Oil Pressure

[beershark]

Hi,

I am new to my 997 S and wondering what other peoples experiences are of the oil pressure.

I believe the manual states it should be around 3.5 - 4 when driving, mine seems to be constantly up around 4.5 / 5 when driving as a steady pace on a road at a reasonable speed.

It also seems be at a similar level when idling.

Oil level is fine, 1 bar off max according to the screen.

Is this normal.

Also, maybe related on the odd occasion when starting up in my garage there seems to be a lot of smoke on start-up and for several minutes afterwards.

When its warm, no issues. I had a 996 that I took to 123,000 miles recently and there wasnt a hint of smoke on start-up - even if it was left for weeks or months.

Thanks,

Rob

Rob, All that sounds quite normal and shouldn't give undue cause for concern, but take a look at this thread for more info. [link=http://www.porscheclubgbforum.com/tm.asp?m=800271]http://www.porscheclubgbforum.com/tm.asp?m=800271[/link] Blue smoke on start-up seems to vary between individual vehicles but if excessive and you're using a lot of oil, it may indicate engine wear or defect. Official oil changes are every 2 years, but many of us feel this is overly long for a high performance sports car and therefore change oil and filter each year. 0W-40 or 5W-40 are the recommended viscosities, which with a new filter should give the correct pressure. Regards, Clive.

Hi rob As Clive says , sounds normal For reference my C2S gen 1 was low mileage ( under 24k when i bought at 6 yrs old) and always seemed to run at nearly 5 bar- I took it to my OPC twice as I was concerned as you are and always was told by the technician that high pressure such as this is fine I do notice my Gen 2 GTS usually runs much lower but it is a different engine type and DFI Sounds ok

As per comments above probably normal, however, when the oil temp is above 90 deg C you should be able to see the oil pressure increase as the engine revs increase from idle to 3000rpm when it will level of at the 3 to 4 reading. I had an intermittently faulty oil pressure sensor that caused a reading of 4 to be seen regardless of how low the engine speed dropped. Convincing the OPC that I had a problem was tricky as they initially claimed that without seeing the problem for themselves they couldn't submit a warranty claim. Their suggestion that I leave the car with them until the fault manifested itself on a test drive didn't appeal to me so with a little persistence they eventually accepted a photograph of the instrument display as evidence.
