M18 low oil pressure
Hi, low oil pressure light stays on in my 1862 with Kohler M18 after start up. Oil level is correct. After riding for 20 min the light went off. Next start up - the same problem, but it took longer for the light to go off and the engine started to slow dow due to overheating. I am using SAE30 and NAPA's gold filter (cross-referenced to the Kohler's original).
I took the closure plate off, inspected bypass valve, oil pump, blowed the air through oil passages - everything looks good. Ordered the new bypass valve just in case. I will also intall OEM oil filter and try using 10W30.
Any ideas what could be wrong? Could it be the non-OEM filter?
