Oil pressure fitting clearance?

[N941WR]

I'm curious about the clearance between the 45 degree restrictor fitting on the accessory case and the engine mount.

My O-290-D2 uses a conical mount and should be about the same case as an O-320, except for the mounts.

I have about an 1/8" clearance between the fitting in the engine mount and my fear is that the fitting will be knocked off as the engine moves around.

How close is your fitting?

I have sent these pictures off to Vans to see what they think. It might be that the engine in a conical mount sits closer to those tubes than an dynocoal engine.

Bill,
this is a problem with alot of installations, The best fix is to drill and tap a hole on the aft side of the acc. case. and plug the original. I you look at new lycomings you'll see they relocated the port to the aft side of that oil passage. You can then use a straight fitting.
