Professional Porsche Intake System Cleaning in Oakland

Do you have difficulties with accelerating your Porsche? Does your car vibrate, or does it consume more fuel than before? If yes, you can bet that carbon deposits on your intake valves could cause the problem. In a Porsche engine, the intake valves are parts situated in the cylinder head and are responsible for air (or air/fuel mixture in some cases) into the cylinder. These valves open and close in relation to the engine’s camshaft and ensure that the necessary amount of air for combustion is allowed into the cylinder.

In the long run, carbon can build up on intake valves, particularly in direct injection engines used in most Porsches. This buildup causes a reduction in the airflow, resulting in poor performance, rough idle, misfire, and poor fuel economy.

What Causes Carbon Buildup In Intake Valves?

• Oil Blow-By from the PCV System: Your Porsche’s Positive Crankcase Ventilation (PCV) system is designed to control emissions by routing oil fumes from the crankcase back to the intake manifold. However, some of these vapors condense on the intake valves and cause carbon accumulation on their surfaces. This problem is most often observed in high-performance engines expected to run at high revolutions per minute.
• Direct Fuel Injection: Another feature common in most Porsche engines is the Direct Fuel Injection (DFI), which enhances power and fuel economy. During the engine operations in conventional fuel injection systems, the gasoline rinses the intake valves to remove any deposits, if any. However, in the direct injection system, fuel delivery is done by spraying fuel directly into the combustion chamber. As a result, the intake valves do not enjoy the cleaning process found in normal injection systems. In the long run, the oil vapors, fuel residues, and other particles cling to the intake valves, creating thick layers of carbon.
• Short Driving Trips: If you use your Porsche mainly for short rides, the carbon buildup will likely accumulate more quickly. Short trips do not enable the engine to warm up to the optimum temperature that would enable it to combust residual fuel deposits and oil fumes. This causes deposits to build up on the intake valves over time.
• Low-Quality Fuel: When using low-quality gasoline, one is likely to have more carbon build-up within a short span. Premium fuel usually has detergent that assists in the removal of deposits, while low-quality fuel lacks the necessary cleaning agents, and as such, more deposits build up.

Ways Of Addressing Carbon Buildup Issues in Porsche Intake Valves

• Walnut Blasting: One of the most useful methods of cleaning carbon buildup on intake valves is walnut blasting. This process entails using crushed walnut shells to remove the deposits without damaging the engine’s parts. A professional technician will remove the intake manifold and clean the valves using special equipment.
• Engine Care: Failure to change the engine oil frequently and perform other maintenance procedures at the right time may contribute to carbon buildup. Using the best quality synthetic oil can reduce the blow-by, while regular fuel system cleaning can also prevent the accumulation of excessive carbon on the intake parts.
• Speeding Up Once in a While: If you often drive your Porsche at low speeds or for short distances, it is beneficial to occasionally step on the accelerator and go faster, though not excessively. This can assist in the burning of the accumulated carbon and ensure the intake system remains clean.
