Turbo check valve

[geoffb]

Was just at the hangar and noticed a small oil puddle on the right side.  Oil is coming out of the exhaust pipe.

Last flew 5 days ago, a 3-hour leg.  Didn’t notice oil over the weekend.  No significant oil loss.  No boost issues in flight at 14.5.  Check valve?  Which one?

Probably the return check valve. Take it apart and check the spring that closes the flapper. It is probably broken. No real problem except it makes a mess. Tomgo has some for cheap(ish).

Thanks to both of you.  Rajay has the same Dukes valve?

I don't believe you have a Rajay turbocharger.  Maybe the same check valve can be used, but I would look at the IPC or Continental TSIO-360-MB documentation before proceeding.

I believe they are all the same. They are built under a mil spec. There are a few manufacturers building the mil spec parts. That makes them standard parts for those who qualify for that.

I've got the IPC, don't worry.  Just trying to gather experience from the group before I tear into this thing.  Guys like Rich and Lance and several other longer-term K model owners have generously saved me a lot of time.

and correct, the -MB has a Garrett, not a Rajay.
