Question: My Peugeot Partner Tepee 2013 had its DPF changed, and since this change, I am using 2 liters of oil every 4 or 5 hundred miles. In the morning, see if you can find any signs of oil drops on the floor after parking for the car for the night. What can be the cause?Īnswer: You can check for an internal or external leak. The smoke doesn't have a bad color and I can't hear any suspicious sound, everything seems to be perfect. Question: My car is consuming too much oil. Also, check the tailpipe for a black, sooty film. If necessary, wash the engine and transmission and see if you can find an external leak after driving the car. Question: How does a Toyota Quantum consume one pint of oil every day, but it doesn't smoke and its power is not affected?Īnswer: There's either an internal leak or external leak. If your engine has high mileage, worn-out bearings can have the same effect on the rings allowing too much oil around the bottom of the pistons this is excess oil that the oil control rings might not be able to handle well and a leak through the cylinder is possible. Usually, an internal leak will leave an oily thin film inside the tailpipe. If the cylinders and valves are not synchronized, the vacuum may pull engine oil through the valve stems and guides into the combustion chamber.Īlso, there could be an internal oil leak through the piston rings or cylinders. Operating the engine with ignition timing problems may lead to excessive oil consumption as well.Failing to change dirty engine oil will accelerate the deterioration of gaskets and seals and the wearing of pistons, piston rings, cylinders, and bearings.Hot spots will distort the cylinder and allow oil to leak into the combustion chamber, leading to high oil consumption. Operating your vehicle with an overheating engine (bad cooling system, bad cooling fan or thermostat) can create hot spots around one or more cylinders.Switching to a low-quality oil can promote carbon buildup around piston rings, leading to ring malfunction and oil leaks.Switching to a lighter weight oil than the one recommended by your car manufacturer: for example, switching from 15W-40 to 5W-30 or 10W-30.Pulling heavy loads, especially in mountainous terrain.You may want to wait for the leak to become more noticeable, or you may want to use an oil leak detection kit. Sometimes the leak is so small that you won't be able to find the source through a normal visual inspection. To inspect the rear seal, though, you would need to separate the transmission from the engine.Ĩ. If the leak is in the rear of the engine, the rear seal may be leaking. You may need to remove the timing belt cover.ħ. If the leak seems to come from the front of the engine, check the front seal for damage, or the gasket in the oil pump housing. Then, check that the oil pressure switch is not damaged or loose.Ħ. If you just replaced the filter, verify that the old filter gasket was removed. If the leak seems to come from the engine oil filter area, check that the filter is tightened properly. Aso, make sure the bolts are tightened to the correct torque, and the drain plug and gasket are still good. Inspect the condition of the oil pan gasket. Another common source of leaks is the oil pan underneath the engine.
