Every thing seems fine, start up, warm up all good oil pressure reading. But after a while at idle the oil pressure gauge is almost nothing. Running 20-50 valvaline for brake in. Should I go to straight 60 wt race oil. This car is mostly a track car, or when driven on the street it likes the 5 to 7,000 rpm range. Not a cold weather 914. Thanks, Mark

Must be Racing Clearances ..Haha, general rule is 1 bar per 1k rpm,,we a carrera the othe day same way as yours,, But it has a ton of miles on it.Cut filter open and monitor,,at this point 20/50. Oil analysis.
Unknowns are always a gamble...Ask Eric Shea about his 2.5.. almost a total failure, before rebuild..really nasty rod bearings.. 3 bar 4 bar oil pump ?? all makes a diff. ..shiny inst always best.. |

I believe 10 psi per 1000 RPM is the rule of thumb.
I think it's not uncommon for early motors to have essentially 0 oil pressure at idle. I recall my parents' 1970 911 did that when the oil was hot. Perhaps more likely if it has an early oil pump. Not saying it's ideal, mind you. |
