Chris, Didn't you recently do some kind of rebuild and have the oil pressure come up after the repair? What did you do and how long did the pressure stay up before it dropped again? What did you find wrong the first time?

I have both the RWS sensor and the Dynon. It seems to be having trouble getting in the mid 20 psi range. I have a busy week so I think I am about to order new oil pump and O-ring and spacer Hopefully it will arrive about the time my time frees up I figure it can't hurt and that will pretty much make everything in the engine new except the rotors and e-shaft.

I am jumping to the conclusion it is that pesky front cover O-ring. I know I was meticulous with installing it last time. While it may be something else, I doubt it. I had the pressure valve fall into the pan a couple of years ago and it is now safety wired in. Perhaps it is the oil pump but it seems so simple and not prone to failure. >> >> So, to make this more than a vent, as I know mostly how to address this....contrary to the evidence that I am having to screw with it again, is there any words of wisdom y'all would care to share. Since I will at least have the front cover off (should be able to do do with engine on the plane) would this be a good time to replace the oil pump. It has not been replaced in the past do it is many years old with an unknown number of miles. Is there a "better" oil pump out there than the turbo version offered by Mazdatrix that I should ponder? >> >> I may have the oil ring and plastic retaining ring already if I can find them. Just gotta find the time to crack into it. Then to continue my turbo diagnosis. Great power without intercooler (even though I found no restriction, but it is a super cheap intercooler from eBay) and blow off valve or even N/A. Obvious limited breathing with the cheap intercooler and blow off valve >> >> TIA. >> >> Chris Barber >> Houston >> >> Sent from my iPhone 4 >> -- >> Homepage: http://www.flyrotary.com/ >> Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html > > -- > Homepage: http://www.flyrotary.com/ > Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html
