Ok for 96 up magnum engines, pinging is a problem.  They no longer have EGR valves.  92-95 have EGR valves which hide a common problem to all Magnum engines.  Your problem is a leaking intake plenum gasket. It sucks air making a lean mixture and causing pinging.  It also sucks in oil and you may have noticed it using oil.  It won't smoke though.  There is a TSB on the intake plenum gasket.  There is also a TSB on rerouting the spark plug wires to help with pinging and another TSB or have the ECM reflashed.  Avoid the flashing of the ECM if you can.  Its called the "deathflash" .  It will get rid of the pinging but you won't have any power.  Fixing the intake gaskets should take care of 75-90% of the pinging and premium gas should take care of the rest.

What he said.

...and if it is indeed the belly pan on the manifold leaking, and you don't want to do this again, get THIS.

You're absolutely correct, Kendall. My mistake  ;D

The repair may have been done with the original gasket. Make sure you ask for the improved gasket that was phased into service in the late 90's. It has a steel reinforcement within the gasket, but even this will not prevent future failures. The gasket reinforcement plate from Hughes that Thaxton linked to is the best long-term solution with the stock intake manifold. Notice, I said "stock" intake. Use of the Mopar Performance M1 intake eliminates that pathetic design flaw (a real money-maker for Mopar service depts). But with the M1, you need to do other performance-oriented stuff. Don't get me started.

First of all, check the intake this way. Get a flashlight, climb up, open the throttle blades fully, and look at the inside of the intake. Does it look oily on the intake floor? If so, the gasket is shot. As mentioned, '96 and newer Magnums have no EGR, but it didn't hide that gasket failure too well. Anyway, the intake gasket is the biggie. Magnums have no knock sensors (funny, my '89 318 Shelby Dakota did....the plot thickens), so there are no provisions in the programming to automatically adjust the timing when pinging happens. While you're in there, put in a new 180 degree thermostat. Unless you have one of those fuel line dis-connecter thingies, it's gonna be a P.I.T.A. to work on the intake still attached to the truck via fuel line. I don't envy you the weekend "fun" you're gonna have.

As mentioned above, use the Hughes intake kit, if needed...that should take care of that problem once and for all.

If you have no time to answer the questions or try the advice then don't expect to fix it anytime soon!

One little tidbit, often times, the oil that gets in the manifold puddles in the rear of the manifold since it sits lower, and cannot always be seen through the TB.

The TSB that Chump linked shows a procedure to determine if it is leaking. I would try that test both with the engine cold and up to temp.
