It was good seeing you too, Bob. Remember I pointed out to you one of the freeze plugs that looked like it was leaking? Well, after I left your place, I decided to take a spin to Hesperia and see a girl I know. The car seemed to be doing okay when I started up Cajon Pass, driving on the old Route 66 down below the 15 freeway. As I got pass the 138, the engine was bogging down in 3rd/overdrive, so I pulled over, stopped, pulled the O/D cable to disengage it and started back out (Mind you, this is where that steep part of the climb starts). It seemed to be taking off pretty well and also had a little more power, but the engine was really racing in 3rd at 50mph. I got about two miles and started smelling anti-freeze. I looked at my temp gauge and it was at about 170. So, I pulled over off the freeway at a turnout and then the gauge started to move up quickly so I shut off the engine. Got out and opened the hood and there was steam coming out from the bottom side of the engine. Yep! The freeze plug that was in question had popped out. After saying a few unmentionables, I started walking to the call box to call AAA because I didn't have my cell phone on me. As I was walking to the call box, a semi pulled over and it turned out to be a former student of mine from about 10 years back. He let me use his cell phone to call a tow truck and then we chatted and I showed him the car while I waited. Within 25 minutes, the the flatbed was there and probably one of the best tow truck drivers I had ever delt with. This guy had total respect for the car and went to great lengths to make sure he didn't scratch any of the chrome by wrapping the chains with rags and duct tape and raising it on to the flatbed carefully. When we got to the mechanic, I gave him a $20 tip for taking extra care.
When John, the mechanic, saw me drive ride up in the tow truck with the car on the back, he hung his head. He felt so bad that he reimbursed me for the tip I gave the driver. He said that he couldn't understand why they were popping out because the cooling system isn't pressurized. I remembered that I have a 9 lb pressure radiator cap on there and was curious if that caused pressure. He said that it could be, but he doubted it. Nonetheless, he will look into it.
Anyway, the car is back in shop and John is looking for better freeze plugs...the kind that you can tighten and they expand. I think the one the popped out was steel or brass. Apart from the freeze plugs popping out, the car runs and handles beautifully like you said.
