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.

The "TPS" was used as an early emissions solutions.
On the 914-6 it was a set up that used a vacuum positioner to kept the throttle open for "over run" What is throttle overrun? Over run is where the throttle is fully closed and the engine is slowing down. Rory's second picture shows the vacuum pot. That's also why the original 914-6 DR side intake manifold had the vacuum ports. Also the throttle cross bar was unique having a fitting to connect the vacuum pot. |
