To recap, I had lower oil pressure than I felt comfortable with even though=
the engine was running strong. I tried to check/replace the pesky front h=
ousing o-ring while in the plane to bad resutls.
Apparantly what happened is that when I tried to replace the o-ring, the ro=
ller bearing slipped off its little lip and got a little chewed up in the m=
inute or two I ran the engine to see if oil pressure was up. Since pressur=
e was not up, I decided to remove then engine and have a closer look. When=
I did I found the bearing. So, I tore down most the engine and had a clos=
er look. While apart I also replaced the front main bearing which was ques=
tionable and as y'all may recall, it was bad.
Upon closer inspection I determined that my front housing was the later typ=
e that also needed the little plastic (silicone) o-ring support. No, not r=
eally sure how I missed this as I was aware of the change but only had the =
o-ring installed
I have not been out at the hangar much this month (too many single women re=
lying on me ;-)), however, I was able to flush the parts/system, replace th=
e front bearing, both front roller bearings and o-ring and support ring (ev=
erything else looks really good) got it all together...again.... added fres=
h oil and filter and last night cranked her up. She fired right up (gee, a=
fter several times doing this I am starting to get everything lined up and =
timed pretty well).
Low and behold the oil pressure is the highest I have ever seen on my engin=
e. That makes sense since I was apparently forcing oil past the unsupporte=
d o-ring. I did not go WOT, but only to about 5000 rpm, I think, and I wa=
s getting to the high 80's PSI on a mechanical gage. Finally.
Ok, tomorrow starts my weekend so now hopefully to button everything back u=
p properly and maybe actually make some progress.
