[DML] Re: front main seal leak



Did you put some sealant under the sleeve, and did you oil the pulley 
shaft before inserting the pulley onto the crank and into the seal? 
Does that seal have a tension spring inside it? It's a slightly 
tighter fit with the sleeve and if it's difficult to get in you can 
knock the small spring (if that seal used one) off the sleeve. 

Check the crankcase pressure by running the engine with the oil 
filler cap removed, but if it still leaks my guess is that you either 
nicked the seal during installation or dislodged the tension spring 
in the seal. If that happened, when you remove the pulley again 
you'll see the spring wrapped around the crank - you may need a 
mirror to see it.
