I have decided to redo my main crank seal as it has been leaking and making a mess of things. The oil seaps past the seal and gets oil on the belt and pullies and gives me inconsistant ET and traps at the track. So before i begin racing again this season i have decided to redo this seal clean all the pullies and replace the belt once again even though i put a new one on in october.

I was surprised when i saw the seal and now know why changing to the 178 pulley might have caused this. Just bumping this thing off center would alow oil to leak out while running and i must have bumped the seal or damaged it during install.

I'm curious as to how difficult it was to pull the old seal out for others who have done this and any tips that could be given before I undertake this and reinstall the new one.
