GM Repair Questions? Ask a Mechanic for Answers ASAP
I am experiencing a major exterior fuel leak on my 2001 duramax GMC. I am aware of the fuel leaking into crankcase problem but my dealer is telling me that my leak is completely different. He also says my leak has nothing to do with the extended 200,000 7 year warranty because that is an interior and my problem is exterior. Are others having problems with fuel rail leaks or exterior leaks? Can you tell me if exterior leaks are an ongoing issue with 2001 durmax deisels? I have ONLY 117,000 miles.
My dealer offered no info on any leak problems I had to find all info on-line
The return lines from each injector are under the valve cover. If these are leaking, you will not see it, but you will get fuel in the oil, and once the crankcase gets full, it starts blowing out the overflow.
I talked to them about ths already. I had a oil change scheduled and when I arrived I talked to them about the oil I noticed on my frame rail. They said they didnt know where the fuel leak was located. They couldn't pin point it without taking stuff off the engine. They told me it would cost 1 to 2 thousand dollars to take the top of the engine apart to locate the fuel leak. They said the leak was on the outside of the engine not the inside and they would have to take all the components off the top of the engine to locate the fuel leak. Then I looked online and seen this was an ongoing problem with the Duramax engines. I think I am being lied to because they do not want to open the recall bag because it would cost them money. If I have the oil tested to see if fuel is in it will that help me convince them the oil leak is enterior. I see no oil by the oil fill tube or the dip stick. Would those be the only two places oil could leak???
That is up to them. If you are a good customer to them, they probably will.
If I do have a leak in my fuel lines or injectors or anything else that is leaking fuel into the crankcase. Should the tech have noticed that my oil had fuel in it at the time of an oil change? Especially when I arrived for that oil change I pointed out the liquid on my frame rail?
last question for you... I thank you for all your info and for you speed in returing my answers. Great job! Very Helpful!!
If there is an leak on the outside of the engine as the dealersip is contending, shouldn't they be able to locate it before doing thousands of dollars of work? Shouldn't they be able to see an area where it is occuring?
Does it sound right that they content they can't see where it is leaking from but they are 100% positive that it is on the outside of the engine? I would think if they are trained in diesel engines that they would be able to locate the area of the leak with a flashlight and a mirror if necessary and be able to get some type of idea of what is leaking. all I am being told is that they have no clue until they do thousands of dollars of work just to locate the leak? Dosen't seem right to me.
very last question I promise you. Would another GMC dealership be willing to do this recall work? Won't the dealer lose money on fixing this recall fuel leak problems? Isnt that why this dealer is giving me the run aroung because it is going to cost them money? Again that was my last question, you have been so very helpfull I plan to leave you 100 positive feedback.
Thank you sir
If you are past the mileage or date, then no. This is not a recall, rather it is a special policy that covers the injectors for an extended period of time.
The dealers are not out money as GM pays them for the recall work. The tech would rather dot he work on your dollar as the time is better. WE don't do well on the warranty times as they are much less that the actual time.
