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.

QUOTE(johnhora @ Sep 5 2022, 07:39 AM)  914-6 intake manifold with vacuum ports Very interesting! Thanks for the visual aids. Do you know if those ports were threaded? Our engine was missing the carbs. What we have now is a set of Zenith. The intake manifold has openings, but they are are not threaded.  |

Dennis those carbs and manifolds are from a '70-'71 2.2 911T Two year only combination. Not drilled for the vacuum ports....but could be. How serious is your restoration ? Those manifolds will be just fine on your 6 unless you insist on the absolute correct parts. The only difference is the vacuum ports which you will likely never use. |

Reviving this dated thread, as I've gotten some time back with the car to make progress on the engine. Also got rid of the Zenith and obtained the correct Weber IDTP carbs. If I follow correctly, the most original thing to do would be get correct manifolds with threaded holes and hook up a vacuum system of questionable safety with a sensor in the breather lid. The practical thing to do is put rubber plugs in the unthreaded holes of our existing manifolds and find a short bolt and washer to plug the threaded hole in the breather. Do I have that right?   |
