just got off the phone with a buddy that has an 03 xf4 4.0 . He has heard the same from his truck at times and addressed the dealer about it at a visit. dealer said it was the timing chains making noise until the tensioners got pressure. Beleivable I guess when you consider this motor has a chain from the crank to the "jackshaft" (old cam location) and then a chain on each end of the jackshaft to drive the cams on each of the heads (front drives the left cam and rear drives the right cam) and then (!)one from the crank to the oil pump. 4 chains in total. How much noise can a chain make? times 3? don't think the oil pump chain has a tensioner. Ed in havasu |

| I've been having an occasional hard start and constant rough idle on my 2002 3.0L Ranger Edge for about a year. I changed plugs, fuel filters, cleaned injectors, etc. but no change. Finally took it in to a good mechanic. He checked it out to confirm what he had already suspected: exhaust valve. My mechanic said Ford is having a problem with 3.0L's from around this year. | |

My vehicle is a 2002 Ford Ranger with a 2.3L 16 valve dohc and it's an LEV (Low Emissions Vehicle). The vehicle starts without any problem hot or cold. First start in the morning the idle speed is at about 1200 to 1300 rpm and then slowly return to its normal idle at about 8 to 900 rpm. the idle is smooth as silk and the engine performance is good for a 4 banger. After the vehicle reaches operating temp the idle begins to lope. Some times heavy enough to rock the vehicle but mostly just enough to aggravate the %$  # out of you and the engine performance poor. When at a stop the while loping the idle will smooth out and some times engine performance is good or bad. I have inspected the exhaust pipe and there is no soot evident so I suspect the vehicle is running lean. Incidentally it just passed the emissions test. I have cleaned the MAF, IAC and replaced the MAP. I have found no vacuum leaks. My brake booster was replaced due to a leak,; however, it did not correct the loping issue. No diagnostic codes have been tripped. I wish there was a way to test the complete system under load measuring components resistance will not tell you what it does under load also I am not a big fan of Diagnostic Codes on vehicles because there at too many variables in diagnosing the problem and could make some technicians lazy and not think beyond the codes. Please that is not an indictment of all technicians only the few and very far between that are out there Does any body have any suggestions, other than a can of gas and a match, on possible component failures or diagnostic techniques to locate a problem like this. Thanks in advance to every one sharing their knowledge and expertise.

Replying to: rangerman1998 (May 11, 2008 3:05 pm) For 4 Liter Rangers of about your age, there was a wide-spread problem of 'marbles in a tin can' rattle noise. But most of these were occuring at much lower milage. Some on almost new trucks, with just a few thousand miles. And some of them did seem to occur, or get worse, after an oil change. As far as I know, there was never much of an actual determination of what caused this. Loose wrist pins, piston apron slap, etc, etc, were talked about, but nothing was ever pinned down as the cause. Ford did not want to do much about it either, calling it 'normal'. A few people did get Ford to replace engines, and some of the replacements had the noise come back. The last I read about it, most people were just driving the truck, and the noise was not causeing much of a problem. With your somewhat high milage, I'm not sure if you have run into the same thing. About the only thing I could tell you is to stick your head under the hood and see if you can narrow down where the noise is coming from. The 'marbles in a can' noise came from deep inside the motor, the 'bottom end', such as the crank. You didn't put some strange oil into the truck? Did you get the correct filter? |
