The reason is that the type 1 engine draws its cooling air from the space around the top of the engine, but this space is sealed off from the underside where the hot air is exhausted. This system works fine, but you need ALL the parts to make it work. If you leave the seals out so that hot air from the underside of the engine can come up and be run thru the engine again, then the engine will overheat and will quickly die. In the type 3 engine compartment there is no provision for sealing off the top side from the underside, so this just won't work. Instead, the type 3 engine draws in cool air thru a bellows that provides segregated cool air for engine cooling. The point is that one way or another you have to keep the incoming cool air separate from the outgoing hot air. If you don't to this you will waste your time and a perfectly good engine. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- Too much?
