+Tapping the discharge hole is another way of getting the excess oil back to the tank without running it through the engine first. \\
+The rear discharge hole was plugged and the side of the discharge hole was tapped with and 1/8" nipple. \\
+A hole was drilled into the top of the mount behind the internal cavities for a hose to run from there straight to the oil tank cap. ((photo by norseXL of the XLFORUM http://xlforum.net/forums/showthread.php?t=1458269&page=2)) \\
+With the cases apart, the vent / splash holes to the cam chest were enlarged and ported. \\

+The umbrella valve in the cam cover was removed and a larger hose fitting was added to use a reed valve for crankcase breathing instead. \\
+A windage tray was made with a 2mm thick aluminum plate to also act as a flywheel scraper. \\
+The front part was bent toward the fly-wheels after the pic below was taken. ((norseXL of the XLFORUM http://xlforum.net/forums/showthread.php?t=1833647)) \\
+The bolts are secured with Loctite (2701). \\

+Cam box oiling was also modified. \\
+A line was tapped into the bottom of the case so the oil level doesn't rise above the castings for the bolts to flow to the scavenge hole at the rear of the crankcase. \\
+Also an external drain was plumbed from the cam chest to the crankcase (under the windage-plate). \\

 This is an upgraded oil return to change the scavenge to the front of the engine. \\
 It also incorporates a modified 07 XL oil pump (modified by Charlie Karling of Karling Racing). \\

 The fittings are all stainless and they're thin wall so no I.D. has been lost. Its actually been opened up a bit. \\

 Here the the pics after bolting it up. \\
 Countersunk cap screws through the windage tray, through the factory tray, tapped into the mild steel underneath, where some extra material has been added to get a good ammount of thread area. And then at the back where the 90 degree bend is button head cap, threadded through the case out the other side, with a nyloc nut on the other side with plenty of Loctite 243. \\
+You can see the grooves cut into the trailing edge of the windage tray. \\
+<blockquote>I was watching Discovery channel about the barn owl, fascinating creatures, anyway they hunt at night and their prey relies on sound as a warning, so the owls have had to adapt to become silent fliers. To do this their wings trailing edges are not smooth like most birds, they are jagged and the feathers at the edges are rough. This lessens turbulence and vibration, which means no noise, and silent killers! Anyway it took about 10 minutes to do and I think it helps.
+My main concern is the oil not draining from the cam case, but I've got the tie bar to tap into if I have to.
+I also met a guy who (who is a glass blower) and makes all kinds of stills and refiners and what not for high spec chemical experiments etc. He has made me some brass fittings with a rubber o ring to hold a glass tube in place that he is blowing for me. Making two, both 19mm OD, and one of 14mm ID, and one with 11mm ID. He reckons it will be strong enough. Not sure if I trust glass on the open road though.
+But... will you be able to see anything, or when the motor is running will it just turn cloudy brown? If you shine a torch you can actually see the scavenge point inside the cases, through the tube. That would be nice to see with the engine running. Doubtful though.</blockquote>

+Below, the last bit for the cases is done includeing the glass drain. \\
+A straight piece bent 90 degrees was tried but it meant the outside of the bend was thin. \\
+So the guy got a straight piece of glass and cut it at 45 degrees then welded the two pieces together to make a 90 degree bend. \\
+The flywheel scraper was originally set at .015" from the flywheels but it was later moved slightly farther away. \\
