This is one tool that every NK, 2002 and New Six owner needs!
Need to adjust your valves?  Set the dwell angle on your points?  Find TDC to stab a distributor?
We’ve resurrected the marvelous BMW tool #7008-1.  We used 4140 steel and had it hardened to RC 48/52 tool grade steel.  We then had it black oxide treated to produce a long lasting, corrosion-resistant finish. 
The Engine Turning Tool works with any dual chain BMW from the 60s to the 90s.
