Get a couple cans of engine cleaner from an auto parts store. Spray the entire engine (get under it too) . wait a while then hose off engine with water. Let it dry then start the engine to see where the oil is coming from.

SOURCE: how to locate the engine oil leak does the car need to be running

Usually you won't see a leak until the car is parked. It's a good idea to put a piece of cardboard under the car after it's been driven to detect the leak or leaks. If you see any drops or puddle on the cardboard, crawl underneath the car and lookup under the engine to see where the leak is coming from. Look at the area above the puddle or dripping.

2001 Chrysler concorde has an oil leak but only when motor is running, what is the cause?


If it is engine oil leaking, it is coming from either the valve covers, the front seal at the timing cover, or the rear seal. You state that it does not leak when parked, but in most cases, the oil will continue to drip off the engine after shut off, and you will see oil spots on the ground below the car. The location should indicate where to look for the leaking area.

If the leak is not engine oil, it could be transmission fluid, power steering fluid, or even brake fluid. With the engine running, see where the fluid is puddling below the car. This will be a very good indication of where to look for the component that is leaking.

Oil leak


Pressure wash and clean the engine. Once clean observe engine closely while running to determine where oil leaks are located.

2001 ford taurus Have a constant leak oil light has been on for weeks 3 days ago car would not turn on went to auto advance to get the battery check; replace battery car still shut off, permenantly f


There are some simple kits which have a glowing fluid which can be seen with a UV ultraviolet light supplied in the kit.

You add the glowing liquid to the engine, run the motor, and inspect the drips for the leak location. Then you fix that bad part.

Now sometimes the sending units do leak. But any gasket or seal can leak just as well.

Do not run the engine with the oil light on. Check your oil level constantly. No oil=no engine.

Can not speculate on battery problem from info provided.

I know that there is an oil leak but i cannot tell exactly where.


Oil leaks can be a pain to locate so I will give you a few tricks I've picked up along the way for locating oil leaks. Start by cleaning/degreasing the area. You want to remove as much of the old residue as possible. Then you can do several things from here.

1. Purchase and oil dye additive (this additive makes the oil glow when a black light i shined on it) and run the engine for a little while then re-inspect with black light to find locations where dye is concentrated.

2. After cleaning, spray the are that you suspect the leak is coming from with a spray on type foot powder(powdre sprays on white providing an excellent contrast to trace leak). Run the engine and follow the oil trail to source of leak.

Found oil underneath but cannot see any oil dripping from the bottom of the engine? the oil filter is on tight, i checked the dip stick and the oil is full.also is ther any history of front end problems...


That series of Jimmys and Blazers are known for front wheel bearings failing. If you start hearing a load rubbing or dry grinding have them checked and when you replace one do them both. With the oil problem, could it be transmission fluid? You might have a leaky transmission cooler line.

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.

Oil leak


The oil pressure switch could be leaking. It is common on the 2.8 V6's. Clean the area off w/ engine degreaser, dry it off, then let run for a few minutes to verify the location of the leak.
