Ok, once upon a time I read another Ranger forum, a really good one, with a lot of postings.
 
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?

i dont know i had valvoline change it for me cuz me working i drive a truck for a living and i repair cars sometime and i dont have time to work on my own car i have heard that valvoline is shit when it comes to that i was told that it could be my cam chain theres 4 chains in the engine one for oil pump and two for the cam and one for something else but i guess they come lose until they get oil to tighten.. another question wile i have ur attetion i was told about putting synthetic oil on my truck but yet i was also told that u cant run synthetic if u dint break the engine in on synthetic my friend told me that when he did it to his car the car never made a sound even after he sold it so is it safe for me to put a synthetic oil in after i drain what i have in it out ???

People say a lot of strange, INCORRECT things about synthetic oil. In my opinion, you can put synthetic in at any time. Synthetic gives you better cold start protection and longer life (miles) between changes, compared to 'regular' oil.
 
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.

TIMING CHAINS BECOME LOOSE DUE TO THE TENSIONERS, THEY ARE MADE OF A PLATIC/NYLON MATERIAL AND WEAR OUT AROUND 100,000 MILES, YOU SHOULD REPLACE THEM A.S.A.P. BEST REGARD'S, REPAIR MANUALSTORE.COM

In reply to message 153
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 ?

One thing when switching to syn at high mileage is to watch for any oil consumption. If there is any above what was normal, I suggest you switch back to regular dino.

Which side of the passenger side or driver? also when you get in and turn key to on position, the check engine light should be on, and when you start to crank it 1 sec later it should go off to verify your Crankshaft Position Sensor is working properly. coils for the left side is primary, ECM control driver side spark on and off at ramdom. everytime you do any replacement on truck please erase memory,or your still be running in memory code. I don't check this site much please let me know if you got this problem solve. Bill, Repairmanualstore.com
