Recently had my 914-6 engine rebuilt,upgraded to a 2.2 with an E cam,the oil pressure light is on while the car idles,soon as you rev it a bit the light goes out till you're back to idle,what could be causing this
Thanks Brian
At what Oil Temp is it coming on at Idle.
IIRC it comes on at 7psi, so below what should be normal oil pressure for a fresh motor, unless the motor is running warmer than normal, say above 230.
I'd be concerned. Low oil pressure can be a sign of main bearing problems. That's not set in stone, but I wouldn't be happy to see that on a fresh rebuild.
One common mod is to use a later oil line adapter with a smaller orifice, which helps raise the oil pressure.
what pump is in it ?? the factory pwners manual states at elevated temps light may flicker..
what rpm is idle ??
replace the dual sender with a single red plastic oil pressure sender,,, by the oil thermostat
Also, if you have a LED it will look much worse than it is. When the light stays on over a low idle I'd be concerned.
What viscosity are you using. Maybe too thin?
I run 15W50 in my type IV. I tried 10W40 once and every time the engine was at idle RPM the oil light would come on. Went back to 15W50 and no problem.
