Replying to: rangerman1998 (May 11, 2008 4:05 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? |

Replying to: rangerman1998 (Jul 14, 2008 6:46 pm) For a 1998 Ranger 4 Liter, I'm not sure you even have an over-head cam, which would require a cam chain. I was thinking they changed to the overhead cam in about 1999 or 2000. You might have a chain driving a pushrod motor, but I'm not sure you even have a cam chain. I've run Valvoline oil and thought it was ok. The problem with giving a vehicle to one of these oil change places, which I think is what you are saying you did, is you really don't know what they did unless you make a great point of telling them what you specifically want. They probably used 'bulk' oil, and who know what weight they used. If they ran out of 10-30, or whatever you should have in that truck, they might load you up with 20-50 if they had some lying around.

Replying to: 5150abf (Jan 09, 2008 5:09 pm) I am having the same problem on mine, same year, same engine, Off-Road version 99 Ranger, 4.OL OHV. I am getting a miss every once in awhile, I have changed my plugs, cleaned the mas, but still issue continues. I have also noticed a lack of power which I am wondering if I have a injector issue ? I have noticed that plug #4 seems to be always get black film around the outside. Any suggestions ? |
