3 months old. I have no clue.

[...backstory...]
At work we have a 1990 C2500 diesel that used to get used in the 90's but has mostly sat since. We recently decided to give it a second life by getting rid of the useless winch assembly on the back and put on a flatbed. When I went to start taking it apart I noticed the electric lift pump wasn't doing so hot so I replaced it. The whole fuel system was coated with a thick, sticky varnish substance (probably due to previous biodiesel use) along with what appeared to be pulverized rust or something. So I systematically clean everything in the fuel system. The tank had to be emptied, steam cleaned, dried, repeat. After that, this new sending unit/dip tube went in. 3 months later, the truck is running like crap again. After checking everything else possible I finally decide to check the tank. That above is what I find, covered in rust/varnish/vaseline/?, plus a tank interior that looks just like someone had coated it vaseline and threw black sand at it. 3 MONTHS. How in the hell did this happen? Help me.

You know how at the pressure regulator on the fuel rail of some efi cars (can't vouch for diesels) will bleed of excess fuel pressure and circulate it back to the tank? Perhaps the fuel rail, fuel filter, intake plenum or something else that the fuel comes into contact is filthy with poo poo that the diesel can dissolve before going back into the tank. Or perhaps the fuel filter is so old its decaying into that black poo poo. Or perhaps it somehow has something to do with the truck being from a generation before the use of ultra-low sulfur diesel?

I have to ask, is a timing belt considered basic maintenance? My brother snapped his timing belt and gave all sorts of excuses as to why he didn't do it, including "it shouldn't have to be done/a shop should have told me/it's not basic maintenance."

The belt is cracked and looks terrible, along with the idlers and tensioner. Stupid, preventable poo poo like that pisses me off.

Timing belts are indeed considered to be basic maintenance (on cars that use them), though many people either ignore them or don't bother learning what maintenance is supposed to be done. They don't need to be looked after nearly as much as, say, oil changes and air filters, and if he's used to driving newer cars, he may not have owned a car long enough to worry about it before. Or he's just been lucky.

The owner's manual of every car with a timing belt should have a service interval specified. But that would require actually opening the manual. :effort: Depending on the car, it should be changed anywhere from 50k-120k miles and/or 4-10 years. Most cars on the market now have a manufacturer-recommended interval of 90-120k.

Hopefully it's not an interference engine. And tell your brother that it's not a shop's responsibility to hold his hand.

Yes. Especially when the failure of that single slice of rubber can mean an entirely wrecked engine. The timing belt is sacred and not to be hosed with.

If you want to be a dick about it (you do, he deserves it), pull the owner's manual, turn to the page about maintenance, and show him where it says timing belt. Then suggest that if it's too hard for him to read the owner's manual, perhaps you could read the rest of it to him or try to find a "book on tape" for him.

Pretty much the only warning sign you get that the timing belt is failing is the sound of your pistons smacking into the valves. So that would be "no".

If you are changing your timing belt at the right interval, you should be able to lay it down next to the new one and not tell them apart.

For your brothers sake, I'm hoping you mean serpentine belt. Which is also basic maintenance. If your brother is looking to blame this on a shop that didn't tell him he needed it done... then smack him for me.

No coating, just new fuel. It is possible that something got flushed back in through the return side because I couldn't clean every last thing.

If there is rust in the gas tank, just cleaning it won't fix it. It will just come back. The previous owner of my old Scirocco rally car "cleaned" the tank a year before I bought it. At the first testing day, the newly formed rust stirred up and caused tons of problems.

I had to drain and drop the tank, and send it to a gas tank renu place that sandblasted the inside of it and then coated it inside with a sealer. That stopped it. Then I rolled it :(

if you're not looking to replace it than etching it could work (although it's a total pita)

Get a bunch of phosporic acid (home depot sells phosporic etching acid with a rust inhibitor built in) and swirl a few (properly diluted) gallons around in your tank with some sand or nuts and bolts or whatever other abrasive to knock the worst of the rust off.

Then coat it with a tank liner if you feel so inclined.

Another option is electrolysis. (sorry to those who don't have the archives upgrade. you'll just have to google it)

As far as timing belt breakage being anyone else's fault, it's not. I am a service writer at a (lawnmower) shop that serves commercial customers for a major metropolitan area. Even if you buy our premium commercial tune up in the spring, you'll need to do a lot of the steps again by July and again in September. We're not going to give you a list of stuff to do, the hour meter is right next to the key switch. Don't bitch if your spindle bearings poo poo because you haven't greased them for 300 hours.

You read your manual and you tell me. Or just pay the piper.

A regular check is definitely a good thing too. The previous owner of my car had the belt changed but skimped on replacing the tensioner, which then wore out and the belt started slipping off the gear and shredding itself against the plastic cover. I took it to a garage for a yearly service and they were horrified when they removed the cover and it was full of shredded fluff and the belt was barely clinging on. After seeing the pics in this thread, I can just imagine the bullet I dodged there.

edit: and I'd put off getting it serviced by a month or two as well.

Good luck I had a pothole rip a tire straight off a rim once and didn't get poo poo. Chance are if you live in a populated area and there was a pothole big enough to do that to your car, chances are it did something to 10 other cars and you better believe less than half are getting settled.

But why would a local city council ever take time out of their "busy" agenda to legislate that they be held accountable for anything? I can't imagine how laws like that could ever be allowed to exist.



I was thinking about making a thread for "unique" solutions to mechanical problems - like how I once used a ratcheting cargo strap to compress a leaf spring on the front of a ford ranger so that I could get the spare tire on (in a pinch). I was doing it for a bunch of morons on the side of the road that I pulled over to help; the strap was rated for 10,000 lbs and I said "it shouldn't break, but if it does you can say that you curled 10,000 lbs. But if you here that loving truck so much as groan or creak, you get the gently caress out of there."

I wish I could think of more examples that I've used in the past, but they escape me at the moment. What do you guys think, what a thread like that go over well?

This. I once hit a manhole that had sunk 8-10 inches below the surface of the road and trashed a snow tire and the wheel it was attached to. When I contacted the city their response was "we've been running notices in the local paper about that for two weeks now, you should have known about it." The fact that I live 30 miles away and therefore was not a subscriber to the local paper didn't seem to register, nor did my question as to why they couldn't be bothered to put a cone on it to warn people.

Oh, and I never got any kind of reimbursement either.

Unless it's maintained by PennDOT, in which case they won't be liable for anything thanks to a law enacted in the late '70s. Assholes. I had three wheels get bent last winter.

There was one sinkhole on I79 that looked like it caused a semi truck to roll judging from the guard rail and skid marks. Unfortunately I didn't get a picture, but that section of highway has since been replaced. I just have to deal with the Turnpike now, which in some sections is worse. Since that's NOT maintained by PennDOT, people might have better luck getting compensated for damages.

That does not do the same thing at all. Phosphoric acid 'converts' the rust to non-reactive Ferric Phosphate. HCl just removes the rust and leaves the metal bare ready for more rust reactions.

I drove a '68 Dodge Charger with a 440 that ripped drivers side motor mounts out with alarming regularity (putting divots into the hood in the process normally). After having the bolt fail in a solid motor mount, I just gave up and used some old logging chain and bolted the drivers side of the engine down front and rear, directly to the frame. Worked like a champ.

Sadly, no photos of that era in my car life have survived to my knowledge.
