Did I ruin my engine ???
'02 2500HD 4x4 with 6.0L gas engine.
Inadvertantly put in about 5 gallons of old, yellowed gas from another vehicle that had been sitting idle for about a year. No doubt had water in it too. 2 days later, the 2500HD wouldn't start in the morning and making very scary ($?) clanging noises. After many, many attempts, truck finally started. Truck runs fine now (still sometimes hard to start though) but there is a VERY distinct pinging noise in the engine. Friends tell me that's the sound of the lifters, and that even though the sound is concerning to me, no harm is being done to the engine. When all the bad gas runs it's course through the engine, everything should return to normal. When I first put the bad gas in the truck, it was about half full of clean gas. I then filled it up with additional clean gas with the intent of diluting the bad gas. I also added a bottle of fuel injector cleaner, and a bottle of "fuel preservative". At this writing, that tank was down to about 3 gallons remaining and I just filled it up again with 23 gallons of Chevron Supreme. Still making the pinging noise. Can anybody here help me with explaining what might be going on with my engine, and am I ruining it by continuing to drive it like this? Thanks in advance for any help... Mike Tucson, AZ |

My concern wouldn't be that the gas was old, as diluting it like you
did would have pretty much taken care of that issue, but I'd be worried about how much water might have been in the gas. One big slug of water could have damaged things internally.

A friend said that it was sticking lifters, and that I should change the oil but put one quart of transmission fluid in it. That solved the problem for about four years, after which I added a quart of transmission fluid again. But if the problem goes away after another tank of gas, I wouldn't worry about it. |

Normally a "pinging" noise is associated with fuel that is incorrect
octane, although most modern engines have knock sensors which retard the ignition timing if it detects the engine knocking, or pinging. The noise began when you put the bad gas in it, no? Lifter noises are usually described as a ticking noise. Without actually hearing the noise it's impossible to say for sure, but I wonder if it didn't raise hell with the injectors when you ran that turpentine through it, since that's when the noise started. And now having pretty much good fuel in the tank again didn't make the problem go away. If it is indeed pinging that can damage upper cylinder walls. I'd recommend taking it to a pro and have him diagnose it, because you could indeed be damaging it by driving it. They probably won't even charge you anything to just listen to it, and there might be a technical service bulletin circulated to the dealerships addressing this if it's been reported to happen by other owners of this model of vehicle. The vehicle's still fairly new. |

Do a compression test and a leakdown test on all cylinders, test manifold vacuum at idle and at several rpm levels throughout the motors normal range, at start up and through normal op temp.what do you notice ?. if you dont notice any radical differences between cylinders(compression and leakdown) or between hot and cold vacuum readings(manifold at various rpm) then I wouldnt worry about it. Of course a friend of mine had his vehicle vandalized , a dude poured two liters of orange soda in his gas tank(admitted to it , volunteered info after a severe severe beating)(in middle of really, and prior to a worse session and a talk with the cops followed by his arrest) truck was a gmc with a v6. Needed new injection header gizmo(looked like a spider, forget the specific name) and due to bent valve stems and a warped head, the dealer he wound up going to replaced the entire motor to the tune of roughly 7 grand. Luckily the police report and the guys coerced admission /arrest onvinced his insurance company to cover damages and cost of repairs minus his $500 deductable. Look out for watery **** in fuel, it does not compress well when it is in sufficient quantities and it will destroy the hell outa a motor. Larry got lucky as hell. Hopefully , you are even luckier.
