Looking from left to right, to see where oil tank is installed. Oil tank filler is easiest part to see. Porsche engine should be monitored with oil temp and oil pressure gauges. To right of cigarette lighter is one spot for them, although it is not in direct view of driver. Oil cooler is behind grill, but not visible in this photo.
Oil tank is just visible behind rear wheel.
It and the muffler are the only tipoffs that the van is not stock.
