What are the cylinder numbers?
Cylinder identification is a simple, yet very important detail to know. For example, if you are having compression problems a mechanic might say, "You have low compression in cylinder #3." Ok, which one is that? There's four of them!
Even with a Bentley manual, finding this info is like a needle in a haystack. Here's a simple diagram for this much important info:
This applies to all wasserboxer (waterboxer or WBX) Vanagon engines. Please note the reference to the front of the vehicle and not the front of the engine. Keep things simple, front is front.
Printing this off and storing it in an easy-access spot is a good idea. I know some people that even tape it in the engine bay, like on top of the air filter box. I DO NOT recommend this for a number of reasons. If you go this route, just make sure you keep it away from any heat source! Keeping it in the glovebox seems like a good, safe place to me.
Another item that's closely related to the cylinder identification is your distributor. Here's a diagram for that:
