Information
- Engine oil pressure may be too low for a number of reasons:
- Oil is diluted.
- Oil pump is faulty.
- Too much bearing clearance.
- Oil level is too low.
- Oil pressure-regulating valve is faulty.
- Incorrect oil has been used. Only use oil that has been approved by Porsche for the measurement.
Information
Test conditions for checking engine oil pressure
- Correct engine-oil level
- Engine oil temperature approx. 80°C
- Engine oil pressure only variable at a mileage of 1, 000 km (621 mls) or higher. When the mileage is less than 1, 000 km (621 mls), the oil pump always delivers the maximum possible engine oil pressure (optimised running-in behaviour).
- > V.A.G 1342 - Oil Pressure Tester with adapter must be screwed into the bore on the oil pressure switch. > Tightening torque 20 Nm (15 ftlb.)
- Screw oil pressure switch into > V.A.G 1342 - Oil Pressure Tester and plug electric plug connection into the oil pressure switch.
- Connect electric wire harness for the oil pressure tester and switch on the oil pressure tester.
Information
To check the engine oil pressure, the catalytic converter must be re-installed, while the > V.A.G 1342 - Oil Pressure Tester remains connected to the engine.
- Start the engine.
- Check engine oil pressure.
- Engine oil pressure at idle speed: > Overpressure 1.5 bar
- Engine oil pressure at 1, 500 rpm: > Overpressure 1.9 bar
- Release and disconnect electric plug connection on the oil pressure switch and unscrew oil pressure switch from the > V.A.G 1342 - Oil Pressure Tester .
- Loosen adapter and remove > V.A.G 1342 - Oil Pressure Tester .
