After investigating, I've come to the conclusion that the torque specs
changed from Gen 3 to Gen 4. Both the Toyota and the Haynes manuals
confirm this. They increased the torque and I believe the rubber seals
are thicker on the later design. Toyota probably did this due to the
sealing problems with this engine.
Any Toyota techs out there that can confirm this?
