I would bet a bad impeller, myself. You’re more likely to find a bad impeller in one of the old TN’s than any of the later motors, because they’re not as simple to replace. The star impellers on the TN, is a huge improvement over the earlier TD waterpump.
The tell tales on those motors are not really a correct form, anyhow, because on these, the water squirts out there, before it goes into the engine. You really don’t want any water loss, before the water goes through the engine and these do just that.
A correct tell tale should actually show some of the discharged water, so you’ll know it’s went through the block. On a lot of the other motors, a correct tell tale is piped off of the top of the block, not the bottom.
