The oil sender unit on a 3300 engine is typically located on the engine block, near the oil filter or oil pump. It is usually threaded into the block and connected to the oil pressure gauge or warning light. To access it, you may need to remove any obstructing components depending on the specific vehicle model. Always consult the vehicle's service manual for precise location and instructions.
An oil sender unit, also known as an oil pressure sender, is a component in an engine that monitors the oil pressure and sends this information to the vehicle's oil pressure gauge or the engine control unit (ECU). It typically consists of a pressure-sensitive mechanism that generates an electrical signal proportional to the oil pressure. This allows the driver to be alerted to any potential oil pressure issues, which could indicate problems such as low oil levels or engine wear. Proper functioning of the oil sender unit is crucial for maintaining engine health and performance.

Round shape oil pressure sender on the passanger side to the right of the oil filter. Oil pressure sender sends how much psi your oil pump pushes out to the ecu.
the oil sender unit need to be replace.
top up the oil or change the oil sender unit ???
Sounds like a wiring or sender unit problem. Ground wire at sender unit, see if it stays steady. If it still jumps around, wiring/gauge problem. If it stays steady, sender unit should be replaced. Good idea to do an oil pressure test as well.
Right behind the distributor.
Look at the top of the engine at the rear center
could be a couple things. the oil sender unit could be bad or you could just be a little low on oil.
no replace it before it blows out your oil will go with it.the sender is direct feed from the oil pump.
The oil pressure sending unit on a 5.9L V8 is on the top rear of the engine next to the distributor.
