Hi some of them have a belt but yours being the M43 engine is a chain, the only thing to listen for with them is chain slap or an rattling around the chain area, a bit of research on the M43 engine also shows that the chain should be changed after 100000 miles as they become weak, Just joined here and found this unsolved i know its a bit late but hope the extra info helps

Remove the cam cover, remove the spark plugs, turn the engine to number 1 TDC, put a pencil in spark plug hole number one and twist the crank back and forth and make doubly sure you are at TDC. Now loosen the four bolts at the front of each cam sprocket, check TDC again with the pencil and rocking the crank, now take the pencil and lay it across the flats at the back of each cam. Twist the cams very carefully so that the pencil sits flat on each cam square. Snug up the sprocket bolts and use the pencil to check TDC again! Now check the cams again. Repeat the procedure until you have the cams flat and the engine at TDC.

Testimonial: "worked perfect"
SOURCE: 1980 volkswagen timing marks
With the #1 Piston at TDC there is a mark that you can see through the access hole on the transmission. The cam lobes should both be pointing up on #1 Cylinder. The slot on the right or back side of the cam should be level with the top of the valve cover gasket mating surface on the head. There is a tool to make sure that this is in place, but it is not necessary. There is also a mark for the injection pump that should be lined up with the gasket mating surface. There is also a tool that fits this (I use an 11mm craftsman 1/4 inch drive socket in the holes)
I bought one of my VW pickups cheap because a repair shop didn't line it up correctly and the engine would not run properly.
The directions should be pretty good in the haynes manual.
