Default Final Torque Value for 944/968 oil pan Bolts

Hello all. I asked this question in my other thread about the oil pan DIY, but I also had other questions that were answered while this one got overlooked. I decided to start a new thread for this question only.

I have seen 3 different torque values for the "final" torque setting of the oil pan gasket for the 944/968. The Clarks Garage instructions state 6 ft-lbs (8.16 Nm), most others say 7 ft-lbs (9.52 Nm), and at least one source says 7.5 ft.-lbs. (10.2 Nm). Do you guys know which one is the correct value for the final torque setting? Thanks again for all the help

According to the booklet published by Porsche, 7 ft lbs.

The correct value is 10 Nm. Lb/ft values are a conversion and rounded. An accurate conversion would be 7.375621492943471 lb/ft but unlikely to find a wrench with that setting Porsche rounds it to 7 which suggests a bit under 10 Nm is okay if a metric scale wrench is not available.

It's important to go back and re-torque each 6mm bolt after the final torque is reached. You'll find that at least the center bolts in the sequence will be loose, so ensuring they are actually at 10Nm, 7 lb/ft, 84 lb/in. is important.

That makes sense now. I actually replaced the gasket a month or so ago but I hadn't done the correct procedure on the RTV silicone at the corners and there was a leak at the front in the curved semi-circular area. When I went back to take out the oil pan again I noticed that the center bolts were a bit loose, just like you said. The interesting thing was that there was no leak by the looser bolts, the only leak was at the front.

There was a 3 week gap between the time I tightened the bolts and when I went back to take out the oil pan and noticed the side bolts were loose. So how long after the oil pan installation should I go back and re-torque to 10Nm?......a week, two weeks?

Immediately upon installation. Snug up all your bolts during the first go around, then double check torque spec a second time once everything has been tightened down.

Yes, I understand that. I did each of the steps several times until all the bolts were at the correct torques. The final 10Nm step took around 5 rounds of tightening until all bolts were (and stayed at) 10 Nm. Even so, after 3 weeks when I took the pan out again 3 of the side bolts were looser than the rest.
