BioDiesel news & BioDiesel shoes.

It is... orange.

I few weeks ago one of the guys in my small BioDiesel co-op dropped off a barrel of waste oil he collected from a restaurant. I was a bit taken aback when I looked at the oil as it had… some odd coloration. Usually a barrel of oil settles in a way so that the top few inches look like new. That is clear, bright golden-yellow oil. When I looked at this stuff it was sort of shocking orange, and very opaque… almost milky. I though perhaps it had been shaken up in transit and have left it sitting out by the barn for a few weeks to settle. My worst fear was that it wasn’t really oil at all. Next in line was that it had been contaminated with something. Water if of course the usual waste oil contaminant, but this looked… weird. So last weekend I took a 1-liter sample and made a small test-batch. The oil had settled and was mostly clear, but still VERY orange. The test batch is done at ambient temps so it takes a long time. I let it sit for five days and above is how it looks today. Still not “clear” (it is unwashed though) and still… very orange.

Next I’ll subject some to the 3/27 Conversion Test and see how it does. My gut feeling says it is “good” and that the coloration is just some artifact of whatever it is they are cooking. The oil comes from a Mexican food place, so perhaps it is excess paprika, or maybe Chorizo, which are the only Mexican cuisine items I can recall that are unusually orange in color.

If it tests out well I’ll mix it with the rest of my (normally colored) waste oil and make some BioDiesel from it. Maybe my exhaust will make people think of nachos instead of french fries now? We’ll see.

Speaking of Home Brew BioDiesel I figured I’d share one of the risks of this activity: Shoe dissolving.

My soles have vanished

BioDiesel is one of the world’s great solvents. It attacks rubber with the ferocity of a shoal of slow-motion piranhas. Exposure directly to vegetable oils literally makes rubber vanish. I only wear one pair of shoes when I work out in the barn around the waste oil and BioDiesel, and the above is a photograph of their current state. This is of course after many years of use, but I think it is time to retire them.

Car Photo of the Day: Guzzler

Yesterday I spoke about prominent things on car’s bodies that make aesthetic and functional sense, and the big center-mounted gas cap on the C2 Corvette is certainly Truth in Engineering.

We ran with two Corvettes in the 2006 GTTSR as they were driven by friends of my father/co-driver. These guys could never pass by a gas station. Thirstiest cars I’ve ever been around. Their tanks are bigger than the E-type’s yet they stopped twice as often for gas. The Jaguar is NOT a miser by any stretch but these plastic machines suck down the go-juice like there’s no tomorrow!

Diesel Deductions

Above: Fuel Prices in Trafton, WA on June 1st, 2009.

As I noted back in February and March, the price of Diesel at the pump has been tracking consistently lower than gasoline this year. The past few years (since roughly 2005) when it was higher, in some cases quite a bit higher, seems to me to have been an anomaly. This is from the perspective of somebody who has been buying Diesel for three decades, starting in the autumn of 1982 when I took an old 1980 VW Rabbit Diesel with me to college as a sophomore. I wonder if this means the ‘Diesel is more expensive’ meme on the automotive enthusiasts websites will finally die? We’ll see.

Mind you, I haven’t bought any of the stuff at the pump since March, as I fill up on home-brew when the weather is warm. Nice to see the price staying where it should below gasoline though.

Car Photo of the Day: A sweetly bulging bonnet.

There is something aesthetic to purposeful variations to otherwise clean lines of a machine. The intake scoop of the C-type Jaguar. The twin bonnet ribs of the Mercedes-Benz 300sl (meant to provide clearance for the intake manifold and cam cover.) The big brake cooling ducts of the Ferrari 250P. The tidy little bump pictured above. Their purpose gives them reason for being. Form following function. Vorsprung Durch Technik. Ja?

There is something equally ugly to purposeless doo-dads applied onto a car made to make it appear sporty. The stuck-on ducts and bulges of the Pontiac Trans-Am from the “screaming chicken” era. Big wings on the rear of FWD “rice rockets”. The fake cloth tops on 80s luxury cars. These are out of place affectations. Automotive poseurs. These sorts of insults to our intelligence and aesthetics have appeared on some major-league players as well (Ferrari comes to mind) so I’m not just picking on low-hanging fruit here.

Bruised Sternum. The Adventures of the Moron Mechanic, part 37.

As I was driving into work this morning I noted that the skin on my sternum and upper rib cage is a tad sensitive. Feels as if I’m bruised. I stopped playing hockey years ago, so it is an unusual feeling these days. I racked my brain trying to figure out how I did this. Then it all came back to me… Saturday night Nick & I went down to the weekly “cruise-in” at the Burger King at the south end of town. I don’t have any photos as I forgot my memory card for my camera. (d’oh!) We wandered around looking at cars. The turnout was very good since it had been a warm sunny day and this time of year it stays twilight for hours at a time here above 48° N.

