I've used foot powder spray in the areas of most likely leaks.
When I drive it around "the block" ( 3 miles ) it leaves a 4" puddle of oil on the shop floor in 10 minutes. It's REALLY leaking.
Coat both sides of a new pan gasket with Loctite 515 Gasket Eliminator (or Loctite 518 GE) and put that out of the way. I've used Loctite 515 Gasket Eliminator for decades and
never a bad result.
I used the Right Stuff which most folks like. I may have to give the loctite a try. I have a windage tray so I have two gaskets to worry about.
The Right Stuff is great! Just be careful where you use it. It bonds so well that you can damage the part that you are sealing should you ever need to take it back apart. Personally, I wouldn't use it on the pan and tray. I think you would have to damage/destroy the pan rail and tray to get it apart.
I don't have any experience with the Loctite product. Sounds interesting.
