I know your troubles.. I had the same problem... a 2.0 gsr.. and the sleeves started to drop.or it blows a hole in the side of an exhaust port. it gets frustrating when you dump 1000's on dollars into a motor and then something major is messed up... sounds like you have a good fix though, good luck.. I gave up on the full "race motor" too many headaches...

again good luck
