2006 Mustang 4.0 V6 150,000 miles - oil pressure warning

Customer Question

2006 Mustang 4.0 V6 150,000 miles - oil pressure warning light comes on, engine valve train noise appears. Remove engine, replace timing chains & guides (Ford factory parts) , reassemble and reinstall engine. Runs good, valves quiet, 0 oil pressure at idle, 15 lbs @ 2000 RPM. Drop pan, replace oil pump, check for debris in pickup tube. Reinstall oil pump, oil pressure still the same. Before removing and disassembling engine, is a there a galley plug or some other problem I can look for?
Thank You, Bruce

Hello my name is***** most common place to lose oil pressure is from the crankshaft bearing clearance being excessive. Another way we find out where the leak is , is remove the oil sender and with the engine out and valve covers and oil pan off. We use shop air pressure through the oil sender port and then listen for massive air leakage. Could be bearings or upper end cam journal wear or a lash adjuster out of the hole in the cylinder head. Just apply air and pinpoint the air leak when the engine is on a engine stand. Anymore questions just ask Thanks Scott
