Oil Pressure Light Comes On after 10 min of Driving

Hey Joe,
Are you sure it's the hydraulic oil low pressure or is it the engine oil low pressure light? Check the engine oil for being low, over full, filter change, right type of oil, leaks, air filter, spark plug, clean air intake, battery getting a good charge, if that stuff is ok, then find your oil pressure switch and change that out.
But it if it is the hydraulic oil light, check for leaks, that is a high pressure system so don't put your hand by hydraulic leaks use cardboard or something to check for leaks, a pin hole leak can cause severe damage to your skin from a high pressure injection from fluid.
Let me know if this helps and we can go from here

It may be your oil pressure transmitter switch at fault. There's many different oil pressure transmitter switches. Here are some generic images:

It could also be that your vehicle is due an oil/filter change.
Is your oil level ok?

It's unlikely to be your oil pump at fault.

1. Check your oil level
2. Is the vehicle due an oil/filter change?

The oil pressure transmitter switch simply tells the engine 'low oil pressure'. This usually happens at idling speed due to a faulty transmitter switch, low oil level or there's a need for an oil change as the old oil is no longer up to the job. Oil pressure switches are easily changed.

The important thing is that you aren't getting a warning light when driving at speed. If your oil level is okay and it isn't due an oil/filter change - it probably is the oil pressure switch at fault.

For your own peace of mind try adding an oil additive.

Remove the electric sender and install mechanical oil gauge to check that you have proper oil pressure. Bet ya the main bearings are not fitted correctly or the engine wasn't cleaned during overhaul and now bearings are trashed.

That could be from not having any oil pressure "oil pump failure, clogged filter, etc" or from a faulty oil pressure sending unit. More tests would need to be performed but is it really an oil pressure light or is it the change oil light. More info would be needed

I had the same problem I got a mechanic put it on a machine It said multipl misfiring and solution what it can be

The first thing to check it oil. The next thing to check is the pressure with a well know pressure gauge. The next thing to check is the main bearings for wear. If this is the problem, you will need to see if the vehicle is worth rebuilding an engine for or not.

2.7 ? This motor has oil problems if not changed every 3000 miles. Put a chrysler filter on it and the correct weight of oil, never use a fram oil filter.

you put a cheap oil filter on your car most likely. Put a GM filter or purolator or Motorcraft filter on.

you might try and change the pcv valve, my car hand a similar problem in the summer and i never changed it. the pressure blew my cam seal and i was leaking oil like crazy. i dont know if it will fix it but they are cheap. i would give it a try.

Depends on the model...I believe your engine is losing oil pressure. You may have a crack in your oil pan or bad oil pump. Oil Pressue sensors or usually located somewhere near on on the oil filter mounting.
