You can buy a fairly inexpensive oil pressure gauge and install the sender in minutes and get a real reading. My first mechanic left out the plunger in the deep oil pressure relief valve and it gave me on and off oil light for about a year until the engine blew up. ----- Original Message ----- From: ATX BUS To: TCB TCB Sent: Tuesday, January 13, 2009 1:00 PM Subject: [tcb] oil pressure I need some suggestions for chasing a potential oil pressure issue. Over the weekend when I started my bus I noticed the oil pressure light did not go off. I verified that there was enough oil, restarted and the same thing happened. So I replaced the oil pressure switch and the light remains on. Any helpful suggestions on trouble shooting this situation are appreciated.
