Is this a correct Oil Cover Lid for a 1970 914-6? It appears to have a threaded port for a temperature or pressure sensor / switch. I can't find that part number in the 914 or early 911 parts catalogs.

Original equipment on our cars was a temp sensor switch (in pics) that activates a throttle position arm on the throttle shaft (using a vacuum pot and hose from from the 1-2-3 intake)and opens a fuel valve that feeds squirters in the OE air filter housing.
At least that's the way I think it works. Usually eliminated (maybe by Porsche service update) due to frequent fires. Not too many cars still have those parts. Not too many OE air filter housings are not melted. |
