As part of my GT look alike project, I spent quite a bit of time on the oil system. Here's the link to the overall project thread:
http://www.914world.com/bbs2/index.php?act=...=ST&f=2&t=34896 There's several good threads on the site about coolers. I started one, soliciting opinions about a possible oil cooler to use. I must say I had not done a search before starting that thread. If I had, I would have found a lot of the information I was looking for. see: http://www.914world.com/bbs2/index.php?act=...=0entry529632 I've decided to move away from the solution I was exploring there, which involved Porsche 928 transmission oil coolers and instead to use an Rx7 cooler that I will modify and then have ultrasound cleaned. Actually, all the parts below will need a super-thorough cleaning before the engine starts, to avoid contamination. There's a place in town that does ultrasound cleaning, and that appears to be the best route. I have also started a thread on the hard oil lines, and tub modifications to make room for those. See: http://www.914world.com/bbs2/index.php?act=...=0entry529632 I have'nt sourced the hard oil lines yet. In any event, I've done a lot of work on assembling a GT style oil system for my car. Here's an overall view of the part of the system in the engine compartment: |

Detail of the console area:
The threaded hole on the console that faces towards the middle of the engine compartment, just above where the oil filter goes, is not used and will be plugged. Attached image(s) |

The spacer can barely be made out in the preceeding picture, between the black console and the oil tank.
Here's a closer view of the console. Spacer cannot be seen here, hosever: Attached image(s) |

On the underside of the car, the oil lines that will attach to the hard oil lines, and the one (furthest) wich is the oil return line, from the engine:

I had to drill a couple of 1 and 3/8 inch holes in the driver side shelf to let oil lines through. (the hole furthest away is on all cars):

Finally, I fabricated the pop-off valve that attaches to the oil fill neck. Here's a few pictures.

Finally: I have yet to test the pressure at which it opens, it should be around 80 psi. If I'm off a little, I can adjust it. I used the fittings from a junk engine case that still had them.

Is that a 72 911S console?

It's a '69 S console. I think that the '72 part is completely different, that was the year the 911 had the tank in front of the right rear wheel. The part I have is actually magnesium, very, very light. |

I can't quite see the route oil takes...does it pass through filter and then through thermostat?
Why is the oil return line connected to filler? |

I ran a test to see at which pressure the pop-off valve would open, and it was too high (above 100 psi). So I figured out a way to make the valve adjustable. A longer lollow end screw, and a jam nut:
