Bus and 914 engine difference Options

[cal44]

Lads,
Not being fully versed on everything VW, I was curious if the a 2.0 Bus engine and a 2.0 914 engine are the same......Or, will a Bus 2.0 bolt right into a 914. Air cooled of course.

Also 1.7 and 1.8 while you are at it.

Thanks bunch.

Mike

Sarcastic remarks welcome, I like the humor

The Bus has a filler and dipstick that go into a funnel bolted onto the front-right corner (914 engine orientation) of the case. The Bus also doesn't have the dipstick tube on the top. On some later Bus cases, the oil filler tower is cast over solid.

Those are the primary difference in the cases, as far as I know. You can block off the hole in the case where the Bus filler and dipstick go, drill a hole and add the top dipstick, and if the tower is cast over you can machine it off and use the 914 filler assembly.

But it's usually a lot easier to use a 914 case. Or one of the VW applications that has the top filler and dipstick--there are some.

The 914 cases have engine numbers that start with W, EA, EB, EC, GA, GB, or GC. The GA/GB/GC (these are the 2.0 engines) numbers would be found in front of the oil filler. The other 914 engine numbers would be found on a boss on top of the case on the right side near the flywheel end.

Note that some of the VW cases have non-GA/GB/GC numbers in front of the oil filler tower.

Also note that W, EA, EB, and EC were also used in some non-914 applications. GA, GB, and GC were only used in 914s.
