I have had issues with my truck losing oil out the crankcase blowby, and the engine finally went down at 82000 miles. It has injectors replaced at 70000 miles, then at 80000 miles, and the injectors that were in there were rusty.

After writing the Attorney General, Chyrsler finally got back to me in regards to deny my warranty solely based on no oil receipts. Wanted to talk to the mechanic doing the work on my engine, I thought I was finally going to have my engine covered.

Anyways, mechanic just called me the day before Chysler called me to let me know that my injectors are rusty.....water right.....Well, is there any other way that they could have gotten rusty? Truck sat in the lot for 4 months. Condensation???? The water light NEVER went on, and I never noitced any water when draining it, so I just can't figure it out??????? When Chrylser tested the fuel it was good.

They are now saying (not the mechanic, because he's not sure)that failure was related to bad fuel. But that would mean that it would have started a year ago, and about 14000 miles ago and I continually got bad fuel. When the dealer changed the injectors at 70 and 80 thousand miles, they did not note any rusty injectors, and the problem started before the first change of injectors.

FINALLY, this person was reasonble and I thought I was going to get my engine covered, but now the rusty injectors! CRAP!!!! I think that bad fuel is a legitimate reason for a denial, but I'm jujst not convinced that that was the cause, and I think it was just coincidental at this point.

Any opinions would be appreciated.

What happened to the engine to make it go down, piston?

I imagine the injectors were rusty on the outside. Dont think it would hurt anything.

Is a dodge mechanic capable of disassembling the injector and seeing if there is rust on the inside of the injector?

Id be taking the injectors to an injection shop and get there opinion. Yeah condensation could cause it. I dont think it would alter injection performance though. The fuel comes from inside of the unit. There is no way rust could get under the tips of the injectors unless there was water in the fuel.

Need pics.

How would the outside of the injectors rust when they are bathed in oil??

This is what I was thinking. If the truck is an auto, maybe the trans cooler failed and mixed coolant with oil? I have read of this happening several times. I would check the coolant and the trans oil and see if either is contaminated with the other.

If the vehicle is sitting 4mos maybe the oil partially evaporated and then condensation inside of the cylinder made the injectors rust. I dont know. Just a guess.

I cant imagine a dealer mechanic being able to disassemble an injector to see if there is rust in it. The guy is prolly just doing an outside observation.

Heck I dont know. We need pics of where the rust is at.

I haven't seen the injectors myself....I'm picking up the truck tomorrow so hopefully I'll get to look at them then.

Did you by chance do the mod for vent valves on top of the fuel tank? There was a recall on the 06' trucks for this problem that would let water into the tank. They never issued this recall for the 03' to 05' trucks that had the exact same fuel tank and problem. You got there butts by the long and scragglies. Push this issue and get your engine covered.

Good point, that is certainly another way to go at it.

I did do the mod, but if memory serves me correctly i did it at about 60000 miles, as I read aobut it on here.

Thanks

Sounds like you have never had a valve cover off
When you check for fuel contamination on our crd you look at the fuel filter canistor,FCA,Rail fittings,connector tubes and injectors last.If rust is found any where Chrysler will tell you to replace the entire fuel sysyem plus cleaning the tank to keep your warranty in effect.These high pressure systems are expensive and not very forgiving

lol naw never been into my engine...

My truck has 325k miles. I do all of my own maintance. Do injectors, valve adjustments. Just rebuilt my g56 and done a new clutch and rear main seal. Done metal doors in the heater box, ac compressor and recharge, all the bearings on the front of the engine. Steering box, and tie rods. Ujoints, carrier bearings, ball joints. Brakes, front wheel bearings.

I better stop. My truck is begining to look bad now, lol

Oh yea, rebuilt my rear diff last year, some 200k ago. My point is no dealer will ever see my truck, or for that matter any repair shop. Do everything myself. Have done all my own work my whole life...

Been driving since 1897, whoops 1987. Ive worked on all of my semis. This lil truck is like a play toy.

If there is rust showing on the injectors, it would be interesting to know if the rust is on the outside, which really wont hurt nothin, or the inside wish would be less good.

Ive found these lil fuel injector systems are very forgiving. I have only needed to replace the no.1 injector so far because of an electrical failure in the injector. The rest are original. I buy fuel all over the US and Canada. Ive gotten some of the worst fuel there is.. My truck runs great.. Dont run any extra filtration. No extra gauges, just the 4 in the dash. Dont need em. My big ears tell me when there is about to be a problem.

I run a luberfiner filter bought at autozone. I change em when my truck tells me, by not running well. Generally 20-25000 miles.

I abuse the heck out of my fuel system and it has worked great. I use ATF type F for injector cleaner. Best thing I have found to keep em clean.

So whatever dude If it hadnt been run in 4 mos. Rust could be found anywhere in the fuel system.

Take the injectors to an injection shop and they will be able to tell you what happened. No dealer mechanic is not going to help ya.
