I was changing the oil in my 97 F150 and made a dumb mistake. In my rush, I did not check the old oil filter to make sure the gasket came off with it. I installed the new filter (motorcraft), filled it with 6 qts of oil, checked the level and fired it up. I picked up my tools, took about 2 minutes, climbed in the truck and noticed the oil pressure gauge had not moved and the oil light was on. I immediately killed the truck. Never once did I hear any knocking or valve train noise while it was running but the gauge registered no oil pressure. I traced the problem to the oil filter housing where the old oil ring was still present, causing oil to blow out between the filter and housing. Would this cause me to not have oil pressure or for just the gauge to tell me I didn't? Does it get its reading from the oil filter housing? The motor is a 4.6 just in case. Thanks guys.
