need a hand real quick please???

I'm about to change my oil on my truck and replace the oil pressure sending unit/sensor. Is it pretty straight forward just unscrew the old one and snug up the new one? And one more question is it that big a deal if I add 1qt of 10w 30 to the rotella I bought? I forgot to grab an extra qt or two at the auto parts store.

Really difficult to say how to do what you ask. Nobody knows what engine or if its got a turbo or not. Lets say its non turbo. Then the sender is located way back behind the intake manifold air inlet. Even behind the tuna can looking thing attached to the back of the intake manifold. That can is called the crank case depressurizing valve. Sometimes its easier to look down thru the cowl to open hood slot for the sender.... As for mixing oils. Not a big deal. What you can do is install what you have that is made for this diesel and see where the level is on the dip stick. If its in the cross hatch marks then its ok. The very bottom of those marks is the add 2 quarts mark. We run about 10 quarts using the standard filter or 11 quarts using the power stroke filters.

Man I'm sorry I didn't even think to mention the motor. Its 7.3 92 non turbo. But I found the damn sensor lmao but only after I removed both gd temp sensors **** all over the ground damn what a day. Unfortunately I don't have a deep enough socket to back out the oil pressure sensor today. I took the simplicity of this engine for granted and rushed thinking I knew what I was doing and I got bent over.

Ok... Sometimes we jump into the water before we check for alligators too. I know I have been bitten a few times jumping into things with no idea whats going on. Learning something costs plenty too.

You don't have an adjustable wrench big enough for the sensor?

 

[larson]

Yeah I have a cresent wrench or two but I prefer a socket or a sized wrench so it doesn't strip/round the flats.
Its funny I have changed all wear items in this truck including the clutch by myself but I actually read up on what I was doing and had no problems what so ever. I jumped into something as small as the oil pressure sensor and coolant sensors and it was a disaster due to being impatient and not asking ahead of time or researching lol so my oil change turned into a coolant shower combination. Situation was personally embarrassing cause i love turning wrenches and I knew better. Its all fixed and plugged up now. Coolant gauge actually reads on my dash now to.

Sometimes the issue with the oil pressure sender is the electrical connection. Try cleaning the connector.

 

[madpogue]

The sender has HUGE flats, and it's a threaded (not seated) seal, meaning low torque. No way you would round the flats with an adjustable. Something of that nature, I'd be tempted to reach for a channel-lock if it were handy. You're not torquing down or breaking loose an axle nut.

Most every sender on the idi has a nps thread. That stands for national pipe thread. The only pipe size in the block are 1/8 for all oil ports and 1/4 inch for all coolant posts on the block. The heads are pipe threads in them also but I do not recall the size. Only the factory turbo blocks and the 1/4 inch pipe threads in all the oil ports.
