I’m confused again….The shaft appears grooved below the water pump impeller…So, the sleeve would not have to be disturbed when doing water pump maintenance… The groove above the impeller is where the seal for the aluminum impeller housing rides…This seal has nothing to do with keeping oil inside the case, it helps seal up the water pump….I’m not that concerned about the groove above the impeller…So, perhaps you could just install the sleeve below the impeller to take care of the groove where the oil seal rides…
But, once again, my vote is for a better driveshaft…You are spending alot of time and money on this project, may as well go all the way and make it right…