As we were packing up to leave I looked down into my open bonnet and noted a minor anomaly:

A re-creation of how I found the ball joint of the upper A-arm. In reality the circlip was gone however.

I noted that the grease cap of the upper A-arm on the driver’s side suspension had popped off. There is a “circlip” (Brit-speak for snap-ring) there that holds it down. The circlip had popped out but miraculously the cap, shims, and spring remained in place! There are two parts stores (Schuck’s & Auto Zone) very close to the cruise-in locale so I visited both looking for a replacement snap-ring. Unfortunately these retail establishments are really just ‘accessory stores’ these days. If I needed a carbon-fiber key ring, or some car wash they could have helped, but no actual parts could be found.

I put the cap and shims into a paper towel and gently drove home. The next day I went to NAPA and found the proper-sized circlip/snap-ring with ease. The hard part came next. I tried putting it on by hand. This involved squeezing my upper body between the tire and bonnet, and trying to push down on the spring with the cap with one hand, while installing the circlip with the proper pliers with the other. This was frustrating. It would have been helpful to have five hands… with very small, yet super-strong fingers. I have pretty strong fingers, but “very small” is never a term anyone would use to describe them.

What I really need is some device to hold the cap in the proper position while I use two hands to insert the circlip. I have a puller I used to detach the tie rode ends last year during my steering rack work. Unfortunately it is too small for the job. Conceptually however, it is just what I need. Back to the NAPA.

The puller I bought at NAPA

I picked up an adjustable puller, which should come in handy anyway, and started trying to finish this job. Did I mention there is the first JCNA Slalom of the season coming up this weekend? Yeah, I want to get this car fixed… as much as I’d like to take the TDI out on the slalom course it just wouldn’t be the same. Smoky, but not the same.

The problem with the puller was getting it adjusted and positioned just right, and then having it stay there. At least stay long enough to get the circlip pliers into action. Imagine me wedged like Winnie the Pooh in Rabbit’s doorway between the tire and the bonnet, barely able to peer over the tire down at the A-arm, as I gently try over and over to get the puller pushing the cap down properly. Countless times it either went off-center, the shims slid out, or the entire thing would pop off at the least opportune moment. A stream of expletives poured forth to accompany my usual crashing high notes of dropped wrenches.

It did not matter how I configured the puller: Long and holding the lower lip of the wheel-side bits, or short holding onto the upper A-arm itself. It always popped off when I least expected it. It drove me crazy. I flipped the puller arms around, tried different anchor spots. No matter what, just about when I’d have the thing positioned right… pop, clang, “@#$%! ^&*+! $#¡†!!!” This is how I got these bruises on my chest… the loud swearing. I’d bellow some choice four-letter word and my chest expanded rapidly, crushing my skin against the tire. Sure, there was some pain, but the ANGER and FRUSTRATION completely overwhelmed it. My rib cage is going “hey, um brain? hello? can you knock that off please… it hurts.” Meanwhile the brain is stomping around the room shouting like a madman in a bunker, oblivious to the body parts elsewhere sending urgent messages.

I finally gave up and pushed the car around and onto the lift, raised it up and removed the wheel. What happened next has me literally gobsmaked in embarrassment and shame. With the car off the ground the suspension hung there at an angle that I could plainly see the puller would not work. So I put a jack stand under the lower A-arm and gently lowered the car onto it. To my never ending shock the job became brain-dead simple with the car’s weight removed from the suspension. I literally just dropped the cap on, pushed it down with one finger, and the circlip went right in using the pliers to compress it. No drama. No struggle. No need to even use the puller. Presto.

Everything just went in with minimal effort.

Grease nipple back on, ready to drive.

So here I wasted several frustrating hours, wrestling with parts and car, wedging myself in a tight space to the point of nearly breaking my ribs… all for naught.

I guess the best lessons are the hard ones.

Car Photo of the Day: Rain on a Dino

Rain on a Dino

Here are some raindrops on an old Dino 308. The Dino belongs to Doug Breithaupt, the Rallymaster (who’s also running for Port Commissioner in Port Townsend) of the Classic Motorcar Rally, which is happening in just a few weeks. I didn’t choose this photo because of that impending rally though… but really because I have been thinking about rain. It has been about two and half weeks since we’ve seen any rain around here, which is truly an odd thing.

Of course, it seems to be raining everywhere else in the country at the moment, so I won’t complain.
