I don't have a Bentley here in front of me, but my impression is that the flow in the late cases went: pump, rear valve, cooler, front valve, bearings, in that order. I could be wrong about that, because it's hard to follow the oil passages with the engine installed. It's rather interesting to try to map them all out with the engine out and the case all apart, because they don't all go where you expect them to. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
