ok so i decided to remove the sleeve for the syncro seal off the
pulley. I purchased a 2wd seal for $8... put it all back together
tonight, ran the van for a bit... all looks good..
I have also decided that i can't be bothered to check the end play or
blow by because i do not plan on using a wbx'r much longer.. most
likely going with a subie 2.5
thanks for all your help and replies!
