There are a few potential causes for oil spitting out of the dipstick of your 1995 Mazda Millenia:
1. Excessive oil pressure: This can be caused by a number of factors, including a faulty oil pump, a clogged oil filter, or worn piston rings.
2. Faulty PCV valve: The PCV (positive crankcase ventilation) valve helps to regulate the pressure inside the engine crankcase. If the PCV valve is faulty, it can cause the pressure in the crankcase to build up, leading to oil being forced out of the dipstick tube.
3. Worn piston rings: Worn piston rings can allow combustion gases to leak into the crankcase, which can also cause the pressure to build up and force oil out of the dipstick tube.
4. Damaged oil pan gasket: A damaged oil pan gasket can allow oil to leak out of the bottom of the oil pan and onto the ground, which can also lead to oil being forced out of the dipstick tube.
Diagnosis and Repair
To diagnose the exact cause of the oil spitting out of the dipstick, it will be necessary to have your car inspected by a qualified mechanic. Once the cause has been determined, the necessary repairs can be performed to fix the problem and prevent further oil loss.
Some of the repairs that may be necessary to fix the oil spitting problem include:
1. Replacing the oil pump
2. Cleaning or replacing the oil filter
3. Replacing the piston rings
4. Replacing the PCV valve
5. Repairing or replacing the oil pan gasket
It is important to address the oil spitting problem as soon as possible to prevent further damage to your car's engine. If you notice that your car is spitting oil out of the dipstick, it is best to have it inspected by a qualified mechanic right away.
