1998 Ford Windstar v-6 starts out fine but pings when it gets to tempeture, the vehicle does NOT overheat at all but eventually after about 30 min of running sounds like a diesel train. I took to a mechanic but after 4 hours of checking things he said it is 90% chance of being a bad computer. I am not a mechanic but am a working father of 3 boys who has to manage every dime and would like to ask the community their thoughs on this. I am willing to buy and pay to have install but cant afford to keep changing parts. Does anyone have info input or maybe a similar situation? Thank you in advance!

Re: Pinging sound on 1998 Ford Windstar
Right try this cockney cowboy bodge and see if it works ---three squirts of fairy washing up liquid in the oil filler and about half a pint of diesel ,use car as normal for a about a week and see if the noise gets less,if it does then drop oil and refill and repeat ,if it doesnt then dont bother because the hydraulic tappets are not the cause of the noise.To be honest without hearing the noise its difficult to diagnose and i have to rely on information you have supplied from other mechanics so i can only make suggestions like the one above .But i have had this sort of thing before and i know that this works on vehicles that have not had regular oil changes

As a vehicle ages, the timing gets off, and the Octane of fuel will compensate for an out of timing vehicle.
Bad gas is main culprit, also dirty/clogged fuel filter, or clogged carberetor or injectors!
Use a "GOOD" fuel system cleaner for the next 3 tankfuls, and use a higher octane fuel at the same time!!! This is important. After 3 tankfuls and 3 additions of a Fuel System Cleaner, go back to a lower octane fuel. Drive up a hill and see if the problem is gone. If not, then either take it to a mechanic and check timing, hopefully you replaced the fuel filter by then.
Some Ford engines are not equipped with knock sensors. Yours may be one of them. Located in the wiring loom, close to the ECM, is a "jumper" that when removed retards the timing 4 degrees. This should correct your pinging problem. as for the missfire try changing the plugs and wires .also check the egr valve. thanks
Timing is only one of many causes of "pinging".
Before altering the factory setting or connections, please do each of the following:
1. Change your oil and filter.
2. Add fuel system cleaner to your gas tank.
3. Spray fuel injector cleaner into your air intake (after the air filter) while the engine is running. (Do this slowly enough to not stall the engine.)
4. If you use "off-brand" gas, consider adding a $1.00 bottle of Octane Booster - from the Dollar Store.
I suspect that one of the above will correct the problem. If the Octane Booster corrects the problem, then you do have a timing problem (too far advanced). Take it to the Ford dealer and ask if they have a Service Bulletin on the engine due to pinging - and ask how they would alter the timing. Then either do it yourself or pay them a pre-agreed amount to ****** the timing 2 degrees (no more!!)
pinging noise low octane. mix gasoline half and half.half 87 and half 89.run it severals days if it still ping have it scan to check detonation sensor.a bad detonation sensor will also make car ping alot.
The pinging noise that you hear is detonation occuring in one or more of the cylinders. The dealer suggested to move to a higher octane inorder to prevent this because the higher the octane the higher the prevention of Detonation.
The Probable cause of the pinging, would be that you refilled with a bad batch of gasoline. Premium should be used in this vehicle no matter what. Due to the clearances of the heads and valves in the motor. And also due to the material used to make the cylinder heads, if severe detonation occures then the valves could be damaged.
