Does the open end of the oil seal point towards the inside of the engine or does it point outward? I have the seal installed with the flat side pointed out...open (spring) side pointed in towards the clutch side. Is that correct? I know you are supposed to out the spring side towards the side you want to seal...but the engine has oil on both sides so I'm not sure which side it goes on. My guess is in due to pressure on the clutch side. Thanks!
