As I wrote in my last post, I've been chasing small leaks for over three weeks. The nagging oil leak from the fuel pump continued to drip. The coolant also continued to drip off the rear of the block. To add insult to injury, I discovered that our rebuilt carburetor was dumping gas down the intake at an alarming rate. This hadn't been apparent before, with the engine idling high. Once we began fine-tuning the motor, though, and adjusted the idle to where it was supposed to be, the engine couldn't burn off all of the excess fuel. A quick look down the carb with a flashlight told the story.
My first thought, and the obvious issue, was a speck of debris in the needle seat. I called the carb shop, and they suggested I take the carb off, turn it upside down, and apply a tiny bit of air into the fuel intake. I did that, reinstalled it, and still the fuel gushed forth. Frustrated, I packed it up and shipped it back for a professional evaluation.
Turning my attention, again, to the leaks, I took last Saturday morning to raise the car on blocks and drop the transmission. The leak
had to be coming from the real freeze plug, which was the only one I hadn't replaced. The tranny removal went pretty smooth, as would be expected on a nice clean engine and car. Even on my own, I was able to get everything disassembled in about 90 minutes. Daniel had been completely booked for the previous week with school and work, and was so this day as well. It was just as well, because I felt somewhat responsible for this problem and I didn't want him to get discouraged. So, in the peace of the morning, I popped out the "bad" freeze plug and installed yet another one. I couldn't see any signs of drippage, but where else could it be coming from?

| Hiding behind the starter |
Confident in my repair, I filled the engine back up again with coolant and set about reinstalling the flywheel, clutch and pressure plate. As I torqued the last bolt on the bellhousing, I was bombed right in the forehead with....a drop of water!
After lying under the car for a good five minutes of total frustration, I took the drop light and a dry rag and began going over every possible joint and seal. I could see the coolant oozing along the gap between the oil pan and block. Like a trail of tiny ants, I continued to follow until the trail stopped, about halfway forward of the block. OK, it has to be somewhere in this area. The freeze plugs look good. Nothing coming from the head. The side of the block...wait!
There, ever so faint, and normally hiding behind the starter, was the problem. A nice six inch crack in the water jacket of block. Our engine, at least the block, was junk!
Dejected, I packed up and went home. After rallying my spirits (I still hadn't told Daniel) I again turned to the Internet. I learned that there are many folks who swear by various home remedies, such as JB Weld or brazing or pinning, but nothing is certain. I briefly contemplated grinding a valley along the crack and gobbing it with JB Weld, but my better senses prevailed. We had to get another motor.

| Starting over. Looks pretty good |
Back to Craigslist. There's always at least one six cylinder for sale locally as people dump the little motors in favor of a V8. Sure enough, I immediately found a complete motor and automatic tranny in
Orlando for $300. My wife, the Wise One, knew that I'd be hitting the road early Sunday morning, and she was right. Daniel had been advised of the bad news, but I begged him not to give up hope.
The motor turned out to be out of a one-owner '67 with 85K original miles on it (supposedly). I looked it over as best I could (it was already out and hanging on a cherry picker) and asked the guy what would he take. When he replied $200, I slapped the cash in his hand. Within 10 minutes I was back on my way to Daytona. The plan was, and is, to salvage what we need, and resell the rest to recoup our costs. With some luck, we may be back whole with two weeks of lost time to show for all of this.

| All the new parts off our bad motor |
I've been poking at the motor all week, and from what little I know, it appears to indeed be a lightly used engine. The real main seal was bad, which I knew, and today we replaced it. It went in without a hitch. Right now the motor is on a stand, upside down, awaiting the oil pan to be reinstalled.
The Wise One is gone for the weekend, so Daniel and I have plenty of time to focus on the project. I told him that if he could stick with me for three or four hours each day, we should have the motor reassembled and back in the car by Sunday afternoon.

| Out with old, in with the new |
Our carb has yet to return, but should be back Monday. The rebuild shop could find nothing wrong, so we are figuring that the aftermarket fuel pump I installed might be putting out too much
pressure. To that end we'll keep the dirty old one on our "new" motor and see what happens.
If nothing else, these past few weeks certainly have been character building!
