Need help finding some sensors etc

[pro2am]

I have an 89 with 2.3. It's new to me and I've been trying to change out some of the sensors and the PCV but can't seem to find them on the engine.

Can someone describe where to find the oil pressure sensor, the water temp sensor, and the PCV?

Some of the stuff on this engine seems really hard to get to...like spark plugs, so I imagine some of the above is hidden behind something?

Thanks in advance.

oil pressure sensor is directly below and behind the #4 intake runner, single wire sensor, isn't too hard to reach the wire but changing it would be a PIA

coolant temp sensor for the gage is just above and behind the oil filter near the #3 intake runner, the one for the computer is near the #2 fuel injector on the intake manifold

the PCV valve is directly behind the intake manifold joint if I remember right, look for two hoses of different size joining together, the adapter is the PCV valve

Thanks! I have to work it again this weekend so I'll be sure to get those taken care of.
