Ahh. My first car. Definitely NOT a "cool ride" but such good memories.....
Short version:
Car:1978 VW Rabbit Diesel.
Bought for: $400 from my grandfather in 1987.
Sold for: 0$ Abandoned.
Long Version:
Let's jump in the "wayback" machine and travel back to 1987. I was 19, and in my first enlistment in the Navy. I'd just spent ~9 months at the Great Lakes Naval Training Center in beautiful Waukegan, IL doing my initial training as an Electronics Technician. I had 3 weeks leave enroute to a follow-on school that was located at Ft. Gordon, GA, just outside Augusta. Being without a car at Great Lakes wasn't too much of a hardship, there were plenty of public transportation options there. That would not be the case at my next stop. I needed wheels and I needed them to be cheap. At least my hometown in KY was on the way to Augusta.......
My grandfather came to my rescue and sold me his old "commute to work" car. He'd retired a few years earlier and it was just sitting there. $400 bought me a tan, 1978 Volkswagen Rabbit Diesel. 4-speed MT, 4-doors, 160K miles on the clock and one or two.....interesting....modifications. My grandfather had been a boilermaker for the Tennessee Valley Authority and the commute from his farm to the power plant was just about 80 miles each way. Pa hated stopping for fuel, so he had removed the factory fuel tank and replaced it with a 25-gallon unit that he had built himself. At 40MPG, that meant the car could go almost 1,000 miles between fill-ups. It also meant that the fuel gauge didn't work.....thus I ran out of fuel numerous times in that car....which is a total PITA as there is no manual "priming pump" on those cars, and getting it going after running the fuel dry took some doing.....
At 140K miles, the massive 1.5L, 50HP engine had lost quite a bit of it's compression, and in temperatures below 40 or so, it could be kind of (very, incredibly) hard to start when cold. My grandfather's solution was to put in a second battery and a big relay. When you turned the key to "start" it would put the batteries in series, sending 24V to the starter only, everything else would remain 12V. Sketchy? Yes. Effective? Absolutely. Crazy? Ingenious? Yep.
Honestly, it was a great little car. It was super-comfortable, handled fairly well, and, all thing considered, it was pretty reliable, right up till it wasn't. It was not even remotely fast however. 0-60 could best be measured with a calendar instead of a stopwatch, and it maxed out, on flat ground at 83MPH. I was dating my HS sweetheart at the time, and I made MANY round trips from KY to Ft. Gordon (~600mi each way) in that car. It could easily do the entire trip each way without stopping for fuel.
Mechanically, it was actually pretty solid all things considered. On one return trip form KY to GA the alternator died just past Nashville. I stopped at the Truck Stop at Monteagle on I-24 and the service guy confirmed that the alternator was shot. But, it was daytime, and not raining, and the only electrical power the car needed to run was just enough to hold the fuel solenoid open on the injector pump. He put the batteries on the charger for about an hour and I drove the rest of the way, over 300 miles, with no working alternator...... Can't do that with many cars. I rebuilt the alternator in the auto hobby shop on base later that week.
Those early VW diesel engines had a mechanical vacuum pump, driven off of the intermediate shaft to run the brake booster and whatever other vacuum operated things there were. It was located where the distributor would be on a gas VW. That thing failed on me twice. It was a simple diaphragm pump, much like a mechanical fuel pump, just larger. The first time it failed, I was able to buy a kit and rebuild it. The second time, the little cam-driven rod that acted on the diaphragm punched a hole through it's housing so I had to scrounge one from a junkyard.
Despite the "supercharged starter" modification, at temps below 20, it was almost impossible to get started after sitting overnight. My solution? A toggle switch underneath the dash that would provide 12V to the fuel solenoid on the injector pump, bypassing the ignition switch. If it was going to be very cold overnight I'd park it, put the transmission in neutral, set the e-brake, flip that switch, turn the ignition to "off" (car still running), get out and lock the doors. The doors and the steering were locked, but the car would sit there and idle all night.....
Eventually, at around 180K miles, the end was near. My buddies and I were in the car, on our way back from the Navy base in Charleston SC (we had to go buy some uniform stuff that we couldn't get on an Army base) in the middle of the August heat. We are tooling along down the highway at about 70MPH when, all of a sudden, that little car, all on it's own, starts accelerating like a bat out of hell!! It was almost like a Nitrous Oxide hit. The car had never had that much power before. I immediately took my foot off the accelerator, and it had mo effect whatsoever, the car is still accelerating. I stomped hard on the brakes, and once I got the car slowed down a bit, everything returned to normal. I was really confused, but, other than running a little hot (not shocking considering that it was at least 98 degrees that day) nothing appeared to be wrong. 20 min later, the exact same thing happens again. This pattern repeats several times, each time, it is harder and harder to get it to stop. Finally, it happened and no amount of braking would make it stop. I pulled to the shoulder, and turned off the ignition. No dice, the little engine is screaming like it's under WOT and will not stop. I stood on the brakes and popped the clutch.....the clutch just slipped (and stank) and the engine kept on screaming. Finally I got out, popped the hood and put my hand over the air intake tube leading into the airbox and the engine finally shut down. It did start again, and we managed to make it to within 50 miles of our destination before throwing in the towel and calling AAA for a tow.
When we got it back, I started poking around and saw that the inside of the intake manifold was covered in oil. The blow-by past the piston rings had finally gotten so bad that it was blowing motor oil out of the crankcase, up the PCV line and into the intake. The engine was literally running on it's own motor oil!! I'd never even heard of such a thing at the time. Remember, this was 88 or 89, way before the Internet and Google.
I pulled the head, dropped the pan, and popped the pistons out. Surprisingly, there was no detectable rod, piston, valve or head damage. I gave it a quick dingle-ball hone, new rings, rod-bearings, head gasket and timing belt and it fired back to life. It actually ran much better than it had since I'd owned it. All thing considered, I was pretty proud of myself.
Shortly after, I finished my school at Ft. Gordon and received orders to Italy. I drove the Rabbit back home to KY, parked it behind the barn at my grandfather's farm and left it there. To my knowledge it was still there several years later when the farm was sold. I have no idea what happened to it, but it's no longer there.
I'll say this for that little car, it was rugged, very well built, and simple to work on. I loved it.
