Peugeot 301 Engine Blocks

The main parts of a Peugeot engine include the engine block which houses the cylinders, pistons that move up and down to create combustion, the crankshaft that converts linear motion to rotational power, the cylinder head containing valves and camshafts, and the timing belt or chain that synchronizes everything. Additional critical components include the oil pump, water pump, gaskets, sensors, and in turbocharged Peugeot THP engines, the turbocharger assembly which typically costs R15,000-R35,000 to replace in South Africa.

Common signs include unusual noises like knocking or ticking from the engine bay, visible oil or coolant leaks under your Peugeot, excessive exhaust smoke (blue indicates oil burning, white suggests coolant), loss of power especially when climbing Gauteng hills, rough idling, poor fuel economy, and dashboard warning lights. In Peugeot BlueHDi and DV6 diesel engines, hard starting and excessive black smoke can indicate injector or turbo problems requiring immediate attention to prevent expensive damage.

Pricing varies widely depending on the component and Peugeot model: timing belt kits range from R2,500-R5,500, water pumps R800-R2,800, gasket sets R1,200-R4,500, camshaft position sensors R650-R1,800, and oil pumps R1,500-R3,500. Labour costs in South African workshops typically add R800-R1,500 per hour, with major engine work on EP6 or THP engines potentially requiring 6-12 hours depending on complexity.

Timing belts on Peugeot engines require replacement every 80,000-120,000 km depending on the engine code (EP6, THP, DV6), with water pumps often replaced simultaneously. Spark plugs need changing every 30,000-60,000 km, engine oil and filters every 15,000 km or annually under South African conditions, and air filters every 20,000-30,000 km (more frequently in dusty areas). Always consult your specific Peugeot model service schedule as neglecting these intervals can lead to engine damage costing R50,000+ to repair.

Quality aftermarket engine parts from reputable brands are acceptable for many components like filters, gaskets, and sensors, often costing 20-40% less than genuine Peugeot parts while maintaining good quality. However, for critical components like timing belts, camshafts, pistons, and turbochargers, genuine or OEM-equivalent parts are strongly recommended to ensure proper fitment and reliability. Many South African Peugeot specialists stock brands like Bosch, Continental, and Gates which meet or exceed original specifications at competitive prices.
