Seal blown

Oil filter leaking or not seated or sealed?

Yes, there's another correct answer...Maxst2 hhoooraayyy for Max

Here is another answer for my own question...
** Oil Prssure Sending Unit (switch) leaking, this is one of the main causes of the Puddle Of Oil under Car Thingy.....

And 6th Gen was close on the 4th answer...it is that your engine oil seals are leaking...something else to watch out for is when you pull a plug and its getting a load of oil on it...This is caused by a leaking $2.19 cent seal

Later..WheelBrokerAng[8D]

could also be a stipped oil pan..although i doubt youd have a huge puddle unless u leave it sit for a while..

I'm throwing in my vote for the oil pan gasket...all 3 accords i've owned have had bad gaskets..

good info.
