Oil Pressure Port

[BrianJ]

I have a TO-20 with no oil pressure. Trying to troubleshoot the problem and suspect the oil galley is plugged. Can the oil pressure port on the side of the block be removed? Is it threaded or held in place some other way? I want to make sure the galley is open by blowing air through it.

Thank you!

There is just a brass pipe thread fitting that connects the line from the pressure gauge to the sde of the block. The best way to remove it is to get a spare male fitting to screw into the hole after you remove the fitting that attaches to the tubing attached to the gauge.
