Why you put 25PSI air in lower plug? The impeller change kit comes with all new gaskets, wear plate, impeller, etc. Maybe you forced air past the drive shaft seal? Good Luck!

You need to keep going in the other thread instead of starting a new one.
25 is too much pressure, and you need to pull the water pump to see the oil seals and they have nothing to do with the water pump kit
