13 minute(s) of a 417 minute read

Sorry guys, I have been kinda buzy (work + garage) to update the thread here - so I will fill you in:


Got a package the day befor I went to work: "New" M106 block.





Also refurbing a B9 engine at the same time.

New block ready for paint etc









B9-engine to be in position






Ready for action:





I just went for solving the oilpressure issue, here we go!









Head must go off









This one should be in the car, not outside






Some misc pics












The B9-engine owner getting ready for dismantlig






Myself was working on my own car







Deja-VU??






No gearbox










Some internals seeing daylight again







Back to basic ??







Ehh.. What??






B9 also going on...







Back to the B7 engine block







Quite a while ago







Pic of nozzles, but only 4 showing in this pic...



Pic from today, showing the last two cylinders...






Another angle







Zoooooming







What the heck??? Obviously the 2 nozzles are missing. My guess is that when I washed it, they fell out, without me noticing it...


So... What's next?


I decided to use the "new" block due to better measurements in the cylinders. So I just had to convert the M106 to "Alpina spec"









Oil return








B9 picture






Refreshed the "new" block






6 new nozzles










6 x nozzles in position






Just checking tolerances, 100%







Pistons







Alpina had (on this engine) 92.08mm cylinders, and the new block has 92.00mm, so I traced 6 used 91.97mm pistons






Ready !!







Nice with good friends and good mood!







Keep on truckin' !! Pistons on their way!






Ring end gap 100% also







All in!







New oil pump in position







Closer....













More work done:







Gearbox and block in position!







2 seals instead of one, no leaks please







Just locking the rear left shaft, to prevent it from moving.







BMW gasket







cant stop now??








Aaaaand it is on!








ARPs mounted








ready for first start-up







Finally oilpressure by just cranking the starter







1.5 bar @starter, that is 1 bar more that with the other block installed.


First start-up, no exhaust - no nothing.






not bad for first start-up



Finally!! Celebrate!!







Idle warm engine







0.8 bar idle is ok. Touching the throttle, it goes to 1.1 at once... Some more revvs, I have 3.0 bars at once.







One dirty engine...













Turbo







Right wheelarch







Dry glue, and clamps off








Left:








Holes for the Alpina spoiler







The instrument panel does all the time finds new problems, so only one thing to do:







US-refurbished






Aaaagain???







Old VS new







back in business







And it works. Got a temp sensor from George Graves:







Better...







And it works!!







Some paint....
