Parts and contaminants · 3 min readRemoving carbon deposits from engine valvesIntake valves on direct-injection petrol engines and exhaust valves on every engine carry hard carbon on the tulip and stem. How to clean valves once the head is off, keep each valve with its guide, and tell a cleaned valve that can be refaced from one that is scrap.
Parts and contaminants · 3 min readRemoving heavy grease and sludge from engine partsCrankshafts, connecting rods, sumps, timing covers and gearbox cases come in coated in oil, sludge and road grime. The hot soak, the ultrasonic cycle and the skimmer that let one bath degrease a week of engine rebuilds instead of a day.
Parts and contaminants · 4 min readCleaning engine blocks after machiningBoring, honing and decking leave chips, abrasive grit and honing oil in bores, galleries and blind holes, and one grain in an oil gallery can wipe a new bearing. How rebuilders and remanufacturers clean a machined block, with the tank sizes and loads that fit car and truck blocks.
Parts and contaminants · 3 min readUltrasonic cleaning of turbocharger componentsCoked oil in the bearing housing, soot in the turbine housing, sticking vanes in a variable-geometry ring, oil film on the compressor side. How a turbo rebuilder strips and cleans each part, which metals need which bath, and what gets replaced rather than cleaned.
Parts and contaminants · 3 min readUltrasonic cleaning of cylinder heads for automotive repairCarbon in the chambers and ports, oil sludge under the cam covers, scale in the water jacket, gasket remains on the deck. How a head is stripped, which bath suits aluminium and which suits cast iron, and where cleaning sits between crack testing and valve-seat work.
Parts and contaminants · 4 min readCleaning EGR valves in an ultrasonic tankSoot and oil mist bake into a hard cake in the EGR valve and its passages. How to remove the bulk, protect the actuator, which liquid and temperature break the rest, and how to tell a cleaned valve from one that needs replacing.
Parts and contaminants · 4 min readRemoving carbon deposits and baked-on oilCarbon on pistons, valves, injectors, turbo housings and EGR valves is oil that has been cooked onto the metal. It needs the hot end of the bath, the strong end of the chemistry, 28 kHz, and time. What works, what does not, and how to avoid damaging aluminium in the process.
