Ford F-150 - 1997-2003 :: 2002 - No Oil Pressure And Rattling At Idle
I bought a 2002 f150 4x4 with a 4.6l. It has 250k miles on it. a couple days ago. It had no problems at all during the test drive or for the 150 miles home. Yesterday after it warmed up, the oil pressure dropped to 0 while at a red light and had a rattling noise. Not a knock but more of a rattle. I can't isolate where the rattle is coming from. Oil pressure comes back with just the slightest of increase Of RPM and seems To have plenty of power while driving. I had read to check the pressure manually but with the noise I sense there truly is a problem. the oil appears clear and is full. What I should be checking on this.

At the above speeds my truck has a rattle/ticking. I think its the cats but I'm not sure. I checked all the obvious like the heat shields and stuff. The truck has 118000 miles on it and has been in So. Cal. its whole life.

I am having an oil pressure issue on a 2000 F-150, 4.6L.
I recently put a new set of heads on the motor because of some valve damage. Anyways. The oil pressure gauge in dash would sit at around 3/4.. Drive it a couple miles and every time you would get back to idle (stop sign) it would drop to zero and the light would come on.
You could also hear it make a little noise like the top end wasn't getting oil. (Didn't run at idle long..) I figured it was obviously starved of oil so I put a new oil pump, timing chains/guides/tensioners on. (Which I probably should have done with the heads.) Same issue resulted, but no funny noises when the gauge drops off.
Suspecting that the sensor may be faulty and the dash gauge being useless anyways, I dug an old mechanical gauge out of a box and installed it. I'm getting similar oil results. (Under 25psi it seems.) I'm not sure if the gauge has just gone to crap over the years of being in a box. However, the previous low-oil pressure issue seems to confirm it's not the gauge.
I cleaned the oil pickup when I had the motor apart. It didn't seem dirty, but I sprayed it out regardless. The motor looked fairly fresh when I had it apart. Bearings looked solid, cylinder walls even looked freshly honed. From what I hear, the motor was a low-mileage replacement.
So what could cause a low-oil pressure issue? Bearings seem fine, oil pump is brand new.
Ford F-150 - 1997-2003 :: 2002 - Oil Pressure Light On / Gauge Went To Zero?
2002 F150, 4.6 V8, 140k miles. Oil level good, oil was changed 2 months ago.
Driving along one day, out of the blue oil pressure light comes on, oil pressure gauge went to zero.
Engine did not run hot, no bad engines noises that I can hear.
Upon restart, oil pressure will be up on the gauge for minute or so, then goes to zero and oil light comes on.
Asked around, some say oil pump, some say oil filter or pickup tube.
Ford F-150 - 1997-2003 :: Oil Pressure Gauge Jumps Around / Sometimes Shows No Pressure
'97 F150 4.6L 4wd automatic... My gauge jumps around, sometimes it works and other times it shows no pressure. Could that be the oil pump? Or is the gauge most likely bad? Whats the actual purpose of an oil sending unit?
View 6 RepliesFord - Explorer :: Sudden Loss Of Oil Pressure / Engine Rattling / Check Gauges Light On
So, last December, I was sitting at a stop light, when my engine suddenly started rattling. "Check Gauges" light on, ZERO oil Pressure..
Took car to mechanic, he removed the valve covers, and scoped out the timing chains with a camera, and found everything intack, and no chips out of the timing guides (125K miles on the engine). no sludge, nothing.
Engine runs fine (for 5 seconds at a time) no issues. Removed Intake to check the Oil Pump Drive Gear, all is well.
Removed Oil Pan Inspection Plate, All is well. ZERO plastic chips in the oil pan from timing guides, ZERO sludge, all is clean.
Back up to top of engine, pull the Oil Pump Drive Shaft using needle nose pliers from the top of the engine. BUT!!!
Only the top 8 inches of the Oil Pump Drive Shaft comes out! The bottom gear is not present! Is it still in the oil pump?
OK, so I need a new oil pump drive shaft. no Problem.. BUT: how do I get the broken oil shaft out of the engine before I put a new one in? Use a magnet? Rubber hose?
Ford F-150 - 1997-2003 :: A/C Compressor Is Rattling And Grinding
My air conditioning compressor is rattling and grinding. I am trying to determine if I need a whole new unit or just a clutch assy. I can say this, when running it's rattling, but when the clutch engages, it clears up.
Would I be right in assessing it's the clutch? 1998 250 5.4 .....
Ford F-150 - 1997-2003 :: Truck Started Rattling From The Exhaust
1997 F150... Truck has slowly started getting worse and worse performance. About 3 weeks ago the truck started rattling from the exhaust, Towing my trailer the other day, the truck had NO power, I thought it was the plugs, so I replaced them.
Now the rattle is worse (no lose heat shields). I am blowing the little tubes off the drivers side exhaust manifold, the ones that go to the DPFE sensor.
Did I mention, that the truck has no power, sluggish, now I am dumping hot exhaust fumes into the engine compartment. Still got the rattle underneath.
I think the cat is plugged up on the drivers side. (which probably explains all my symptoms)
Any other reason for the rattle literally coming from the drivers side cat and the little tubes being blown off?

