Are you doing this without a manual? There should be an indicator on the timing chain cover and degree marks on the crank pulley. That will tell you where crank TDC is. I hope the pointer isn't adjustable as on the OM603. Without knowing how to align the cam sprocket to a reference or knowing the specs of the cam, it'll be difficult to check cam timing. The rule of thumb will be to check that the intake valve just closed so the #1 intake lobe point should be about 90-degrees past the valve stem and the #1 exhaust lobe point should be about 270-degrees from the valve stem. Distributor timing is less of a problem since you can check it with a timing light while cranking.

These are generic suggestions. There might be nuances of the M127(?) that I'm not familiar with.
