I sent my car with my Mechanic Friday afternoon to fix brakes, change fan and computer. My mechanic said car would be done and returned Saturday morning.
Saturday afternoon, he calls to tell me that I need a new battery and alternator. He said he drove it made several stops and Saturday morning took it to pick up parts. Upon returning to my car it would not start. He removed the battery took it home to charge and found battery and alternator needed to be replaced. Alternator had oil leakage in it. He replaced battery and alternator made several stops again and dropped my car off Sunday E
It would be difficult to say exactly how much oil it would take to cause the alternator to fail. However, oil leaking on the alternator due to leaking valve cover gaskets can cause it to fail. It seems as if the technician who is servicing your vehicle may not have performed a courtesy inspection to check for other potential issues prior to starting the other repairs you had requested. I would recommend having the alternator replaced if it has oil leaking on it as well as resolving the valve cover gasket leak to prevent it from happening again. You may try to use a different mechanic who is more upfront and honest in the first place. Consider YourMechanic as services such as this can be completed from your home or office.
How to Identify and Fix Common car Problems ?

Oil penetration can damage the alternator within a very short time and lead to failure.
On many vehicles the VTEC assembly is located directly above the dipstick and alternator. If the VTEC gasket has failed this is the source of your oil leak and alternator failure.
Some alternators have a vacuum pump attached to it that enables the brake servo to work. The pump is lubricated with oil from the engine. The oil seals that separate the pump from the alternator can fail and will result in an oil leak.
It is recommended to have a dedicated grease gun for alternator bearing re-lubrication only. Never mix lubricant types. As per the Installation, Service & Maintenance manuals, it is vital that the grease, grease gun, grease nozzle and relubrication nipple are free from abrasive materials and other contaminants.
Your car`s alternator may fail for various reasons: Age and use-related wear is often the reason behind a dying alternator. Engine oil or power steering fluid leaking onto the car alternator can lead to its failure. Prolonged idling while using multiple electrical accessories can prematurely wear the alternator.
To check alternator diode leakage, connect the multimeter in series with the alternator output terminal when the car is not running. Leakage current should be a couple of milliamps at most. More often, it will be on the order of 0.5 milliamps. Use care when disconnecting the alternator output wire.
While it might seem easy to ignore a few drops of oil on your driveway, it`s always a bad idea. Left unaddressed, a small oil leak can grow into a larger, much more expensive repair. Plus, if the leak worsens while a vehicle is in operation, it can cause the engine to seize.
Q: Can I still drive with an oil leak? A: It`s always advisable not to drive if your vehicle has an oil leak, but short distance drives, less than 10 miles, are not as risky when it comes to lowering your oil levels to a dangerous point.
Using WD-40 to repel water from spark plugs, distributors, alternators, and batteries is a good way to prevent corrosion and keep moisture away. You can also use it to ease the removal of spark plugs, especially if there is any rust or corrosion.
Prior to rinsing your motor you will want to cover your alternator with a microfiber towel or plastic bag, you do not want any water getting into your alternator that may potentially harm it.
Krytox™ lubricants are commonly used to extend service life of chassis components and power train components including: Anti-lock brakes. Alternators.
A special water-based degreaser and demineralized hot water is used for cleaning. Once the cleaning has been completed, the alternator will be tightly covered and will be dried by a portable heating and drying system.
One of the most common problems you`re likely to experience with an alternator is a failure in the bearings. There are needle bearings in the alternator that allow the rotor to freely spin inside the housing, and those bearings can break down over time as a result of exposure to heat and dirt.
While a car alternator usually lasts the car`s lifetime, it can deteriorate and malfunction under certain circumstances. Factors such as normal wear and tear, damaged parts, exposure to water or heat, and overuse can cause your alternator to stop working.
While you can technically still drive with a bad alternator, it is not advised. This is especially true in newer vehicle models. This is because there is more electricity involved compared to an older model.
Look for an ideal alternator reading of around 12.6. Start the car, and look for a reading of between 14.2 and 14.7. A reading of over 14.7 means the battery is being overcharged, while a reading under 14.2 means the alternator is undercharging the battery.
Use WD-40 and spray the entire greasy engine compartment with it. Remove the grease and grime with water and rinse it off. Depending on how dirty your engine is, you can also use a small brush to remove the grease for the hard-to-reach parts.
Also, you can look at the bottom of the engine to see if there are any oil spots or drips. If you notice a significant drop (more than ¼ of the dipstick) in a week`s time, check carefully for new leaks or other problems.
Engine Gasket This is the number one area where oil leaks can develop and, we won`t lie, it`s devastating. There is a long seal between your cylinder heads, oil pan, and the engine block, and if this seal breaks, oil can leak into the cylinders and damage your engine.
Leaking Oil Filter The filter is one of the most common causes of an oil leak. Ideally, the oil filter should be replaced with every oil change. If you change your oil at home, you may forget this important step or the new filter may not be installed properly.
The first sign of an oil leak isn`t necessarily a major problem. Once you determine you have adequate oil in your engine, it is possible to continue driving in the short term. It`s always best to treat an oil leak as soon as possible, however, to ensure a larger oil leak doesn`t catch you off guard.
To keep the alternator from overheating, make sure it`s clean and free of any dirt, grease or other debris on its exterior. Anything that traps the heat inside the alternator will kill it in short order. Check the condition of the electrical connections on the alternator and at the battery.
Alternator repair kits are usually less than $30, depending on which components you need to fix. Again, you need the proper tools and a little know-how, but if you`re able to find the right kit and know what you`re doing, you can rebuild an alternator for a fraction of the cost of even a remanufactured unit.
Most alternators will last between 80,000 and 150,000 miles — or about seven years. However, your driving habits and the area where you live could wear it out prematurely.
