It is the stock plug with a 3/8 inch hole drilled in it. Then weld on a steel elbow with the AN size of your choice. I used AN 6 if I recall correctly. The steel elbows are available form Pegasus racing, Earls and other places I'm sure. The one that I used was a steel AN6 and pipe thread adapter elbow. I cut off the pipe threads and butt welded it to the drilled stock plug. It's not hard to do and not expensive.

I read somewhere that the factory used a cooler to spray directly on the gears to keep the gears cool. Maybe I got something mixed up, but wouldnt an arbitrary location kinda defeat the purpose of an oil cooler? I know you're cooling off fluid, but will it really effectivly cool off the gears? And what do you use to pressurize the fluid?

916 boxes had spraybars and an internal pump IIRC and in Iamchappy's pics, you can see his electrical oil pump. |

Yes, a spray bar is most effective but understand that the pictures displayed only show the output side of the loop. From the drain plug area the hot oil goes to a pump and cooler then returns to the gearbox. The return can be plumbed to a spray bar over the gearset. In my case, I drilled and tapped one hole over the ring and pinion to dump the cooled oil. Next time I have the gear box apart I might tap 2 or 3 more holes over the gearset for additional cooling. |
