Engine Repairs & Overhauls in Polokwane
Engine Repairs & Overhauls at Our Polokwane Workshop
Engine work is where an accurate diagnosis matters most, because the difference between the right repair and the wrong one is measured in tens of thousands of rands. We carry out compression and leak-down testing, pressure testing and oil analysis before an engine is opened, so the diagnosis is factual.
Symptoms We See
- A rattle for a few seconds on cold start-up, often a timing chain or tensioner
- Overheating, coolant loss or a sweet smell after a drive
- Blue smoke on start-up or under load, or white smoke that will not clear
- Oil on the driveway or the smell of oil burning off the exhaust
- Loss of power, a whistling turbo or excessive exhaust smoke under boost
- Knocking or tapping that increases with engine speed
What the Work Involves
- Timing chain, guide and tensioner replacement
- Cylinder head removal, skimming and head gasket replacement
- Oil leak tracing and rocker cover, sump and seal replacement
- Cooling system, water pump, thermostat and radiator repair
- Turbocharger diagnosis, replacement and actuator calibration
- Full engine overhaul and reassembly to specification
How We Diagnose It
We confirm mechanical condition before dismantling: compression and leak-down tests show whether the problem is rings, valves or a gasket; a cooling system pressure test finds an external leak or a combustion leak into the coolant; a dye test locates the true source of an oil leak, which is frequently higher up the engine than where the oil appears. Only then do we quote, and the quote states exactly what is included.
Mercedes-Benz Applications
Certain Mercedes-Benz engines have documented weak points we see regularly, including timing chain wear on some four-cylinder petrol units, balance shaft and idler gear wear on early M272 and M273 V6 and V8 engines, and oil cooler seal and rocker cover leaks. Knowing which engine you have tells us where to look first and shortens the diagnostic time you pay for.
This work is also carried out on BMW, Audi, Volkswagen and Porsche vehicles. If your car is a Mercedes-Benz, the Mercedes-Benz Specialists page explains our model-specific capability in more detail.

Engine Repairs — Frequently Asked Questions
It depends on the vehicle's overall condition, the cause of the failure and part availability. We quote both routes honestly where both are realistic, and we say which one we would choose.
Take it seriously. On chain-driven engines it usually means chain stretch or a tensioner that is not holding oil pressure. Attended to early it is a manageable repair; ignored it can result in a jumped chain and bent valves.
Yes, and quickly, because continuing to drive an overheating German engine frequently turns a thermostat or water pump job into a cylinder head job.
Usually. We clean the engine down, run it with a UV dye in the oil and inspect under ultraviolet light, which shows the actual origin rather than where the oil finally drips.
