Oil pan studs or bolts?

I don't think the studs are backing out, but if they are looser once again I may pull out a few and add Loctite.

I've noticed that pattern with oil pan, transmission pan and valve cover gaskets - I assume the gaskets are compressing and losing their elastic compressibility under engine heat. In this day and age you would think they would have some miracle polymer that would not do this.

Oh, there's some nasty industrial / aerospace stuff out there that hasn't quite met all requirements for consumer use. Some are amazing and some are just plain over the top! Like... once you seal it, forget it unless you want to use hard core methods to take it apart.

Look at the 4th post on page one of this thread. BTW, I used red loctite on all the studs.

Why red and not blue? That would seem to create a big issue if you ever needed to remove 20 studs under the car.

I think you're still compressing the gasket and RTV, I'd stop tightening.

loctite grade is besides the point (the studs came out with a little extra torque). The point here was the constant loosening of the nuts and the only way I fixed it was to replace the stud set up from Canton with ARP Bolts.

Just my experience.

You could probably use a marker to confirm if they are backing out.
If they are, then perhaps a bit of Loctite as you suggested.
