Is there any way to CHECK, other than remove the front cover? You say this effects temps too. My temps do seem a mite higher than before. John Hi John; I couldn't think of any way and I spent more time thinking about than it actually took to do the job. However I would call Bruce first, as I recall that my pressures were even lower than yours. This shouldn't affect temps as well, but temps do affect pressures, so this is why I suggested reporting temps along with pressures & RPM to Bruce. I just tried to find info on how low my pressures were, however due to my high altitude induced hard drive crash on my laptop last summer, I've lost that data. I can't seem to find it in the FlyRotary archives, but I did find another somewhat related post of mine (pasted below) on what I found when I tore the engine down after I detonated it. 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. I don't mean to scare you with this, but as you are also turbocharged, I thought you should at least have the info. However I would still call Bruce before doing anything, since I'm certain he would have already done the mod.
