I could tell you many long faced stories.
110 K engine spun #7 main.
Plastic, Yes I SAID plastic oil cooling jets! They jumped out of the block.
No OP to the rear mains.

Mine is a One Ton and it is used like a truck.
It never leaves the yard to go get the mail or groceries.
It is DRW has all instruments and is monitored. EGT, FP, Boost. ETC
To just do a rotor swap, get ready for a hellish day, they are INBOARD.
And yes I know all the tricks in removing them.
