A d.f classic

Many years ago, in a Bothell location far, far away, the df-tech geeks went out to the dumpster to “retire” some old gear. Damian recorded the event for posterity and it has even had a few moments of net-fame here and there.

Boy, it was fun.

Update on the Moron Mechanic.

Filed under: Cars,Diesel — chuck goolsbee @ 5:12 pm

I rummaged around in the garage today, and found some hose of the right inside diameter. I cut off a chunk about 5cm long, forced a machine screw into it. It fit like a charm. The guys on a Diesel list I’m on suggested the screw… directly into the injector. I decided to take a more moderate and reversible approach.

Seems to be working fine. I can grab the right part anytime now.

The guy’s a dork, but…

…I have to agree with most of what he says here.

The current administration is made up of liars and people incapable of doing right, the war is a disaster, Iraq’s future is destined to be far worse than its past, and we, the USA, and specifically the Bush administration has squandered the opportunity of all time.

I guess even blow-hard New Yorkers are occasionally correct.

Bush supporters keep chanting “cut and run” in answer to his suggestion. But really… other than “stay and watch our soldiers get killed” WHAT THE HELL IS THE STRATEGY? Seriously. Has anyone in the Bush administration EVER laid out for us what their strategy actually is? What is the PURPOSE of this conflict? What is the exit strategy? Can they finish ANY job they start? Remember Bin Laden? Afghanistan? Hello?

Ugh.

The Moron Mechanic Strikes Again!

This is the engine of my “daily driver”… a 2002 VW Jetta TDI. It is a wonderful machine in that it is remarkably fuel efficient. Without any magic tricks or massive banks of batteries, or anything even remotely “ccol” to a Hollywood celebrity, it gets mileage figures that equal or exceed that of a Hybrid. It has 105,000+ miles on it, and just about every one of those miles took about two and half ounces of fuel. Every one of those miles have been essentially trouble free as well. All of my troubles with this car have been self-inflicted. =) The car itself has been wonderful, with only a single mechanical defect (the passenger-side window fell into the door not long after I bought it, and VW fixed that for free under warranty. There was later a recall for that one issue.) in all the years and miles I’ve had it.

There has been one other issue. The #1 injector started leaking last summer. I suspect that may also be self-inflicted, or it could be clogged due to age and soot build-up. So I set about to remedy the situation. I bought some new injector nozzles, and sealing washers and waited for a day when I could get it all done. I picked today (well… technically yesterday.)

It all started well enough. I printed out the Nozzle How-To from the TDI Club website wandered out to the barn and went to work.

Above you can see the dirty area around the #1 injector (far left side of the engine) where fuel has leaked out and dried on the metal. I’ve also cracked off the fuel lines and removed the glow plug bus bar, which is leaning up against the air-intake pipe from the air cleaner box (right side of the frame.) The shop towels are there to soak up Diesel as it drips from the injector pump and fuel lines.

Above is a close-up of the #1 injector area, and the really yucky fuel residue. Note the nitrile rubber cap opposite the return line. It becomes important later.

Above is the hold-down bracket for the #1 injector after I’ve cleaned half of it. Yuck.

This was taken just prior to the hardest part… working the injectors out of the head. I eventually went into town in the pickup specifically to buy a 15mm “crowfoot” socket wrench to work these loose. You basically work them out by rotation back and forth until they loosen. Once they loosen they lift right out by hand… but getting to that part took a LOT of working the parts around with the wrench. The tape is there to keep dirt out of the tops of the injectors while I’m working in there. The #3 injector is different from the other three, as it contains some of the electronic feedback mechanisms in it. The grip surfaces of it are subsequently lower and shorter. I had to remove the glow plug from the #3 cylinder to get enough room to rotate the injector with the crowfoot wrench.

Since I am not a very good mechanic, I try to stay organized while I work. Here is an example. The paper is the printed out HOWTO and I place removed parts on the pages where the correspond. This reminds me when and where to replace them. You can see the injector hold-down brackets on the shop towel. Yes, that is the Jaguar under there. There are three layers of car cover so don’t worry. I would never put heavy parts on it!

Above you can see all the injectors are out (plus the glow plug from #3.) I’ve started to clean up the dried on fuel residue and dirt. I used a shop-vac to suck the stuff out of the injector holes, along with a shop towel soaked in solvent wrapped around a flathead screwdriver and gently swabbed around in the hole. Eventually I got the whole area fairly clean and the injector holes spotless. The area above and around #1 took a solvent soaked toothbrush and a LOT of elbow grease!

Above are my very sooty injectors. The nozzle replacement process is pretty simple, but requires some patience and precision. You have to put the injector body in a vise and rotate off a retaining collar (the darker grey area on #1 & #3 injectors.) Then you extract the nozzle and the copper sealing washer at the base of the nozzle. The rotation took a lot of muscle. Removing the nozzle required soaking the bottom half of the unit in Diesel fuel until it could be worked apart. Installing the new nozzles (still wrapped in paper and lying between the injectors above) involved laying onto the upturned injector body still in the vise, lining up some pegs in holes, then carefully dropping the retaining collar back on without upsetting the nozzle. All during this you can’t touch the tip of the nozzle with anything lest you clog it up with dirt or somesuch.

Above: the shiny new nozzles installed in the injectors.


The fuel return line looked a bit worse for wear, so I figured I’d go run into town and grab some new ones. The copper sealing washers I bought from VW were also a bit too tight and much thinner than the originals. So I grabbed a washer, one short length of fuel return line, and the rubber cap off the #1 injector and drove into town with Nick in the pickup. Since the #1 had been leaking I figured it would be a good idea to replace any of the rubber parts around it. Hence the cap. We went to NAPA. They were out of that size hose, and didn’t have copper washers in the size I needed. So we went next to Campbell-Nelson’s VW wrecking yard, where I got the replacement air cleaner box and the sealing washers. They didn’t have these sorts of things “in stock” but sent us out to the yard to see if we could find them on a wrecked car. Nick and I wandered around the yard in the rain, with directions on where to find the one Diesel car they had… an identical 2002 Jetta TDI to mine… same color, everything. Except it had been “T-boned” on the passenger side. The engine was gone, so no way for us to get the parts we needed. It was sad to see the hunddreds of wrecked VWs. There was one Passat with a gorgeous leather interior that was getting soaked by the rain as its windows had been smashed out in an accident! Oh well. We went home, stopping at Schucks and AutoZone with ZERO luck on the fuel return line (I didn’t even bother trying on the other parts!)


When I arrived home, I went back to the barn to finish up. I was able to make the copper washers fit OK with a bit of work. The injectors went back in fine. Everything came together well. UNITL…

I reached into my coat pocket to find that rubber cap for the return line and IT WAS GONE.

“D’oh!”

I must have dropped it at some point as we were out parts shopping!

I felt like a total moron.

I was able to rig up a plug. Enough so I could get the engine running again, but I will have to source a more permanent replacement before I drive the car any distance. What a dolt.

Ouch!

In a way I’m glad the video cuts out before the impact.

Duesy.

I recently saw that this car is in the list of “top ten highest prices cars” or somesuch. I photographed it at the Amelia Island Concours in 2004. An amazing machine… it is HUGE.
