On the A and B series engines the Oil Suction Screen goes into sump from the bottom of the engine and is captured by p/n 61381 suction tube. Have any of you amazing mechs out there had any problems with this brazed assembly, specifically, it sucking air at the gasket where it mounts inside the accessory case? I have an engine that suddenly developed a problem at a normal oil change (also cleaned screen). Won't make over 25 psi oil pressure. It also has an AirWolf remote filter kit which has been trouble free for years. No metal in oil and Airwolf guys said I might have a bad spin-on filter, but tried another to no avail. First, I did put a calibrated gage and hose on it to verify its not a gage problem. Anyone have any ideas before I remove the Sump? Hoping someone has seen this.
