It is probably the o-ring in your oil pump. I have the exact problem in my Cavalier. it is a little expensive to fix and I believe you practically have to pull the motor to replace it. Just keep oil in it and you might want to wash down the motor compartment area to cut down the oil spray areas. Don't use a cleaner that will make it too clean because with a motor that oil you may cause more leaks. Sometimes with an old motor you need the build-up around certain sealed parts to fill gaps because it is an older motor. I had that problem with my Old mustang may she RIP, i used a detergent oil because I was told to and it started leaking 3 - 4 qts. of oil weekly and didn't before I used the detergent oil.

SOURCE: chevy cavalier 1997 2.2 coolant leak

Thankyou for the reply post. I found it was the water pump and just because it appears that the weap hole is at the top of the water pump it is in fact there is one at the bottom. But with further inspection and replaceing the water pump I was informed that I have a head gasket leak at the front of the engine. It is at this time small. And will require $$$$$$$$ ( $ 800.00 to $ 1300.00 est. ) to repair, I paid only $700.00 for the car and to this day have put in $1100.00 to it. But I love the car! But if can survive till the taxes come next year, I can do it. Baby it and don't drive it much, God willing it will be ok.

SOURCE: 2000 chevy cavalier having coolant leak. Found a

That hose is the drain hose for the air conditioner evaporator. If it is leaking coolant, there's a good chance that your heater core is leaking, as it is in the same 'box' that the air conditioner evaporator is in. You'll need to replace the heater core.

SOURCE: My 2001 chevy cavalier has a oil leak and I can't

You can buy a florescent dye to add to the oil and a light to make the dye really shine.
Clean the engine with "brake clean" from a spray can at the oil leak areas ....then run the engine.
Check for the start location of the leak.
Start with a short run time ....... then longer run time if necessary until the leak(s) show.
With or with out the dye ......this brake cleaning method should help locate the leak(s).

Oil leak locations could be...in order of the most common on your car are........valve cover gasket,oil filter,oil pressure sending unit,drain plug,oil pan gasket,crank pickup sensor,rear seal.

SOURCE: 98 Chevy cavalier overheating

That is really quick, like you are getting no water flow at all. Make sure that a radiator hose is not collapsing enough to stop the flow. If possible on that model, take off the radiator cap and shine a light to see if the water passages in the radiator are clogged up with rust or sediment. If this started after the new thermostat was installed, make sure it was not put in backwards.

Chevy 2005 cavalier low coolant light keeps coming on and the coolant reservoit tank is empty after only 200 miles. what is causing this?

  1. Check the hoses and clamps going from the reservoir to the radiator and from the radiator to the engine. Make sure they are flexible and in good condition.
  2. Check the reservoir and radiator for leaks.
  3. Replace any parts they may be failing. If no leaks are found proceed to next step.
  4. Check engine oil. If oil has coolant in it you may have a blown head gasket or crack in the head or engine block. Another sign of a coolant leak into the cylinders is white smoke coming from the exhaust after the engine is warmed up.

1999 chevy cavalier oils like milk in coffee, antifreeze leaked bad last winter, summer only drove 4-6 miles a week checked every time I went to store, used 1/3-1/2 gallon antifreeze, now getting cold out...

you're getting water in to your oil that's why its milky. could be a bad head gasket ,cracked head, or a cracked block, usually one of the last 2. better get it to a mechanic, if its the block it would probably be cheaper to replace the engine, it takes less time and most places charge 75-100 dollars an hour

Motor oil spewing onto the engine. my car is a 1996 chevy cavalier and well maintaned. it has a radiator leak also. could the antifreeze be mixing with engine oil

Unfortunately, this sounds like you have a bad head gasket. The motor oil is most likely mixing with the antifreeze as well. This also explains the antifreeze leak.

I wish I had better news for you! :(

1996 cavalier bad oil leak when running

Overfilled is not good but it would have to be very high to cause leak,There are numerous places in rear of engine that could be leaking.could be leaking from rear of intake,the oilpump drive o ring,but most likly leaking from rear main seal that seals at the rear of the crankshaft and the transmission will need to come out to access this seal. you will need to have the oil leak diagnosed to locate the exact spot.

Oil leaks

First of all, which engine does your cavalier have? Some GM engines around that time had problems with the intake manifold gasket leaking oil where the manifold bolted to the top of the engine block, but if I remember correctly, it was in the 3.1 liter V-6 engines. If your car has a 4 cylinder engine, I am not aware of any inherent oil leak problems.
BTW, if your oil light has been on for 2 weeks, without your adding any oil, you probably have more serious problems than just an oil leak by now. Maybe not a solution, but it's a place to start.

Water leaking from a freeze plug and water in the oil pan in a 283 small block chevy engine

If you have a bad or leaky freeze plug, also known as soft plugs, it needs to be replaced. Your brass plugs are the best, and in some hard to get to places there are rubber plugs that can be adjusted to fix the problem. But if you have oil in the oil pan, assuming no one put water in the engine. You probably overheated the engine enough to acquire a cracked head gasket. Normaly that's the problem, could be a cracked head also, but more than likely a gasket. If you decide to remove the heads and replace the gaskets, good idea to have the heads resurfaced.
