My van has an oil leak which seems to drip all the way from the front to the back of the van any one know why?

I got out of work and notice my van was leaking alot of oil I looked under the chasis and notice it was leaking in several places. The leaks came from under the oil pan it seems and all through the back of the chassis near the back wheel its a big leak because I just put 2 quarts and its almost gone...is it normal to have a big leak like that out of nowere and leaking in several places?My van has an oil leak which seems to drip all the way from the front to the back of the van any one know why?
It's not probably leaking in several places but it is probably leaking backwards on the car as you drive. If it is a bad enough leak it will look like it is leaking from several places. It sounds very serious and needs to be checked.My van has an oil leak which seems to drip all the way from the front to the back of the van any one know why?
Not common to start leaking in several different places. What it sounds like to me is a large leak that gets blown all over your undercarriage by the wind while you drive. This is very common. Generally speaking you can usually find leaks this big at the rear main seal. Without knowing anything about your vehicle I would say that is the best starting place to look. What you can do is wash the entire undercarriage with a garden hose so all the oil is gone. Top off the engine, and then let the van idle. After a few minutes get underneath it (while it's running) and see if you can pinpoint the leak.





P.S. Rear main seal is where the engine and transmission come together.





Good Luck.
If this leak suddenly started and has not been previously leaking oil it could be the oil pressure switch. They had a seal between the plastic and metal halves and will start leaking and leaking significantly. Also the oil filter can loosen if it wasn't tightened properly.

The wind and such usually blows it all over the place. You must clean it up a bit and then start it and look for the leak. some big leaks start quick and cover the whole undernieth of the car/truck. Look for other things like a loose oil filter and such also. always good to check the simple things first.
