What should the timing marks be on a camshaft?
After you have installed your crankshaft and camshaftand connected the two with your timing set, take a moment to make sure you have your cam installed “straight up,” which means the tick marks on the timing gears point toward each other. At this point, the camshaft should be installed as your cam manufacturer intended.
Neglecting to replace these parts can result in serious engine damage (valves hitting the pistons). Mercedes-Benz updated the M102 engine to receive a double row timing chain in 1988.
Do you need degree wheel for Camshaft Timing?
Before you start any of this you will need to have a degree wheel to time your motor: Finding piston TDC Timingyour camshaft involves measuring total lobe lift, the lobe centerlines for both the intake and exhaust lobes, camshaft duration at 0.050-inch lift, and lobe separation.
How do you time the intake cam at TDC?
If you are timing the engine or valve train and need more precision there is a small hole in the back of the cam sprocket. To time the cams at TDC install a small Allen key into the hole in the back of the sprocket and it will lie flat on the head by the cam journals (red arrow) when at TDC. The same procedure applies to the intake cam.
In 1984 engine got new light connecting rods and crankshaft as well as hydraulic tappets/lifters and the new style oil filter. The 2.0 L M102 from the beginning had the single-strand timing chain that was very unreliable, in 1987 this chain was replaced by a more durable double-row chain.

How do you change the timing chain on a 22R?
Remove the one horizontal mounting bolt up front and the two vertical mounting bolts in back and use a floor jack to lower the front differential assembly. Alternately, you can remove the motor mount bolts (2 per side) then use a cherry picker crane to raise the engine a few inches for clearance to drop the oil pan, if needed.
