You'll need to find out from where in order to fix it. Get the engine steam cleaned and afterwards the source of the leak will be clearer.

If there are multiple leaks then you probably have a faulty or gunged up crankcase ventilation valve (PCV).

Engine is making oil


An engine does not make oil, but it can spill the oil that should be inside. You could have an oil leak, which means that oil will be leaking from either the front or the rear oil seal. The front oil seal is just behind the crank pulley, the one that drives the fan / alternator belt. If oil is leaking from there, suspect the front seal.
If you have oil leaking from the bell housing, that the the bell shaped metal thingy between the engine and the gearbox. you can suspect the rear oil seal.
If you inspect the engine and see oil leaking from the oil pan under the engine, you have a leaking pan gasket. This can usually be solved by tightening the pan bolts, a whole lot of bolts underneath the engine.
Finally, and this is probably the worst, if you see oil around the breather pipe that goes from the valve cover on top of the engine to the gas intake system, you have leaking compression, that means either the valve stem seals are leaking or the compression rings are finished, and you will have to have the engine overhauled, or at the very least have the cylinder head overhauled.
If the rings are suspect, you will also have excessive smoke out of the exhaust when you drive, especially when you accelerate. Check the exhaust for signs of wet oil.

Hi i have a 1994 dodge caravan it is leaking oil can this be fix im worry that we would have to save money for a van for my kids thanks


The Chrysler minivan products all had leaking problems. I have had 5 or 6 different Dodge or Plymouth minivans from 88 to 99. How bad is it. The most common thing is Valve cover leaks. Front and rear seals in the engine leak as well as the oil pan gasket. If its leaking a little bit at a time open the hood and look at the front and rear of the engine. Do you see grease and oil that has gone down the sides of the engine? Do you see a lot of grease on the engine with some clean streaks going through it. You may be able to see where its leaking from. If you know someone that knows what their doing have them change the leaky gasket/s. If not you can probably have it repaired for less than buying another van unless other things are seriously wrong with the van.
Hope this helps... Dale

Oil leak under driver side front


First thing i would do is degrease the whole engine, with oil leaks there hard to detect when the engine is very dirty, after you clean the engine and its free of all oil take it for a short drive when you get back home inspect the whole engine on the driver side and see where the fresh oil is coming from remember oil leaks downward and blows rearward when your driving so a leak on the valve cover in the front of the engine could eventually look like an oil pan leak after its been leaking for awhile if you still cant detect where the oil is coming from go to an autoparts store and ask them for detection dye, its a dye that you add to you engine oil and its used to detect leaks use a black light and then you can be very sure where the oil is coming from.

clean your engine and look very carefully where the oil leak really come from, the cause why this leak happen, the engine was shutdown while the engine temperature is hot. usually the leak will come from the turbo. the engine must be idle for 3-5min before shutting off.
