I've been thinking about a mishap I had a while back with the oil pressure in my truck.
1989 4.0
I had installed new rod bearings to regain some oil pressure while setting aside money for a complete rebuild. I had to do something as the truck was my daily driver. Everything went fine. Fresh oil and a NAPA Gold filter. oil pressure was definitly better. Drove home (60 miles) and around this small city and to work a couple of times. No problems, good oil pressure.
A few days later, I started it up in the morning and drove around the corner and heard something hissing. Leaving the truck idling at a stop sign, I got out expecting to find a tire going down. It was coming from the engine compartment though. I popped the hood and there was oil everywhere. It was squirting out at the filter/adapter interface. I shut it down immediately. I saw a trail of oil down the block. I followed it and saw it started back at my house. I pushed the truck back home (slightly down hill luckily). I found the oil filter blown up like a balloon. The oil pressure sender was also destroyed by this.
I figured the oil filter had failed. Is this the likely scenario? Seems the oil would have gone to the filter and been stopped right there. With nowhere to go, it blew the seal due to the extreme pressure. For this to be right, I think the oil must enter the filter through the holes around the center mounting hole and then into the engine through the center mounting hole.
I replaced the oil and filter and everything was good from then on.
Any thoughts on this odd occurrance?
BTW, the NAPA store where I bought everything did offer replace the filter (to that, I said no thanks) and the oil (I did take that). I've been using Mobil1 filters since then.
