Gauge issues/heating issues/high oil pressure
Okay, so to start i'm driving a 94 ford ranger 4x4 xlt 4.0. The issue started a while back with the oil pressure reading high then followed by the temperature climbing rather high staying at that temp for a short time, perhaps a minute or two tops, then it drops back to to normal. So talked to a few people, came up with a quick check solution other then the obvious checking of fluids. Had the filter swapped to make sure it wasn't clogged. Once done truck continued to do the same thing. While waiting though i talked with the shop manager about other possible causes, he gave me the idea of checking the Sending Unit for the Temperature Gauge. Apparently, when the unit starts to go bad it messes with the gauges. I checked it all out turns out that wasn't the problem. What I did discover though was this particular part that I had previously thought may have been the problem, may in fact be the problem. Now here's the brick wall that I've come to. I own the repair manual for the truck and cannot find anything that tells me what it is, nor have the numerous part stores I've been too as well. I'm lead to believe its an Oil Pressure Unit, but everything I've seen tells me that it show be on the passenger side of the vehicle. Well this little part is driver side. Can anyone help me out? Seems the store's cant and I'd like to fix this issue. I have two photos but I cant guarantee they'll help, any kind of feed back is very appreciated.
