Dear Jim;
I've never heard of that one. Hard to say where it came from etc.
Sounds like low oil pressure, or to thin an oil could have been used. The distance (4,600) is not long or the speed (3,300) to high. I doubt that your trip/operation was the cause.
How many times was the oil changed during the 'break in' period?? What about after/during the trip?? Were you using multi-grade oil??
Did the 'rebuilder' make the suggestion?
Check with Mike G. He may have some info on this subject.
Good luck.
