Really? I thought the tiico's were accepting of the standard shaft somehow.
The reason i say this, is i just had a talk with a mechanic buddy who told
me a story about a syncro westy, with a tiico.
It was a long, long time ago, roughly last month, and it was a beautiful
westy, the finest syncro in all the land. Yet it had a driver that fueled
his habbit by throwing a TIICO in there, and throwing lots and lots of parts
at the TIICO as they broke (i recall seeing him replace the exhuast TWICE
last summer). Well as time went on, it seems his TIICO seized in one
cylinder, and blew up. In the process of self destruction, the little engine
decided to cut its own losses, and damage the soft coolant lines as well.
This is where the friendly mechanic got to learn about $700 coolant lines
that really "aren't all that special". The Westy's owner decided that the
TIICO wasn't for him, and they chose to put a 2.0 Jetta engine in there. In
the process, they found that they would have to use a 1.8 head for clearance
issues, and that even then, the decklid posed a problem. Furthermore, while
installing the 2.0 happily into the place of the now parted TIICO, the
mechanics discovered that the input shaft would need to be 'shortened
considerably', meaning that it had to be much shorter than that of the TIICO
engine. And then the engine roared to life and with a mighty caugh like a
mouse with TB, preparing to push an extremely heavy vehicle, the engine and
Syncro Westy lived happily ever after.
In the end he told me that "with all the headaches we went through, your
name came to mind and we thought about calling you. I told _____ this was a
common conversion, and Craig would either know or know where to find out
what was involved". This just proves the theory once again that with enough
time (at $70/hr) and a big enough pry-bar.....anything is possibly without
any forethought! Maybe thats the average mechanics silent rule?
A friday story of vanagons....
