Hi guys,

I installed recently an oil pressure gauge in my vanagon (air-cooled 2L
1983)

in a hot day (100F) , my (very annoying ) alarms triggers all the time
when I am idling. the pressure is less than 5 PSI for an oil temp of
250-260F.

I notice that the oil pressure really diminish over oil temperature
which is normal but I am wondering if I am within the spec .

When engine is cool , I have a PSI of 45. I have 20PSI around 240F when
the van is cruising at 60-65MPH, it goes down to 15PSI at 260F while
cruising at 60-65MPH.

I think my oil pressure is too low , What do you think ? . Do you think
my oil pump is guilty ? , I went cheap by not replacing it when I
rebuilt my engine.

Do you also think that the low oil pressure could  be the reason why I
have noisy hydraulic lifter when the engine is cold.

Thanks for any feedback

Chris
