Mayhaps
If the Old Lifters were "fed" a diet of 5W40 FULLY synthetic
(From a"New" State)
[Say "Redline's" 5W40] they wouldn't "Clacketh",now.

In ANY case... Do Not Run ANYTHING through the Sump
EXCEPT the Correct Viscosity DIESEL rated Motor Oil.

NO: WD40
NO: Marvel Mystery Oil
NO: Mineral Spirits
NO EXCEPTIONS !
