So, when ordering parts it is only necessary to know the year and model of the vehicle. The only other significant change took place in 1978 with the introduction of hydraulically adjusted valves via hydraulic cam followers instead of solid ones. In 1976, the engine size was increased again to 2.0 liters (71mm stroke, 94mm bore). In 1975, the displacement increased to 1.8 liter (same stroke as the 1.7 liter, but larger 93mm piston), and carburetion was dropped for electronic fuel injection across the board. The 411/412 and 914/4 were electronically fuel injected, while the Bus had twin carburetors. The first TypeВ IV engines up to and including 1974 were 1.7 liter (69mm stroke/90mm bore). That is why many peopleВ incorrectly refer to the laterВ Buses and VanagonsВ powered by the TypeВ IV engine as 'Porsche powered.' It was, in fact, the other way around: the Porsche 914 was 'VW powered.' Unlike the TypeВ I engine, this engine was never made with an up-right fan shroud, but rather only in the flat pancake design similar to the one used on the Type III. This basic engine was used not only in the 411/412s and Bus (from 1972-on), but also in all air-cooled Vanagons from 1980-1983, and in the Porsche 914/4. It is referred to as aВ Type IVВ because it was originally designed in 1968 for-and fitted to-the VW 411/412, the fourth type of vehicle VW made and thus referred to as the 'TypeВ IV.' This too was a horizontally opposed four cylinder engine, just larger inside and out. In 1972, the Bus switched to the 'Type IV' engine. So when VW parts people, books, or parts catalogues refer to an engine as Type I, II, or III, they are referring to the entire engine assembly, not just the long block.

TheВ Type IIIВ employs a rather flat 'pancake' cooling system design, while the Bus and Beetle use an up-right fan shroud system. For example, the Beetle uses twin tail pipes and corresponding muffler, while the Bus uses a single exhaust pipe and corresponding muffler. However, as suggested above, the cooling, intake, and exhaust systems all vary a bit between the models. no cooling, intake, or exhaust systems), theВ Type IВ (Beetle/Karmann Ghia),В Type IIВ (Bus up to 1971), and TypeВ III (Square-back, Fast-back, and Notch-back) they all use the same basic engine. While it is true that if one were to disassemble any of these engines down to the 'long block' (valve cover to valve cover, flywheel to pulley-i.e. These were four-cylinder horizontally opposed ('flat-four') engines introduced in 1948 at 1100cc and 25hp, and evolving to 1600cc and about 58hp in 1971. The Bus used the same style engine as the Beetle up to and including the 1971 model. It is called that because it was introduced as the second type of vehicle VW made, the first being the Beetle (and why it is referred to as the 'Type I'). Wondering if you'll get your money's worth? This video is complete and consistent with Rick's thoroughness in the first 2 volumes of his video series.Here is a quick article designed to de-mystify the VW 'Type' designations. Wondering if it's easy to follow? Rick moves at an easy pace, explaining each step along the way. Wondering about the picture quality? It's excellent due to being shot, edited, and mastered with cutting edge digital technology giving it outstanding clarity. Wondering what tools you'll need? He'll tell you

You'll feel as though you're next to Rick and he's you're personal friend, sharing trade secrets that he's picked up in over 35 years of experience exclusively on air cooled VW motors. Rick and his two sons will walk you through the whole process in an orderly way starting from the motor just as it comes out of the car to a completed running motor ready to be installed. IF you've been hesitant to tackle something this big this video gives you not only all the information but the confidence and support you need to do the job right. 38-min video includes complete tear down, Inspection, and reassemble. Volume 3 is a complete engine rebuild video on a 1600 dual port, 1500, and 40 hp motors and all the important differences.
