Porsche - Preventative Engine Repairs to Avoid Engine Replacement


When it comes to ensuring that your Porsche has a long and healthy road life it is critical that you follow the manufacturer's service calendar. This guide includes the mileage points or recommended time frames for all of the vehicle's required preventative maintenance needs. In most scenarios, having these services completed on time will do a more than satisfactory job of keeping your Porsche running and driving its very best. However, there are other issues and services that you should be aware of, as being mindful of them can further protect the engine from major failure.

Replacing Variocam bolts

Many current German automakers, including BMW, Mercedes Benz, Audi, VW and Porsche, utilize computer controlled variable valve timing (VANOS in BMW, VarioCam in Porsche), allowing for a perfect balance of power and fuel efficiency based on driving conditions. In the latest Porsches the VarioCam system continuously varies the timing of the intake valves by adjusting the tension on the timing chain connecting the intake and exhaust camshafts. In some Porsches there have been instances in which the camshaft controller bolts have come loose inside the engine. This can trigger the check engine or service engine soon light, and furthermore, result in an engine stall or more drastic engine damage. In June 2017 Porsche issued a recall for certain models as a result of this problem. Contact your local Porsche service center to find out if your Porsche has been affected, if it has, do not hesitate to schedule a VarioCam bolt replacement service. BMW issued a similar recall in 2014 for bolts securing the VANOS unit.

Proper way to add coolant

If you receive a service message in your Porsche warning of low coolant levels you may need to add more to the reservoir. First and foremost, do not open the coolant reservoir when the engine is hot. Provide your vehicle with sufficient time to cool down. Ignoring this warning can lead to the pressurized coolant reservoir spraying hot coolant when the cap is removed, resulting in burns. To properly add coolant to your Porsche follow this guide:

  • 1. If the engine is at all warm, cover the reservoir cap with a cloth and open cap carefully to allow any overpressure to escape. Then unscrew cap completely.
  • 2. Read off the engine coolant level. When the engine is cold and the vehicle is completely level, the coolant must read within the area between the min and max markings on the reservoir.
  • 3. Top off with coolant as necessary. Only add an equal mixture of antifreeze and water. Use 50 percent Porsche approved antifreeze with 50 percent water. Do not exceed the max marking.
  • 4. Tighten the cap on the reservoir until it locks securely.
If you're losing coolant you will need to contact a professional Porsche service center to identify the problem. This is an issue that requires immediate repair to prevent overheating and engine damage.

As with any vehicle, Porsche's require routine maintenance and the occasional unscheduled service. If you have any performance or drivability issues with your Porsche be sure to contact your local Porsche repair and service center right away.
