Taping and installing screws was a great way to fix the issue. Nice fix!
I have to wonder how many other motors were tagged like that over the years, and how many complaints Perkins may have received from its customers! I tought about plugging the holes but really wanted to keep the Perkins rebuild tag in place as it is part of the history of the motor. Funny thing is you have to bend way over to see it under the manifold, so when the fenders are back on the truck, you probably won't be able to see it at all.
