Engine Oil Leak...need help...

hey everyone..i need all of your opinions as to where to look?? i know im leaking oil cuz last month i changed oil and i filled it a little bit past the top marker on the dipstick..yesterday i checked it again and its already in the halfmark of the 2 dots in the dipstick..where could the leak possibly be...i know its not on the oil filter or the oil drain bolt cuz i already checked it...what are my suspects??gasket?

its coming from under the car.. cuz the top(valve cover)doesnt have any oil leaks that i can see..my car has 150,000miles on it..

Sometimes very hard to find as you have alredy seen..do you have any little puddles under you car..put down newspaper if you have a garage and check for leaks...also does your car smoke when you start it up or if you gun the motor?
 
Check those out and report to the forum...

check for oil spots on the ground, its possible you are burning oil

Its gotta go someplace.
 
Out the tailpipe.  Smell it, because it can burn some without making noticable smoke.
 
Headgasket.  Look for oily scum in the radiator.  Not just in the overflow tank.
 
If it leaks OUT you should be able to find a puddle on the garage floor & go from there.
 

when i start it it doesnt smoke.. yeah i have little puddles under the car and i have put newspaper under it but i couldnt really pinpoint where it is coming from because some of the oil drips into the buttom of the tranny and it spreads there..at first i thought it was the tranny becuz of that but its not...

*edit* i took some pic...seems its coming from the one i pointed..

so anybody know what the cause is? gasket??

Try and follow where the bulk of the oil comes from. Make sure the drain plug and filter are tight. The last place i had my oil changed they didnt screw the drain plug all the way so i was leaking a considerable amount of oil.
