I've got a new (to me) '87 Westy of indeterminate history.  While
looking at the top of the engine today I noticed 2 yellow decals on the
block that read as follows.

First:
EXCHANGE
PIECE REMISE A NEUF

Second:
Volkswagon Canada Inc.
Remanufacturing
Remise a neuf
Engine # 08796

I'm hoping the local VW dealership might have some info but they're
closed until Monday.  Can I infer from this that the engine was rebuilt
by VW?  Assuming the work was done by a VW shop, is there another way to
find out it's history?

I'm not even sure the motor is original.  Where can I find the VIN
number on the engine?

Thanks,
Darren.
