Missile finally back!

[74657]

We flew my plane home today from the repair shop.  Finally.  About a 2 weeks back it went up for the test flight and the fresh engine had low oil pressure.  The engine guy took the engine back, tore it down and re-assembled it.  It was re-installed this week.  During the test flight the mechanic who did the airframe repairs and my mechanic noticed that the oil pressure dropped to around 60 psi during flight.  It showed 80 lbs. when cool and as the oil temp rose to 220F the pressure dropped and stabilized.  On final when power was pulled the pressure dropped to 10-15 lbs!  Idle pressure showed 25 while hot.  I called the engine guy and flew the plane to his airport about 30 miles away.  He hopped in and spent an hour and a half in the plane and felt that everything was fine.  He said the air was hot and contributed to the high oil temps as well as the engine being new.  His feeling was that it there are no issues with it.

All we need to do is some minor re-painting and it is set.  At this point, I could give a rip if it has some primer on it..... I want to go flying.

Glad the Saga is over.  I hope you enjoy many years of trouble free missile flying!

10-15 PSI sounds awful low for any engine.  From the TCDS, the IO-550-A  oil pressure limits are:

2-4-6 side - - Normal 30-60 p.s.i.g.

- Idle 10 p.s.i.g.

Maximum (cold oil) 100 p.s.i.g.

Whats the warranty on the engine?  If he is satisfied with it now then why did he tear it down and reassemble it? Did he use new bearings and rings, etc?

I hope it works out for you.
