Rear main seal leaks can start at just 60,000 to 80,000 miles.

Can a starter motor leak oil?
Oil Soak: Your vehicle's starter is typically located near the bottom of the engine leaving it vulnerable to soaking from leaks. When the starter becomes oil-soaked it will shorten its remaining life. It is important to have the leak corrected and the starter replaced before it begins to malfunction.
Can a bad alternator cause oil leak?
When the alternator seal is faulty, there is inevitably an oil leak. Oil leakage is a very severe problem as it affects the health of the engine and, eventually, its output. Even when the leakage is small, it should be treated immediately.
How do you diagnose where an oil leak is coming from?
Check your oil level by inspecting the dipstick (it often has a red or orange plastic tab on it, under the hood). If you have low oil and you're pretty sure you're seeing engine oil drips on your driveway (Remember: look for amber fluid that's slippery and smells like chemicals), then a leak is likely.
Where do most oil leaks come from?
The vast majority of leaks are due to degraded engine gaskets, oil pan leaks, oil seals or bad connections. Crawl under the car and check the oil pan seals. While you're there also check the oil pan drain plug. Next check the timing cover seal and the valve cover gaskets.
How much do oil leaks cost to repair?
Depending on the type of vehicle you have, the engine that is in it and the location of the oil leak, repair costs can range from as little as $150 to as much as $1200. The good news is there is often another solution to repair your engine oil leak.
Can I spray WD40 on alternator?
You wouldn't want to clean the alternator with WD40, as it would weaken the winding insulation. ... Again, spraying WD40 directly to the alternator may ruin it, as the liquid may get to spots where it shouldn't get to and cause harm.
What happens if oil gets into your alternator?
If you spill oil into an alternator yes you can cause it to fail it has electronic parts and diodes inside of it if you can contaminate it with oil you can foul the contact points and cause the alternator to fail. It can also eat up the plastic and cause the internal regulator to snap loose.

When your car starts having electrical problems, it's a sign you need an alternator replacement. Considering the price of a new alternator as well as labor, you should expect to spend anywhere between $500 and $1,000 to get a new one for your vehicle.
Where are the most likely places for an oil leak?
Engine oil leaks occur most often at the valve cover and oil pan gaskets, timing chain cover and the front and rear crankshaft seals. As an engine ages, heat can cause cork gaskets to harden and shrink. Heat can also cause rubber (neoprene) gaskets and seals to harden and lose elasticity.
Can you drive with an oil leak?
Operating a vehicle that is low on oil could seriously damage the engine. For these reasons, it's best to immediately stop driving your vehicle if it is leaking oil. Contact a professional mechanic as soon as possible to repair the oil leak and prevent further damage.

Does over RPM cause oil leak?
The higher the RPMS (Revolutions per minute) the faster the engine is spinning and the higher the oil pressure gets in the engine, thus if an engine is burning oil due to a worn out rings or worn out seals for example.
Is it the alternator or starter?
The alternator converts mechanical energy into electrical energy allowing the car to charge the battery while you are driving. The starter works in a different way converting electrical energy of the auto into mechanical energy.
Is my starter bad or my battery?
When you attempt to start the vehicle, is there a clicking sound, but it won't turn over? That may be a good sign. If a jump gets the car running, but won't turn over again once it's shut off, a dead battery is likely the cause.
