hmmm, I've never had an oil temp sensor. I've only had an oil pressure unit, on the back of the block behind the distributor, and a block/coolant temp located on either head, one of my cars have even had one in each head. my 2cents :)
the temp sensor is on the driver side of the engine block next to the exhaust manifold.
Could be the temp sensor..there could also be an oil pressure sensor at the top, back,or the block.
Most of them are as simple and unbolting the old one and bolting in the new one.
There is usually at least one or two pipe plugs in the intake manifold that can be removed.

No.
Yes their the same block....
no
next to the thermostat housing.
It is in front of the starter on my van.1990 350
the temp of the intake manifold is controlled by the temp of the water in the block.
195 to 210 degrees is NORMAL operating temperature.
