If one is not carefull when replacing the gaskets on the blowers they will crimp. Loosen cover just enough to take a look. This will be a messy process, set the blower up so you can let the gear lube drain over night, clean up the area around the gasket seal really good, reinstall the gasket with a smig of rtv and slightly snug, but don't tighten. wait 24 hours and torque to spec's
