when my car sits at idle, it leaks nothing but as soon as i rev it or drive it, it likes to just pour out oil. its coming from the very front of the motor so i though i would replace my front main seal. replaced it as well as my cam seals yesturday but still leaks like crazy. i took off the front timing cover upper/lower and started the car. when i rev it, i can see oil pouring out from between the bottom of the head and the top of the back timing cover. i just put this motor together and was driving it for a while without major problems until recently. what could this be?
