Default B20B4 oil leak need help!!!!!!!!!!!!!

i did a basic tune up changed timing belt and tensioner plugs wires cap and rotor valve cover gasket and oil pan gasket. Motor ran great but there seemed to be a small oil leak on the oil pan, so i took it off again and put another on it and the leak got alittle worse. By this time i was getn frustrated as hell so i talked to my friend who had put on alot more oilpan gaskets on than i have cause i thought it could have been something i was doing. But then it leaked even more and its only when its running and it seems to be leaking all the way around the oil pan, Need some helpfull info.

Dont have a breather my motor is basicly stock besides intake header exhaust Fuel rail with new venom injectors. i did tighten them down in sequence but u did bring up a good point that i never though the oil pan could be warped

my b20 block was leaking oil too, me and my friends swore up and down it was oil pan. We ended up redoing it 2-3 times before we found out the fitting you tap the block for a vtec head actually broke. Just wanted to throw that out there as a possible oil leak prob

if u changed the gasket then most likely it would be that the surface is warped....

it could...cuz if its not flat then the oil pan wouldnt be sitting on there flat...but most likely from my experience its the pressure buildup...mine did the same thing....or bad gasket.....

What do you do to get ride of the pressure, and if i do get ride of it i still have to change my gasket right? And would it make my valve cover leak to, like the more i drive it? How bad is it for the motor?
