Half of that case is now the Evil Engine.
Would you believe a guy who knew you sent me that case called me up and wanted me to cut the serial numbers out and send them to him to weld in his case? Needless to say the case half is still on my shelf. Unbelievable.

That is a 901/01 engine, the first production 911 engine.

A few telltale items: centerlubed cams, forged rockers, finned lower valve covers, oil rings below the piston pins, short rocker shafts. And a set of Webers, no doubt installed after the factory retrofit them to Solex-engines!

This cutaway makes us SWB guys beam with pride. :)

John,

It has been 20++ years since I have seen this engine.

I think it is pieces (mostly) from the first 100 or so 901 engines, perhaps some prototypes. There are some startling differences. One of the most significant is the attachment of the chain housings to the case. Note the studs both along the crankshaft axis (violate arrows) and the ‘normal’ one perpendicular. Even the tin attachment to the chain housing was different.

You are correct about the cam oiling but notice how the cam oil line is forward under the heater tube.

Note the different oil cooler. The big hose attached way under the cooler (green arrow). You have to remove the right heat exchanger to get to that fitting.

Note the different tensioner idler arm (yellow arrow). Even the crank pulley is stamped as are period VWs (green arrow). Different engine mount and mounting (another yellow).

On the transmission cutaway, note the109-tooth ring gear and the difference in the input shaft adjacent to 2nd gear. Yes, the starter is different. Not only is the pinion different number of teeth but it has a ‘nose bearing’ that is integral to the starter (again like period VWs).

I recall this engine having the early (Corvair-like) heat exchangers. Of course the Webers are 901/05-like from much later. I would love to disassemble a virgin one of these and document the subtle (and not so subtle) differences.

When was this cutaway first displayed?

Best,
Grady
