Chris,
 
    C= ertainly hope the front bearing is not the cu= lprit but check with Lynn Hanover about
the possibilty of pu= lling front stationary gear without disassembling engine...........I think<= /SPAN>
it is possible as lo= ng as engine is not rotated before reassembly...........

Subject: [FlyRotary] Oil Pressure Again

I hesitate asking about this again, but I am too close to possibly fly= ing to drop the ball too much now.  I have a drop in oil pressure agai= n.  It has dropped from the high 60's or so to between 20 psi to 40 psi (2= 0 to 30 at lower RPM and only up to around 40+ as I increase power).
 
My first thought was that it was the front o-ring and silicone ring in= the front cover. So, I pulled the front pan and replaced it.  I also = was able to check the front pressure port and the oil pump chain/key/washer= etc and all was good.
 
I am about to have to pull the engine to check the bottom of the engin= e for the oil pick up and rear port (after checking the hoses, but I w= ould thinking a blockage, = depending on where it is, would increase pressure).  One of the disadv= antages of the Conversion Concepts mount is that I pretty much have to pull= the engine to check the bottom end.
 
My question is, other than the mentioned items, what else could cause = this sort of drop.  I have hooked up a mechanical pressure gage (instead of the RWS EM2).  My concern = is that it may be the front bearing as it was the only part I recall being = closer to being out of spec.  I hate the idea of having to tear down t= he engine again to replace this part especially<= A rel=3Dnofollow> since the engine is running all but perfectly and I w= as doing squawks preparing for my DAR inspection before this issue cre= pt up.
 
Also, even though I can't think of a way, is there any way to replace = the front stationary gear/= bearing without cracking the engine...just had to ask as I am not really li= king the idea of cracking open the engine again, even though I am getting a= bit too good at it....but apparently not well enough to make it actually work right.
 
As opposed to mucking= around with red hearings and wild goose chases, I figured I would just ask= again.  And yes, I have been reviewing the archives already.
 
TIA
 
Thanks
