Oil screen hole misalignment (5 hole acces. case)

Posted for Russ:

Hi Bruce - Russ Farris here. Could you post this picture in the Hangar forum for me? My IA is overhauling my O-300A and noticed this offset between the hole for the low pressure oil screen and the hole in the oil sump. It's the five bolt style. The short body oil screen that came off the engine fits fine, but he tried a long body screen for a three bolt sump by mistake and was concerned when it didn't go all the way in. Another concern would be would the F & M oil filter adapter fit properly. I'm hoping someone can confirm all the five bolt cover/sumps look like this - I'm sure Tom Downey would know.

Thanks Russ Farris
