I have a 1972 Bay with a 4 cylinder VW Santana engine and a 3 rib VW 1600 Bay gearbox. I have had the engine timing gears off to change leaking crankshaft and camshaft oil seals, and have just put it back together and used the existing timing marks to time up the engine. During the investigation (to figure out which of the many home applied timing marks were correct) I noticed that there is no timing aperture on the bellhousing as there would have been for the Santana (as its now a Bay gearbox and bellhousing), so I'm pondering how to set up the ignition timing properly. I've done it statically but with no timing marks I don't have a reference. While typing this I started to think - I have a TDC marker on a pulley - I could put a reference mark on the crankcase and add a timing mark on the pulley at 18deg BTDC and use that as a dynamic reference. Does that make sense?
Rockers rocking on No1. Probe (pencil/ stick) in NO1 cylinder and feel for TDC . Then marker or a hacksaw cut filled with paint on pulley.
