Okay,
I am losing oil pressure on my mini truck. 145k on the odometer. Is this common on these engines or should I be looking elsewhere?

It is not common for a 22re to lose pressure, it is common for a toyota oil pressure sending unit to go bad. If I remember correctly I had to tap the block to fit an autometer plumbing pipe thread, it was super close but not samed thread pitch.
I will check the sending unit but this engine is making more noise than usual. This truck was not maintained very well and I knew it when I bought it. Doesn't burn oil, it leaks it out the valve cover gasket. It is acting like the oil pump is bad. Thanks

oh crapWell I found the problem. After pulling the oil pan I found chunks of plastic in the oil pan. The Timing chain guides had shredded off and were laying in the oil pan. They would get sucked up against the siphon screen and block the oil flow causing the drop in oil pressure. So if your rig has good oil pressure at start up then drops slowly as it runs this may be your problem. Just FYI.
