The crank sensor wheel, timing chain, etc. The gap can be seen on the left side. The crankshaft Woodruff key slot probably points straight up at #1 TDC, but remember that this is an *offset* crank so a much closer look would be needed to determine if it points straight up, or a couple of degrees over at the piston centerline, or what. Similarly with where the flat spot on the wheel would be. As long as the ECM knows what's going on...
The sensor plate on the end of the intake camshaft. The three little pins pass close to the pickup [pink arrow] to trigger it.
