Replacement cases
These cases were VW engine cases that were sold from VW but never issued in an actual production vehicle.  All are dual-relief cases with 100mm oil passages.
Example:

Information from a 5/73 USA service bulletin issued 5/73:
Engines with the re-manufactured symbol, a letter, a number and ending with X, indicates a VW Exchange engine.  Before Oct., 1968 the X was not stamped onto the block.

From April of 1972 Shortblocks were sold with the VW remanufacture symbol followed by a letter. No numbers were used, you were to stamp in the old engine number.
 
F1 1300/1600
F2 1300/1600
DO 40hp if last digit is "X"
D1 40hp part
AD 1600
AK 1967-1974 1500/1600
AM 1600
AS  Sometimes seen listed as Super Beetle case for 1973-onward

 

Exchange engines
These engines are normally marked with a VW recycle symbol and an X at the end.
Example:

Information from a 5/73 USA service bulletin issued 5/73:
Engines with the re-manufactured symbol, a letter, a number and ending with X, indicates a VW Exchange engine.  Before Oct., 1968 the X was not stamped onto the block.

100mm oil passages? Wow! That's a lot of oil space.


It's an insane world out there... and I'm proud to be part of it!

I know this is an old post, and my question kinda dumb, but I have an AD case. Is that a good thing?

Just wanted to add that AM cases were also factory engines for some/all 70's Things 1600 cc.  I know this from several Things that were sold by our local dealer back when I was still in high school...Beetles had AH but Things had AM codes...

Sounds like a 73 beetle motor: http://www.thesamba.com/vw/archives/info/bugchassisdating.php , is it 6 cylinder, or 4?

It's a 4... And clearly a vw engine. Lots of crome on it is all.
Car has front disc brakes and is in vary good shape. Not sure what it's worth but he's asking 3900?

that was an interesting thesamba posting
I bought a VW powered ski hill tag line system 30 + years ago
it had a 36 hp. engine hooked up to a type 2 split case transaxle with one brake drum bolted to a solid arm on the mount.

I'm not sure if this "E" engine was the one or not that powered it- I have a few other 36 hp. engines
thanks
Hank
