In this lengthy video we are going to do a full detail/restoration/refresh on the M20 engine that is in my BMW e28. Since owning the car I have never looked after its M20B20 engine so I am going to do an effort to make it factory fresh. To help achieve a clean result I will be using a vapor honing/ vapor blasting/aqua blasting machine to clean up the various aluminum parts that are on this engine.

Other than cleaning some maintenance will be done aswell:
- A timing belt change
- Waterpump replacement
- Injector service/revision
- Additional air slide valve fix
- Camshaft seal replacement
- New sparkplug cables
- Various gaskets and seals
