Where is my leak coming from?

Clean the engine off really thoroughly. Then monitor it closely looking for the leak as you drive over the next day or so. Oil usually leaks from the valve cover gasket or front main seal on that side of the engine.

Th engine have oil all around. Its dificult to tell whit out see it. But wash th engine in a car was. Then let it dry, start th car and u will see where is this leak starting from

Hello,

This means there is leak somewhere. One or more worn out oil seal is the cause of the problem.

The engine has a lot oil seals which prevents oil from leaking.

First, you need to look under the car, to get the exact spot of the leakage.

Use a touch light so that you can see clearly. Clean under the engine that is stained with oil with a rag and observe where the oil is coming out from. So, when there is a fresh leak, you can get the exact spot. If there is no more oil in the car, put some.....

You said there is a card board under your engine; remove the card board to see clearing where the leaking is coming from.

Also, you asked if the engine has to come out; yes, the engine will come out. Though it might not be the whole engine. Part or the whole engine will come out, depending on where the leak is coming from. The leak is inside the engine, this is why is has to come out.

When you get the spot, you will have to bring out that part of the engine. Get a oil seal kit and do the replacement. This is no going to a easy task because it require a lot of man power. So you can call a friend to assist you.

But if this task is difficult for you, you might call a mechanic........

Below is what the oil seal and it replacement kit looks like;

The oil you described is called blow back, which means the oil leaking is blowing back on the bottom side of van,, Those vans are known for computor problems, Which means they need re flashed once they start like dash lites wont come on or cooling fan wont come on and van over heats,or wipers ,radio wont come on than all of a sudden they come on,,I just got rid of a nice looking 98 had same problems.Also the main bearing on yours is leaking oil, I wont buy that van.You do what you want but Dodge,cryseler,are cheap made vehecles, I just answered a 2000 van that had the reflash problem here on fixya.So look around.

Valve Covers, Head Gaskets, Oil Pan Seal and a number of other spots. You'll need to clean the motor with Gunk Engine cleaner and then look for the largest build ups of oil and crud to get a better idea where it is.

Hi!
That's a lot of oil loss, And its not normal or maybe when you put the oil in maybe it needed 2 Qt then you put one and it still needed one or you might be leaking oil. Did you notice any leaks under your car when you park home ? Check for leaks because that's a lot of oil and the car wont burn that much from work to home, Is there any smoke coming from the tail pipe ?

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.

There are several places it could be coming from.
The primary one is the oil pan. This would be the pan directly under the engine. It has the oil pan drain plug in it. If you are unfamiliar with the underside of automobiles you need to be sure you are not looking at the transmission oil pan. The first pan will be the oil pan. If you are mechanically inclined and have basic tools you can try and tighten up the oil pan bolts around the circumference of the pan.
Normally if the leak is from the pan it will appear wet all around the bottom. However the leak could also be from the rear main seal at the back of the engine. This can leak down to the pan and appear to come from the oil pan. Most of the time a leak from this will be in one spot of the pan, leaving the front section dry.
The other place is from the valve covers. You can check this by look under the hood at the side of the engine. If it's wet along the sides, that might be where it's from.

The only way you are going to know for sure is to get under it and look for yourself or take it somewhere to have looked at. You should have time to do this as long as you maintain the oil level in the engine.
I hope this helps.

Add about 2.5-quarts of new engine oil to the engine.
Remove the passenger-side wheel, and support the car on jack-stands.
Start the engine and look for oil leak.
Chances are leaks are coming from failed oil-pan gasket or the drain-plug.
The head-cover gasket could be failing as well..

It could be the Oil pressure sensor is bad and leaking oil, There know to go bad and will leak worst when driving as the oil pressure goes up.
Good luck and hope this helps.
