Hey
Guys;
Last winter I experienced the low oil pressure caused by a blown oil ring
in the front cover. I then removed the front cover gasket, sanded down the oil
ring and reinstalled as per the instruction in the rebuild video (why the heck
didn't I do this in the first place?). Worked great, with no more oil pressure
problems. However the damage was already done. Tracy had this same problem some
years ago (why didn't I pay closer attention?), but suffered no damage from it,
so I really wasn't too worried about it, however it seems that the turbo places
great enough loads on the engine that it did do damage to my main rotor
bearings. It seems to have wiped most of the babbet off as can be seen in the
attached pic. The stationary gear bearings don't seem to have suffered at
all.
