Engine M28.47

Symptoms:
- Rough idling and hesitation during acceleration
- Oil leaks around the valve cover and camshaft seals
- Overheating or inconsistent engine temperature
- Loss of power or poor fuel economy
- Engine misfires or backfiring

Diagnosis:
- Inspect for oil leaks at valve cover gaskets and camshaft seals, common wear points on the M28.47
- Check ignition components including spark plugs, wires, and distributor cap for wear or damage causing misfires
- Perform a compression test to assess cylinder health and detect valve or piston ring issues
- Examine cooling system for leaks, radiator blockages, or failing thermostat causing overheating
- Scan for vacuum leaks around intake manifold and hoses which can cause rough running and hesitation

Fixes:
- Replace worn valve cover gaskets and camshaft seals to stop oil leaks
- Renew ignition components such as spark plugs, wires, and distributor cap to restore proper firing
- Repair or rebuild engine components if compression test reveals valve or piston ring damage
- Flush cooling system, replace thermostat, and repair any leaks to maintain proper engine temperature
- Replace cracked or brittle vacuum hoses and ensure intake manifold seals are intact

Prevention:
- Regularly change engine oil and use high-quality oil to protect seals and internal components
- Follow scheduled maintenance for ignition system parts to prevent misfires and rough running
- Monitor coolant levels and condition, flushing the cooling system as recommended to avoid overheating
- Inspect and replace aging gaskets and seals proactively to prevent oil leaks
- Use fuel additives or high-octane fuel if recommended to keep combustion chambers clean and efficient

Maintaining the M28.47 engine in the Porsche 928 GT with these practical steps will ensure reliability and performance over time.
