Do you have a good relationship with any mechanics? The dye is available separately, so all you need are the glasses and a good light as mentioned. You might just buy the dye and borrow the glasses and a good light. A good light would be the most expensive part of the proposition. Heck, a shop may do it for/with you for not much more than the cost of the components themselves which might be the way to go if this were to be your only need for the light and glasses.
The dye works really good if the area around the car is not too bright and if you have a good UV light. You don't even need to clean the suspected area before testing.
Master, again and still

Don't overlook the bakc of the intake, vlave covers, cylinder heads, cam and oil galley plugs  I brake clean the area including in side the BH until it is dry as the mojave in august. Start the motor, let it idle till warm and check. Next start again runt at ~ 250 RPM for 3-5 minutes, check again. Next a short road test at lower speeds. Finally a highway run if needed. try some uphill downhill runs if possible. keep us posted.

"runt at 250 RPM ?? I think you meant 2,500 RPM (we knew that  )

I have cleaned the back of the block with brake clean a couple of times looking for the leak. It's not coming from the intake, valve covers, oil galley plugs or cam plug. I also do not see any oil below the rear main seal or on the sides of the rear mail retainer. They only place I see it is at the very back of the oil pan. It doesn't leak while idling only when driving. In fact, if I baby it it leaks very little, if I get on it a couple of time going around the block it leaks bad. I've taken the pan/windage tray off and the oil pain gaskets looked great when I took them off. I replaced them and reinstalled everything. Still leaks

I bought a cheap light and glasses combo off Amazon and saw the ac dye easily. Not sure if that shows better than one for motor oil, but cheap worked for me.
I want my fair share

Might check that PCV valve, too.

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.

One has to isolate the source FIRST Had a customer years ago that cased a leak on a fresh resto before brig it in. 1st question was: are you sure the galley plugs are tight and sealed. Said he did them himself. After 5 pan gaskets 2 rear mains 1oil pan by him, We did the pan gasket, put rear main in, and put the original pan back on. No change. I had thoroughly de-oiled the BH'sng etc. I put a small piece of wadded up paper towel on a set of mechanical fingers and snuck it up into the BH'sng avoiding the rear main etc. It came back down with fresh oil. Remover the trans, bh, and flywheel while he watched. Upper R galley plug was finger tight  . I have more stories but you have to diagnose before going for the "FIX" You're comment about it leaks worse with higher RPM? make sure you're not building excess crankcase pressure Keep us posted

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.

I have used a fiber optic camera between the block and flywheel and can see no oil up there. I've tried the toilet paper on long tweezers as well. The rear main and oil galley plugs are dry. I taped a diaper (paper towel) to the back the engine and the leak was where the rear main retainer met the the oil pan.
