How long ago was your S/C installed? The 2AZ-FE motors are rock solid with only one known issue. This was a small batch of motors with some mis-sized main bearings. The TRD S/C have had numerous problems on the TRD side of it. Interested in how much oil actually leaked past the impeller shaft seal. It would take a bad leak to drop your oil level quickly. If this is the case, it would be a quality control issue with the Vortech S/C and not the TRD parts.
Mine is dry and soon as I can figure out how to get the impeller off the shaft, I will check the shaft seal. So far, my problem has been a cracked end bearing.
