Fuel lines leaking. All lines need replacing.
2002 Chevrolet Silverado 2500hd. Consumer writes in regards to vehicle blowing out diesel fuel it was determined the injectors were bad and the low side pressure lines were causing fuel to enter to enter the crankcase.
Vehicle exhibited hard starting for a few days, and then was found with a large puddle of fuel under it in the morning, and was continuing to leak. Upon inspection, all steel fuel lines, at every point of connection, and at every brace, have thick, scaly, flaking rust. The corrosion is severe. In most locations, nearing the point of failure, and in at least one spot, resulted in a pin hole leak, with a significant quantity of fuel leaking onto the vehicle and the ground. The steel brake lines were also found to have a similar degree of corrosion, and will probably fail in the near term.
I have a 2002 Chevrolet Silverado 2500hd lt ext. Cab lb7 duramax 5 speed allison transmission, it has 114000 miles on it. This truck has been serviced as directed since new. The truck started using lots of fuel, at an idle it serged between 700 & 900 rpm's, and oil started blowing out the blowby tube. I have just found out that 3 fuel injectors are leaking fuel, with a possible head gasket leak,filling my crankcase with diesel, causing oil to blow out all over the truck, road and whatever else it can land on. While investigating what to do, to fix the truck I've found 3 other people I know that have duramax's, and they are going through the same problems. It's going to take me a year to save the money I need to fix this truck. I'm even going to do the work myself. In my opinion gm should be ashamed. They should at leased pay for the parts. The cheapest injectors I've found are $225. 00 apiece with a $125. 00 core charge. It's recomended that all 8 injectors be replaced at once. I've also been told these engines have defective head gaskets. That will cost another $600. 00 for parts, and $110. 00 for special tools I need to do the job. When I forked over the $40,000 cash inheritince money to buy this truck, I didn't signup for this.
Failing fuel injectors causing smoke out of exhaust on a duramax diesel truck. Gm knew of defect with injectors and only issued an extended warranty for 7 years/200,000 miles which ever occurred first. It was only good if you had an issue with the injectors at the time of warranty. I just found this out from a dealer and other owners of same type vehicle. If gm knowingly knew of these issues why did they not do a recall on said vehicles? I'ts really a matter of principle and moral ethics to do the right thing, rather than have the consumer take the fall for their lack of product design!.
I am concerned about the defective lb7 injectors causing a fire when they leak. Vehicle 2002 Chevrolet silverado hd2500 duramax diesel. Also causing another driver to crash from the puddle of diesel left behind when I have injector failure as has happened and will again since gm has no suitable replacement other than the defective part. Also curious about the total affect on the environment as this seems to be a common occurrence on 2001-2004 duramax diesels. Should I repair and then have concern of a vehicle fire? with my family onboard?.
My 2002 chevy silverado with duramax diesel engine broke down while on a trip from michigan to florida. The diesel injector casing failed causing the crankcase to overfill with diesel fuel then caused oil and diesel fuel mix to come out of the engine while traveling down the road covering the underside of the vehicle and roadway as well as vehicles directly behind me. The gm dealer in georgia stated we were in by mileage but out of the extended 7 year 200000 mile injector warranty by 1year and 4 days and the cost would be $6250 to replace 8 injectors. They offered a 10% discount off that repair. Subsequent calls to gm customer assistance were made to no end (they stated the 10% discount was their best offer). I pleaded that the time limit should not be a factor as this should not affect wear (injectors do not fail when they are not operating) my vehicle has 120000 miles on it (well under 200000 warranty as stated by the customer assistance rep). I paid extra for the diesel for longevity and fuel economy as I am on a fixed income but wound up being treated unfairly especially for a known problem and the fact that oil/fuel blowing out on the highway and vehicles is a safety and emissions defect. I would like someone from the NHTSA to consider investigating this aspect (time limit) and safety of drivers and fighting for me to get assistance. Thanks for listening.
