oil pressure drop in left curves

[pharmacist]

I'm new here, from Switzerland, and the owner of a year 2000 Cerbera 4.5 left hand driven.
I went out for a ride this afternoon in the black forest and noticed a almost complete loss of oil pressure in left curves. As soon as the car kept going straight again the pressure came back to normal. I didn't try to do a left circle because I was afraid to damage the engine. There's enough oil and otherwise the car performes normally. I know about some possible reasons (kinked oil pipe, bad oil pump etc.) but maybe there's something special and typical I don't know about.

Where is the oil level sitting on the dip stick?

on the top mark

Mine has only ever done that, when the oil's low.

Mine does this when the oils low, I tend to keep it about 5mm above maximum on the dipstick.

From what I have heard the dipsticks aren't that accurate ??

Many of us do Spa, and Pouhon is the ultimate lefthander. I don't remember anyone having oil pressure issues. Are you an AJP8 or a Speed6?

Needs more oil.

[Mr Cerbera]

There is a known problem with the capillary action in the dipstick pipe.
To get a true, level measure, take the dipstick out, overnight, and measure the next day. I have found this to be more accurate.

Also, in my experience, it is almost impossible to adversely affect the motor by over-filling (as opposed to the reverse). She just blows it straight back out until she feels comfortable.

HTH

P.S. Where are you in Switzerland ? I fancy an end-of-year dash to the mountains

Thanks everybody. Obviously there is a big difference between cold and hot engine: about one and half liters. So there really wasn't enough oil.
I will change the oil and find out if the bearings were damaged when I look for metal rub off.

I dont think the hot v cold reading is that different (on an AJP). The difficulty is getting a good reading on the dipstick. To measure a hot engine you will likely struggle more.
