I have 2 houseplants, one is a new log or totem pole and the other is a philodendron. When I water sometimes, I pour some down into their stem, but lately there is foul odor like wet laundry that has set for weeks. It's a bad smell, only on those 2 plants. HELP. They still look good and healthy, their shoots just stink.

It sounds like the plants may have root rot and what you smell is the roots decomposing. There is not much that can be done to help the plants, but this article may help: https://www.gardeningknowhow.com/plant-problems/disease/treating-root-rot-gardening-tips-for-housplants.htm
They over watered it and this is what caused the root rot.
