Note on oil plate stud/nut tightening, etc.: Pinky Tight is correct. Just snug plus a little bit. You just know how small the stud is and how weak the Al is. Go easy. Using Modern tech with billet machined plate and "O" ring seal -- very nice. Surprised Galat did not recommend drilling out the case threads and taping with Helicoils, which, if I were building an engine -- I definitely am not -- I would do at every opportunity presented, this one in particular. another area would be the alternator stand to engine joint, so that one could remove the studs there and use bolts instead thus facilitating R&R of alternator. But, hey, that's just me.
The Bentley manual specs 5 ft. lbs. for the 6mm oil strainer plate nuts, Kelly, and as you said, that's snug plus a little bit. I've always found that when choked up on the ratchet or wrench it's just right. I've also noticed that when the 6mm cap nuts (the cap nuts, along with the copper washers sealed the studs) were overtightened, along with the strainer plate deforming around the holes, the threads in the cap nuts would start to strip. I think the cap nuts would bottom on the studs and they'd be destroyed before the studs. I'm guesssing VW made the cap nuts soft intentionally, as they are easier to replace than the studs or the threads in the case.
Yeah, inserting the strainer stud holes would prevent damage, but that's expensive to have done, and as I said earlier, replacing the 5 studs just wound into the case with the appropriate length bolts wound through from the inside is the easy/cheap fix (the 6th stud already has a nut holding it place as it's the pick up anchor). That way you'll never pull the threads out of the magnesium case. And I've mentioned this before but I'll say it again- tapping the case with 7mm threads with the larger hardware will make sure a sump never comes loose.
And next engine I do will get inserts for the 2 rear generator/alternator studs so they can be bolted in from the top. The 2 front studs will remain with the front holes being slotted so the stand just slides back once the 2 rear bolts are pulled. Al
