in todays video we switch. theflex plate over from the old motor onto the new on and we also do the n54 rear and front main seal diy. these seals are special because you need to inject a special sealant as well as use special loctite primer with a special tool. this process is made very easy using the tool kit made to remove and replace bmw seals. in the next video we will be dropping the engine in the e93 body and bolting. itback up to the transmission.
