As Ed and I have both suggested, please try priming through the opening as shown on Ed's post. That would be by far the easiest way to get your prime back. A first-timer may have trouble finding the big 13/16 cap/bolt to remove, but it's there and not hard to access once you locate it and figure out whether to reach it from the right or left side. Use a strong flashlight to peek in to find it. I do mine from the left side with a big box-end 13/16 wrench. I use a squirt oil can with a plastic tube 8" or so long. Once I take out that 13/16 plug, I use my fingers to guide the tube into the hole an inch or so; you can feel when it goes in. Then a few squirts (maybe five or six) of heavy oil is all you should need. I've used 30-wt. oil as well as 80w-90 gear oil. It has NEVER failed to bring my oil pressure back up within a few seconds of cranking once I put the big plug back in. I doubt whether your heavy oil could cause your pressure loss; the heavy oil would actually be less likely to leak down to let you lose prime, although sometimes cold weather can do unexpected things. If squirting oil into the hole doesn't restore your prime, you almost surely have a problem elsewhere in the system. Keep us informed.
