… this is not about a 914 but is about our 1977 911S Targa 2.7L
Took her in to have a bad ground fixed that was blowing a fuse on the clock/lighter circuit. While being serviced we had an oil change done although it didn’t really need it. We had 10L’s of Motul 20/50 added and new filter. While driving home I noticed that the oil pressure during throttle was almost pinned. When we got home (2 miles) the oil reading on the gauge at rest on level ground was just above the low line. This morning we moved it on the lift for winter storage and noticed a small puddle of oil, which never happens with this car. I cleaned the undercarriage and will see in the morning. Any ideas? |

Was the oil level checked with engine warm, thermostat open, idling on level ground? Ten liters including filter? Is the engine stock?
FWIW, I have a '67 911S and a '68 T and both show nearly zip oil pressure at idle when warm, but pressure rises appropriate to RPMs. |

When measuring oil it was warm, at idle, and flat ground. Not sure how modified the 2.7 is but appears stock configuration. |
