914-6 Oil tank and network options, Solving out a wrong oil setup Options

[ManuFromParis]

Hello guys,
I've just imported this 914 from the US in France.
See pictures below.

It came with a 1971 911 2.2T on Webers, but the car never really worked or rolled when I got it : many issues everywhere.

The wire loom would have to be remade, likely from the ground up, but that could wait a little, since it's working as is.

I sorted out some wire issues with headlights, gas leaks on webers and then looked at the oil network, which did not look that correct.

First, there is the tank which is a modified 911 that went in left fender likely with a hammer or foot kicks, bending the fender and making it almost impossible to remove. I eventually did, but that was a pain. The fender suffered again and has now to be rectified.

I have several questions :

1. The oil cooler still is from the 911, so with an in-line intake connector, which implies a 90° adapter hose that stays very close to the left rear trailing arm. Frightening, but looks ok.

This cooler is pretty expensive, does the OEM 911 oil cooler could be modified to get the inlet with 90 degrees, as the 914-6 cooler is ?


2. There was no way to drain the oil except from the strainer plate's draining screw or unfitting a hose. As the PMS or OEM 914-6 oil tank doesn't have a drain screw either, how are you supposed to drain oil with this setup ? Add a T connector to the input cooler hose ?


3. The in and out hoses, and breather hoses were apparently correctly fitted, even though they went all strange ways. It was custom hoses and I wonder if I could use the standard return 2.7 oil pipe : 93010774111, then add a small hose to connect to the tank.

4. is it normal that all oil from tank fall down in engine cases when car is parked ? Does it fall down likewise on 911 ?


Would love to see picture of your setups or links to built reports.


Thank you for your feedback !!

The cooler can be modified with a 90 degree fitting, it is done pretty routinely. If you have a hose that is working, you are probably fine.

It is fairly common on a stock six to modify the coupling fitting between the oil tank hose and oil cooler hose by drilling it and tapping it for an M6 bolt that will serve as an oil tank drain. Since it is impossible to know what your hose configuration is, it is impossible to know whether you can do this on your setup.

I do not believe that the stock 911 scavenge hard line is a very good one to use on a six because it turns the return fitting away from the tank. It is possible to put an AN adapter in the scavenge out port on the engine and run a flexible braided AN line back to the tank.

As Ben said, the only thing between the oil tank and the engine sump is the oil pump. The oil level in the tank is higher than the sump. Oil will seep through the pump into the cases when the engine is not running. In your case, the tank shape may hold the oil even higher than a regular 6 tank, making this a bigger problem than normal.

Good luck sorting this out. I Do not know too much about the configuration of the 911 oil tank (and I think there are various configurations) but the 911 tanks are not commonly used on 914's. If it were a good idea, I suspect you would see them more often.
