Crud In Bell Housing
Recently pulled the engine out of my 08 Impreza 2.5i manual. Ant the entire
interior of the bell housing is black with oil and dirt, a lot of it. I'm going to
clean it and remove the flywheel and clutch and clean everything with break
cleaner. I've already bought a new rear main seal (crank seal) and replace that
with the hopes of fixing any leaks. Should I be worried all of this is coming
from the transmission - how can one tell if it's coming from the transmission?
Thanks
