I've been curious about those JDM engines with the oddly placed heater hoses. The Wikipedia entry on the 5VZ-FE informs us that the engine was used in the Toyota Granvia, a minivan. A bit of Internet searching turned up the photos below, of a Granvia sale, from an Australian web site. The first, obviously, is of the car's engine. It's clearly a 5VZ-FE, and the heater core is in a very different location from 4Runners and Tacomas, the 5VZ-FE equipped vehicles most familiar to Americans and Canadians.
The 2nd photo is from that same vehicle's cabin. It's not clear to me that the engine cover comes off - it might - allowing access to the spark plugs and what not.
It's easy to imagine that this vehicle's engine, positioned as it is in a minivan, needs to have the oil filter in a different location. Also, as the eBay engine shows, the Granvia engines are not equipped with an oil cooler. Instead, that location is capped off.
Given the 1st photo showing the engine sited far back in the bay and under the dash, and not knowing how much cabin access is available, let's hear no more complaints from North Americans about spark plug changing and valve cover access on this engine.
Finally, you can read 2 Wikipedia sites for information on why these JDM engines exist.
