| WARNING | Engine oil is toxic. Danger of poisoning! |
> Do not consume food or drink while working (danger of mixing).
> If swallowed, observe the warning information on the containers, contact a doctor if necessary and show the information on the containers.
| WARNING | Danger of scalding from hot oil! |
> Engine oil and components of the oil circuit can become very hot!
> Allow engine and components to cool down.
> Avoid contact with the skin and eyes.
> Wear suitable protective clothing.
| WARNING | Oil is combustible! Risk of fire due to oil and hot components (exhaust manifold, etc.) |
> Do not pour engine oil over very hot components (e. g. turbocharger).
> Never place cloths soaked with oil on hot engine components.
> In case of fire, use CO 2 or dry powder fire extinguishers.
Note. The oil pressure may be too low for a number of reasons: Oil is diluted. Oil pump is faulty. Bearing clearance is too large (e. g. crankshaft bearing). Oil level is too low. Oil pressure regulating valve is faulty. Incorrect oil has been used. Use only oil that has been approved by Porsche for the measurement.
Note. The oil pressure switch is located in the oil filter housing/engine support arm.
Note. When the oil pressure switch is unscrewed, approx. 0.3 litres of engine oil escapes.
Scheme 15
1. Remove oil pressure switch/sender. > 170419 Removing and installing oil-pressure sender - section on "Removing"
2. Use adapter insert 4 and tighten by hand with suitable sealing ring instead of oil pressure sender/switch.
3. Connect pressure gauge to hose.
Note. The oil temperature must range between 80°C and 100°C when performing the measurement. Check the oil temperature using a special thermometer or the PST II tester.
4. Start the engine and move off at the required test speed. Read off the oil pressure on the pressure gauge while doing so.
| Engine speed [rpm] | Oil pressure [bar] |
|---|---|
| 600 | 1.0 |
| 2000 | 3.0 to 5.5 |
| > 2000 | Up to max. 7.0 If an oil pressure of more than 7 bar is reached, further diagnostics is necessary => Pressure relief valve in oil pump may be faulty => Replace oil pump |
Note. When the pressure gauge is unscrewed, approx. 0.3 l of engine oil escapes.
5. Remove pressure gauge with test hose. Collect the emerging engine oil and dispose of it in accordance with the applicable national laws.
6. Install oil temperature switch with new sealing ring. > 170419 Removing and installing oil-pressure sender - section on "Installing"
