Griff 4.0 precat oil pressure

[Greg M]

Afternoon chaps.

I've just replaced the sump gasket, oil and filter. Car is showing around 17psi at approx 900rpm, going as high as maybe 25psi at...say...3500.

What should I see on the gauge?

I've used around 5l of 10w/40 - maybe a smidge under, allowing for spillage. I can't check the level as the dipstick is broken/tube squashed. That's a job for when the outriggers are done.

Mine displays about 25psi at 900 rpm idle when warm and heads up towards 50 at 2500 rpm. I think oil capacity is 4.5 litres + 0.5 litre for filter.

Was your oil pressure different before the recent work?

You want more like 6.5ltrs in it.

5lbs of gunked on sludge saves a couple of litres

The oil pressure sensors do not seem to last long and may be giving you an incorrect reading, they quite often start leaking before failing. I am not convinced that a Litre less oil would affect the oil pressure, but it does need topping up.

A garage should be able to check your true pressure (if incorrect)with a subsidary guage.
