Changed oil and tried checking torque (reference +3's May 7 post):
Can't get torque wrench on these
Over 35 ft-lbs. Tried 50 and bolt started to turn so would assume its OK (have no past experience to know how much torque increases with a torque/angle tightening sequence).
Over 59.
Around 50 - bolt seemed to turn slightly but car wasn't on a lift and I couldn't get any more torque.
Good thing is that after a year and 23k miles everything is spotless - not a drop of oil anywhere!
