Oil leak solved, bad underdrive pulley!

Update by Per Schroeder to the Nissan Sentra SE-R project car
Jun 24, 2005

Last Friday, we noticed a new and substantial oil leak from the front crank pulley seal. This is the same seal that we replaced when we installed the GoFastBits underdrive pulley. Closer examination showed that the pulley actually had a groove dug into it. This, coupled with a prematurely worn seal caused our oil leak. We reinstalled the stock pulley and a new stock sized serpentine belt.
