I have ( I think) an old rod if you want it.
Are you sure you properly replaced the o-rings under the rocker arm stands for the oil leak?
I would fix the engine/clutch noise before spending $$ on the Roper Plate .
The replacement of all the relays will be a good idea as preventive maintenance. These can be purchased at an automotive parts store . Take one with you so they can look through a buyer's guide for a match. Some of these relays have more terminals than others , so check all of them in the fuse / relay panel .