I have had a noise in the front of the engine of my 2002 f150 4.6 for about 2 weeks. On my way home my oil light came on made a knocking noise and shut off. The engine would not start back starter would engage but not turn motor it was seized. i called a tow truck and had it towed home. The next day just out of curiosity I tried to start it. It fired up ran and built oil pressure. If the oil pump froze will that make it . Can the oil pump make the engine act seized up?

We just purchased a 2003 Ford Lightning with 114,000 miles on it. Had oil changed. Had to get floor master mufflers attached back on. Ever since then now when it gets up to 65-70 mph it starts a terrible rattling noise , almost sounds like a spark knock. Truck starts riding very rough. We have have only run premium fuel and even put in some gas treatment to see if this works, it hasn't, only getting worse. We are currently out of town and trying to make it home but don't want to cause any major damage to it. All the gauges are fine. Just the rattling and shaking...

View 10 RepliesFord F-150 - 1997-2003 :: Oil Light Is On / Gauge Dropped To Below L / Engine Started Making Noise
I drive a 2001 Ford F150 4.6L , Miles at 175,000+ (a little more but no more than 176k)
Situation as it happened : Driving home from work for lunch, about halfway home I notice that my Oil Light is on and the Gauge has dropped to below the "L." Engine started making noise, best I can compare it to is to the sound of a diesel engine when it's idle. Immediately pull over after noticing this, shut off engine for about 5 mins, check oil, oil is fine. Turn truck back on, light is off, gauge is normal, and noise isn't as loud as it was before. Drive rest of the way home no problem. After deciding on driving the truck back to work (I know i shouldn't have but I have no other means of transportation, and I work at Autozone so I wanted one of my managers there to check it out) I turn on engine, everything is fine, no oil light, gauge is in the middle of the "H" and "L", only thing wrong was the engine noise, except like earlier it wasn't too loud or shaking the truck. About halfway to work, I come to a stop sign, Oil gauge shoots down below the "L" and the oil light come on.
As soon as that happens engine starts making same loud noise as before (diesel truck idling.) I push the gas to get past the stop sign, and instantly truck loses power in pedal and just shuts off. Make it to side of road, hasn't turned on since. Never had any problems with the truck since I bought it 5 months ago, changed the oil 1 time about 2 months after I bought it. I'm just hoping my engine hasn't seized up on me.
Not sure if this matters, but about 4 days prior to this, truck was making a rattling noise, almost like shaking a can of paint , under the front drivers side, in the suspension. Was told those were probably due to my sway bar link bushings being busted.
After some research on here and other websites as well, I have come to find out that this is pretty common in most Fords? Most people recommend changing the oil pressure switch, and others say it could be the oil pump? Was planning on changing out Oil Pressure Switch, and changing the oil filter/oil , and fuel filter as well. Not sure what else I could do?
Ford F-150 - 1997-2003 :: Cannot Get The Oil Gauge To Read Pressure
I changed the sending unit and replace the oil filter with a motorcraft unit and still can't get the oil gauge to read pressure. Since it is a gear oil pump I don't believe it is the pump.
View 2 RepliesFord F-150 - 1997-2003 :: Oil Pressure Gauge Drops To Zero
I have an 01 F150 Lariat Supercrew 4x4 with the 5.4 Triton. The truck has 222,000 miles on it. Recently, I have noticed that when I am stopped at a stop light/stop sign while in gear, the oil pressure gauge drops to zero and the light comes on. As soon as I let off the brake and give it gas, it pops back up to normal. While driving, the needle never moves and stays consistent until I stop again, and back down to zero it goes.
If I put the truck in Park, the pressure goes back to normal. Same with neutral. It seems it is hit or miss and does not do this all the time, but I just wanted to see what your thoughts are. After doing some research I am leaning towards an oil pressure sensor/sending unit.... The truck runs perfectly fine, I just want to make sure it is not something more serious.

How do you get to the oil pressure switch on a 1998 F150 4x4? I can see it over the top of the front axle but can't find any way to get my hand in to unplug the sensor wire. Do you have to unbolt and drop the axle down a couple of inches?

I've got a '98 F150.throwing codd 402, excessive flow EGR, also the oil pressure drops to absolute zero only when gear shifts but comes right back up. No knocking or other distress sounds in engine. I know I'm in need of an oil change. I already searched a bit and decided to swap out the DPFE sensor which I did purchase from the dealership. No code as of yet but what could that pressure drop be? Could a simple il change and filter fix that?
