Hi gang:
I'm working my way to first engine start and have been turning the engine over with the starter and was not getting oil pressure or flow.
I have a O-320 with a Superior cold air sump that I assembled about 4 years ago. Reading through the archives here told me about a oil plug that needed to be removed when using the Superior pump. I could not remember doing this and was really starting to doubt myself.
Also read about pulling a vacuum on the oil pressure sending port to help prime the pump. I went to the hanger early this morning to try that trick, but was fully expecting to pull the sump off and look for that plug.
Much to my relief the vacuum trick worked, I started to see oil coming out and when I used the starter again pressure started to build. The vacuum was enough to prime the pump and away she went.
It now shows 50 psi when rolling over on the starter.
When my prop arrives next week I'll be ready for first engine start! I'm a happy camper now.
The wisdom on this forum is invaluable, Terry
