Chris I do not know the size of this o-ring you & others have had a problem with but  I  have been servicing automobiles for 30 years,  automatic trans & computer controlled sys. as specialty, we use, in some places Teflon sealing rings in various sizes  ( 1/16" X 3/8" to 1.0" around,  1/8" X similar diam. ) they are somewhat soft yet very strong, they have some crush capability but I am sure they would not blow out with a high pressure situation. Take an o-ring to any trans shop & ask to match it to a Teflon ring.  Check with Lynn.  David.

Subject: [FlyRotary] Pesky front cover O-ring

Just pulled my front cover and low and behold that damned front cover O-ring was fricken GONE. The retaining ring was in place but no sign of the o-ring. Is it ok to pretty much glue this damn thing in some how????  Lynn suggested a metal solution but that is not in my skill set. I have halamar and used it last time. Yes, I did instal the ring.
So, since I bought it I will be installing the new oil pump. Heck, the old one is over 20 years old.  If any of y'all has a remedy for this damned thing slipping out you will have my complete attention.
Oh, I am sending a picture or how I am making the front cover area easier to get to :-)
