Oil Pressure

What would be the cause of my oil pressure not going up when starting, but does when running? Believe its causing the "check guage" message.

Weak pump, worn bearings, thin oil, bad sending unit.

Does the engine make odd noises when the gauge reads low? Is this at idle or just when cranking the engine over before it starts?

My friend's V10 oil gauge will swing on turns...

This is a bump

What engine? My 2005 6.0 in my E350 work van started doing that. The oil pressure sender went out. Got it replaced and it's been fine now for months.

Does it stick mostly when cold, then jump up to the proper pressure? If so, I just investigated this, and found it's very common (I have a 2000 F-150 with 5.4 engine). I simply went to Auto-Zone, bought the $10 oil pressure sending unit, went home and installed it, and that was it. On mine, the unit is right beside the oil filter. It took a 13/16 wrench and the only other thing is one wire which is a quick connect. Remember, when you take the old sending unit off, oil will run out, so keep a quart on-hand. I just did this last week, and even though I'm not a mechanic, it was a piece of cake.

I had this same issue on my 2000 F350 V10. It was a bad sending unit, First I would buy a cheap mechanical gauge and install it to verify pressure. The oil pressure gauge on these trucks is a glorified idiot light that causes the gauge to move in the normal range once 6-8 psi is detected. We need more info, mileage, what oil and filter you use. junk filters like fram have been known to cause start up issues.

Location of oil pressure sending unit

Where is the oil pressure sending unit on a 6.0 diesel engine?

It is in the 11am oclock position looking down on the oil filter housing. It is right next to the turbo oil supply tube. A freat time to upgrade the oil supply tube since i had to remove mine to get to the sender.

On the 6.0L you should also check the pigtail. If it's got oil on it
you may want to replace it.

cleaning the pigtail will probably do the trick rather than replacing it. Replacing the O rings on the turbo oil return tube, according to Ford, should be enough rather than replacing the entire tube.

The reason for replacement is if oil got on the insulation is will
turn to soft rubber then to goo falling off the wire. So if it
getting soft your better off replacing it because the wire strands
will wick the oil up the wire and make it fail someplace else.
