Could the owners of 2L Mi16's please tell me if they have a vacuum pump on the end of the inlet cam?
I'm a bit confused about which XU10J4 engines have the pump and which don't. For example, the engine below has a plate covering the area where the pump attaches. It's from a 2L Mi16 which I used to own.

Magic was also kind enough to lend me an inlet cam from a local Australian delivered 306 S16. You'll notice that it has no drive slots for the pump, nor does it have the cross drilling for lubrication. I doubt it had a pump.

The other pictures show an XU10J4 cam with the drive slots and the oil hole. The other cam in the picture in a reground XU9J4 inlet cam with a 2L reference tang pushed on.Click to view attachmentClick to view attachment
Also shown is an XU10J4 with the vacuum pump.

I can't find any info on the Parts CD for pump, either for a 306 or 405.
If anyone can shed some light on this it would be much appreciated.
