The compressor takes a loooooong time to fill up with air...it is about 7 years old...it also sounds like it is leaking air as its filling up but the sound stops when the motor shuts off...its spitting out a little bit of oil also from around a gasket on the motor

You need to fill the air conditioning system with Freon.
It's the clutch on the air compressor engaging and disengaging because there's not enough pressure in the system.
It's rather easy to do, all auto parts stores have refill kits, in a better store someone can probably go out to your vehicle and spend 5 minutes to show you how to use it.
It's drastically cheaper than taking it to a place to have it done.
With a vehicle only 2 years old though, you shouldn't be having to do this already, unless it's a high mileage car. If you have to keep refilling it more than once a year, you'll have to take it to someone to find the leak.
Thanks for choosing FixYa and welcome. It sounds like you may need to add freon to the unit. Your A/C line should have a service port on it, looks like a bicycle tire valve, just bigger. The pipes are aluminum, so they are easy to pin point. You can buy the freon at Autozone, Advanced, or even Walmart. You may have a leak causing the freon to leak, but since it is 11 years old, it may just need filled.
If air leaks when motor is off, fault most likely in-tank check valve. Follow discharge air line from pump to tank. Brass/steel valve at tank is the check valve. Remove hose to valve and check for leak. Replace as needed. If air is leaking while motor is running fault could be reed valves in head. Faulty reed valves in head, or torn head gaskets will cause very hot discharge air and tank will most likely never fill to shut off (or take a very long time to fill)
The start valve gives your motor a running start before the motor begins to load as the pressure increases from an empty tank. The motor strain is more profound when there is pressure in the tank. If you plug the valve, the motor will instantly encounter a heavy load because it has to force air into a partially filled tank. This extra load without the valve will shorten the life of the capacitors and motor windings. There could be two problems with your unit that can revealed by test. What actually closes the valve is a certain volume of air produced by the compressor. If the compressor is not pumping to full efficiency or there are leaks in the discharge hose the valve will not close. Or the valve is faulty. With an empty tank, plug the valve and run compressor and test airline for leaks with soapy water. If no leaks, empty tank of air and restart compressor and take note of the amount of time it takes to fill the tanks to shut off. If it takes an unusually long time to fill, then the compressor probably has valve problems causing low air volume. If the compressor fills to shut off in a short time frame as compared to a similar model then replace the valve. Leaking valves in the head will also cause the pump and discharge tube to run very hot. Parts are available at www.toolpartsdirect.com Good luck with your repair.
There is a one way checkvalve installed on the tank that prevents air from returning to the pump. Follow the discharge hose from the pump to the tank. You will see a brass valve that has a 1/4 inch hose attached that leads to the pressure switch where you will find the unloader valve. Check if the unloader valve is leaking and continues to leak when you turn off the pump. If the valve at the pressure switch is leaking ~ then the check valve at the tank is the source of the leak and needs to be cleaned to replaced. Some low volume compressors will never fill if the tank check valve is bad. Check this first and email me for more information. Good Luck
Most compressors with the problem that you are having suffer from leaking valves. As in a gasoline engine, leaking valves will lower efficiency. Valves in a compressor are in the form of reeds that seal against valve plate. Leaking reed valves or gaskets will increase the discharge air temperture. Inspect these parts with a magnifying lense. Look for evidense of wear or leaks. Also look for signs of air leaking from one cylinder to the other thru gaskets. Replace valve plate as necessary. Simple test, as your compressor is filling, check the intake for strong suction; as it neers the 92 psi mark suction will probably deminish if you have leaking valves. If suction remains strong at 92psi then you have a leak at the discharge side. Check with soapy water on all parts. Good luck
