I have a 2005 BMW 325i (N52B25) with a real bad oil burning problem. So I decided to rebuild the engine. The following video series is everything you need to remove the n52 engine and put it back in again. I hope this can help educate any of you looking to do the same engine removal / swap (even on a n54, n55 or e91, e92 car). I had to piece together a lot of information and have many people to thank (including in this forum) so I hope the video series can help many of you to keep your cars running strong!

Swap over all the parts that you need from your old engine (wiring harness, all accessories, fuel rail, vanos, coolant pipes, spark plugs, exhaust headers etc). Install new gaskets on everything and get it ready to put back in the car.

Zdecydowanie do odbudowy n52 zalecam pierścienie olejowe konstrukcji jednoczęściowej. Ja zastosowałem takie i nie zauważyłem po dotarciu żadnych ubytków

Fantastic video!

Did you ever figure out where the straight rubber molding (at 20:22 in the first video) belongs?

I've changed my radiator and ended up with this same piece as an extra part.

Very curios where it fits, especially since my radiator has now failed 3 times. Has me wondering of this piece performs some important damping or insulation function?

Thx!
