Explorer 98' engine Pinging
Hi guys,
I own an Explorer with 4.0 OVH or "pushrod engine" When I bought it, even up hill under load engine was very quiet. Recently I notice under same conditions , pinging sound start to come out from the engine. I understand it's not good if it happened for prolong time but with distributor less model , What to do to minimize or get rid of it? I switched fuel with Texaco, change plugs and cables but sound still exised. What else do I need to do to improve? Please help any ideas will be appreciated Dosio |

you can get the pcm reprogrammed @ a dealer . alot of times the timing is
readjusted when reprogrammed dosio wrote: >Hi guys, > >I own an Explorer with 4.0 OVH or "pushrod engine" When I bought it, even up >hill under load engine was very quiet.

Just move up one octane grade of gasoline, from regular to the mid-grade,
for example. That is why there are different grades, after all. Brands won't make a difference. =Vic= Bear Gap, PA "dosio" > wrote in message . .. > Hi guys, > > I own an Explorer with 4.0 OVH or "pushrod engine" When I bought it, even > up hill under load engine was very quiet.

I had the same problem with my '92, same engine. There was a jumper
on that model that could be removed to retard the timing. It hurt the gas milage and performance so much I put it back and ran premium gas from then on. There is a lot of discussion about this if you do a Google search of news groups. I ran the premium gas for a number of years until I sold the vehicle and moved up to a '99.

Very easy to do and almost free. Might very well fix it. Google for the procedure. You'll need some electronic switch cleaner and a security type torx bit. |

I have a 1998 XLT pushrod and have had similar problems over the later years, mostly in Summer when the temperature in NC/SC USA where I live is 90 Fahrenheit or hotter. For what it's worth, my XLT runs very well on Royal Dutch Pet. (Shell) fuels. That's all I use. 1. Clean MAF with solvent. and/or 2. Upgrade to 89 or 92 octane fuel. and/or 3. Replace MAF. > > |

Don't forget to check the intake for vacuum leaks( very common)
Might be a lean ping Spray carb or t-body cleaner @ the intake gasket area and EGR tube where it goes into intake and listen for rpm changing Or use a unlit propane torts BE CAREFUL<, don't set engine on fire "dosio" > wrote in message . .. > Thank you all , I'll try all suggestions out and post the outcomes > Dosio > "dosio" > wrote in message > . .. > > Hi guys, > > > > I own an Explorer with 4.0 OVH or "pushrod engine" When I bought it, even > > up hill under load engine was very quiet.

If none of the above worked, try using a product called Sea Foam. It is used
like an injector cleaner product, but you can pour into your engine thru the oil filler. The recommended amount is to use 1 pint (the entire bottle). Also try pouring another bottle into your gas tank. I tried this on my '98 V8 Explorer, which was making a ticking noise, and was producing a non-stop Check Engine Light, and agfter using Sea Foam, everything was fixed, including the CEL!
