Backstory, continued...
This was back in February of this year, in the lovely frigid Ohio weather. After calling the seller and talking to him, this is what I had found out:
- He believed that it had a bad water pump, as it was pouring water out of the front of the engine. He would simply keep refilling it, and only drove short distances
- The exterior picture was a couple of years old. He said that it had some minor paint peeling issues
- It's a florida van, and had only been in Ohio for a couple of years
- The heater fan only had one working speed
- The van had 109,000 miles
Due to the water pump and paint issues (still unseen at this point), I had talked him down from $4500 to $3500. The van was located across the state and was a 5 hour drive away. I decided that I liked the look of the van enough that I was going to chance a drive out there. I ordered a water pump and a new resistor for the heater blower, and about a week later made the trip.
When I got there, I noticed that the paint was peeling a little worse than what he described. The running boards were also cracked a bit here and there, and the front tires were pretty bald. Also, when I started the engine, it had some pretty loud lifter tick, even with a normal oil pressure reading. At this point I was really on the fence on whether to take a chance on the van. It was going to need some exterior work that I didn't plan on, and I knew I was taking a gamble with the engine.
I made a deal with him. I would hand him $3000, after which point I would attempt to replace the water pump with the limited tools I had with me. If it fixed the overheating problem, I would give him another $300. If it didn't fix the problem, then that $3000 was all he was going to get. I was reluctant, but I was hoping that if the gamble paid off, it was a really good deal. I figured that the worse case was that the lifter tick was a serious issue, and I may have to change the engine. At $3000, I decided that I was ready to take the chance.
The money was exchanged, and I got to work replacing the water pump.

As you can see, I brought a limited set of tools. It's not apparent in the picture, but the temperature was just below freezing that day and the ground was frozen. If you look closely, you can even see my feet hanging out from beneath the front of the van. I remember being amazed at just how tight everything was squeezed together and asking myself what I just got myself into.

I didn't have many pictures from this, but I spent 5 hours under the front of the van. I could not for the life of me get the fan to break free from the water pump. Somehow, I was able to wiggle the entire pump, fan and all, out from the bottom of the engine bay and get the new one in place.
I was feeling great. It was already later than I wanted to be there (I had budgeted 2-3 hours to change the water pump, and I was already at hour 5!). This didn't last long, however. After starting, going for a short drive then letting it idle for a while, not only did it start overheating again, but now that it had water pressure, water was spraying from the block! Upon closer inspection, one freeze plug was leaking, and there was a good sized crack above another. Yep, worse case news! A crack in the block!
The deal had already been made. Money had already been exchanged. I am a man of my word, and wasn't about to demand my money back - I knew what I was getting in to. But I still couldn't help but be struck by a feeling of panic. I was out $3000, and there was a van 5 hours away from home that I now owned, with a cracked block.
I spent a few minutes researching options on my phone, and many people had reported very good success using JB Weld and other adhesives to patch minor cracks in blocks, and ended up lasting for 100,000 plus miles afterwards. With nothing to lose and 6 hours already invested (on top of a 5 hour trip), I decided to give it a try. I ran to AutoZone, got some JB weld and applied it to the leaks.
To my amazement, after an hour of cure time, JB Weld really did seal up the leaks. There was not a leak to be found. I took it for another drive around the block, and it overheated again. I finally had to pull the plug and come up with a plan "B". What a long, pitiful 5-hour drive home that was!

Here you can see the crack radiating from the freeze plug.
