on all combustion cars including classics will be banned from public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party gave order to shorten fuel supply from 2025 on by reducing all conventional fuel stations to only one state operated central gas station per city or county. Now they want to slow down all the gas station fuel pumps from 20 litre per minute to 2 litre per minute...From 2027 on in the EU certain car spares will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called "Abgasbspaßung" :-)

What a crap!
