Is there a difference in a 2.0L out of a bus as opposed to a 2.0L out of a 914? I was under the assumption that a bus engine had different heads. I don't know where I heard that. Maybe I just made that up.

Another difference, the bus cases for the carb'd engines have a bronze sleeve that goes 'through' one of the oil galley holes by the flywheel end, for the mechanical fuel pump pushrod. When you plug those holes in the case, you have to leave that one alone as going through it will screw up your oil pressure.
Besides blocking up the pulley end flange for the oil fill, you have to block the flange for the fuel pump also. The finish on a bus case isn't as nice, also, like more casting marks, burrs, not as shiny. Some bus cases don't have the slots to put in a windage tray, even, but some do. The hardest part I would think would be making the hole for the tube to check the oil level, as bus cases don't have that steel tube coming out the top. |

All the 2.0 bus engines I've seen were injected, mine didn't have the fp mount. Capn would know for sure. |

The 2.0 busses were all fuel injected so they would have had electric fuel pumps and that flange not broached. Something else not mentioned previous, but bus 2.0 cases lost the oil control valve (I think it's called that - the one below #1 cylinder) on account of the hydraulic lifters. I think 914 cases all had it as they all used mechanical lifters. |
