Alle dieselmotoren in de T3’s zijn 4 cilinder in lijn, maar de benzine motoren zijn vanaf het begin al boxer-motoren geweest. Eerst waren het luchtgekoelde (lucht-boxer) motoren en later watergekoeld (water-boxer). Deze motor, de DJ, is de laatste variant van de water-boxers en daarmee ook de sterkste motor die in een T3 werd gelegd. Het voordeel van boxer motoren is dat de motor breed en laag is. De bus is er ook helemaal op ontwikkeld, een boxermotor past mooi in de motorruimte waarbij de 1600cc diesel motor bijvoorbeeld schuin komt te hangen. Deze is eigenlijk te hoog voor de beschikbare ruimte.

Mijn originele motor zag er wat… vies uit. Desondanks had hij het nog veel kilometers kunnen volhouden als ik niet het oliefilter er onder vandaan had gereden.
