Alright guys I need some help here. Had some nice weather and decided to change the oil. I bought a NAPA 1365 oil filter put it on and it is leaking from the seal. Looking in the hand book it has a tork setting of 8 Nm. One thing I have noticed is that once the ring seats up against the motor there doesn't seem to be too much room to tighten. I don't have a tork wrench. Is that really necessary?
