idoling problem after oil change
Had the oil changed at a valvoline quick change. Started the truck up and the oil pressure gauge took about 10 seconds to come up to pressure. There was some clicking sounds coming from the engine at this time. The check engine light came on and the truck started idoling very funny then stalled. Continues to do this.
I take it to the dealership and they said that the engine timing is completely out of wack. The computer is advancing the timing to full advance. They said they have never seen this on the 5.4L 3V. They called the Ford Tech Hotline and where told to pull on some timing sensoring/adjusting device. But to do this they have to order the part and tear down the top half of the engine.
The truck has been running great for the past 20,800 miles. What could have gone wrong with the oil change to cause this? Has anyone else had any problems after and oil change?

The dealership says they have narrowed the problem down to the Cam Phase Sensor (Cam Phaser). They said that once they get the part in they will be able to run more tests.
Sure hopes this fixes it. The truck has been in the shop 2 weeks now.

I had the same issue...FORD OVERFILLED MY OIL......GOT A ROUGH IDLE....when I slow down now to a stop my idle fluctuates up and down...never staying consistent.
They have not been able to fix it....maybe it is the CAM Phaser as well....I am about to DSB this truck if they cannot fix the issue THEY started.
Good Luck man!

The dealership says that using the wrong weight oil and/or not pre-filling the oil filter during an oil change can cause this.
The cam phaser is on backorder till Jan. 10, 2005 and only 17 units have been ordered by Ford's Service Division for Dealer Distribution.

While I use the Motorcraft 5W-20 in my 2002 F-150. I think it's a bunch of "pony pucks" what they are telling you about not pre-filling your oil filter and using the "wrong grade of oil" can cause the cam sensor failure. Unless you are using a real thick oil such as a 10W-40, 15W-50 or gasp, 20W-50 in the winter, then it may be possible. I have my oil changed at the dealer and I'm fairly sure that they don't "prefill" the oil filter. For a $22 oil change with a Motorcraft FL820S oil filter and 6 quarts of Motorcraft 5W-20 I guess I can't expect the dealer to take time to prefill the oil filter. So far I've had no "bad" noises and my UOA has been good with the dealer doing the oil changes as he does.

I wonder how you prefill an oil filter that lays on it's side in the installed position??? This is why the little plastic pan is under the oil filter-once unscrewed the oil comes pouring out. The dealer must flip the truck on it's side to retain the oil in the prefilled filter. I am with whimsey - horse pucky!

Not wanting to get involved the oil weight debate, but you can still prefill a filter that goes on sideways, or even upside down. Take a couple of minutes to fill it, topping it several times. You can then quickly install it, or even pour the excess off and install it slowly. The 'guts' of the filter saturate, and meet the requirments.

Dealer called yesterday and told me that the Cam Phase Sensor Sprocket that is located to the Cam by a Dowel Pin has a problem. The dowel pin hole in the Cam is elongated allowing the Sensor sprocket to wobel.
So they have ordered a new Cam for the truck and will let me know from there. The District Rep told them to replace the CAM and not the whole Engine.
Would anyone here agree with only replacing one Cam?

Single overhead cam. One cam in each valvecover.
From the technical description of the engine:
Ford’s new three-valve cylinder head uses a single overhead camshaft for each bank of cylinders.
Thus two cams, as opposed to four cams in a double ovehead cam system.
My point is that if there is a knock in one cam, you might want to check the other bank's cam. If the problem is a defect in the original cam, the problem will only be in one bank. If it was caused by oil failure, etc. it might be in both banks.

if this link works, it has a nice semi-technical description of the motor that is worth reading.
