What could cause oil to leak out all at once?

Hi, I have a 1994 Chrysler Concord 3.5 that leaks oil.


I'm confused because it doesn't appear to be leaking a little at a time but all at once.


I will check it every other day and it will be fine and then one day I'll go out there and it will be almost empty as if it just gushed out all at once.


What could cause this?


I've never heard of this happening before but it seems to be the case right now with this car.


Thanks for any advice you may have to offer.What could cause oil to leak out all at once?
fast leaks are usually do to 1 of 3 problems or a combination of them all.





Front crankshaft/camshaft seal , pan gaskets , or rear main crankshaft seal .





I have seen valve covers leak really bad also.





Mainly it's one of the 3 .





Very commonly it's the pan gasket and/or rear main crankshaft seal.





Do not run a thicker oil (or fix-a-leak like LUCAS oil stabilizer). it will starve the thousands of an inch oil gap clearances in the various parts of the engine.





This is a common ';friendly mechanic'; suggestion to people with engine knocking/tapping sounds , leaks , or oil lights coming on.





Repair the vehicle properly and save yourself from other costly repairs . What could cause oil to leak out all at once?
It sounds like you are overlooking something like maybe a dip stick that is not going all the way in. Is there a large puddle under it on the days it is almost empty? Does it really need 4 or 5 quarts of oil on those days? Is your neighbor sneaking over at night and draining your oil occasionally? I have known that to happen in all sorts of permutations. I would at least start checking it every day at the same time and location. Also, check your PCV system. Pressure in the crankcase can force oil up the dipstick until the level in the oil pan drops below the bottom of the stick at which point it begins to read correctly.
during the car warm if there is any leaking seals it will cause it to come out all at once..there might be a leaking rear main seal or a leaking pan gaskt leaking head gaskets or a leaking bolt...you have to try to find where the leak is coming from...there might just be a leak and there is something that clogs it up and then gets tossed around and starts leaking...
well that depends on when you are checking it is it warm or cold was the engine just ran? did you try to add oil to the car when this happens then wait and check again to see if it is even higher than what it was the other day
It could be a hole in your oil filter or a bad gasket between it and your engine block.
you better check the drain plug. if it,s leaking that much all at 1 time then the plug might not be there.
typical, did you forget to put the oil filler cap back on?
