Went to fly today with a friend in their SuperCub.
On startup, zero oil pressure. We checked the usual suspects and didn't find anything. Suspected a bad gauge but disconnected the OP line to see if oil was flowing. Nope. Blew out hoses and the oil cooler... nope. etc.
How likely is an oil pump failure on a O-320-A1A? What are some possible failure modes and symptoms (aside from zero oil pressure)?
Thanks,
Glenn
