I think that's just how it is...? Here's that corner on an old motor in my garage. The gasket follows the pan/block on all the other corners, but much less so in that one corner.

I keep preaching tis method because it works, and it simplifies the process. I've installed more pan gaskets than most, and I HATE leaks. You'll be pleased with this:
The typical issues leading to leaks are gasket/seal bulging on the side rails, and corners not being sealed by the rubber gasket. What to do??
- Clean all old sealant from the corners of the BLOCK, OIL PUMP, AND oil pan. A small wire brush works pretty well.
- Oil the gasket with your hands. Make sure it's wet all around; all sides top and bottom, front and back. Not dripping, just wet with motor oil.
- Put a bead of Loctite 574 along the oil pump seam at the front of the side rails. It should be at same level as the pan rail.
- Lay the gasket on the rails, put pan in place and start all bolts.
- Use the factory method for torqueing the bolts, both sequence and torque.
- After the last pass, go back and ensure all bolts are at final torque. Center bolts will probably be loose.
- Last, worry about something else, your pan will not leak.

I did a quick search for Locktite 574 and Amazon offered up with two styles - liquid and paste. Which one would you recommend?

That's a good question Jay -
I have the 574 that I used for the balance shaft sealing process. Not sure if that is considered past or liquid. I remember it was orange.

@michaelmount123
The instructions you posted - was that with the engine on a stand? Anything different doing it underneath the car? Obviously it is a royal pain! Wish it would have worked completely dry the first time!

Loctite 574 will be the correct sealant, whether it's listed as a paste or liquid.
I (almost) always installed the pan on a stand, but installation under the car is the same process.
BTW, the oiled gasket will not bulge, and the oil allows the gasket to squirm up into the corners to seal them up without any sealant. Do clean the corners of old sealant; both on the block and on the pan.

One more clarification...
Put a bead of Loctite 574 along the oil pump seam at the front of the side rails. It should be at same level as the pan rail.
Do you mean in the area I shaded red? Not on the semicircular part...?

No, not the area in red. I mean the seam on the block where the oil pump meets the block. This is on the BLOCK, not the pan. Just a small bead of 574 on top of that seam.
Does this clarify?
