Addressing the issue of why one would need to change engine mounts, reminded me of a story . . .
Many years ago, while in college, I was driving my Triunph TR3a on a long, highway trip. It was very early in the morning (about one, or two) and with only about 200, or so, miles to my destination, I pulled over to the side of the highway and caught some shut-eye. When the sun came up a few hours later, I felt refreshed and excited to complete the journey. I started the TR and lit it up in an aggressive departure from my rest stop. Unfortunately, I was a bit too aggressive and the engine broke it’s engine mounts and leapt forward and inch, or so, causing the fan blades to take out the bottom two inches of the radiator. With water flowing everywhere, I immediately pulled over to take an accounting of my situation. I was literally in the middle of nowhere (rural Illinois farm country and the nearest house looked to be a mile away) and I was stuck. I had to get creative. I pulled out my tools and yanked out the radiator—-it looked pretty bad. Then, I remembered. I had a gallon can of Bondo in the trunk of the TR. I pulled it out, mixed up a big batch, and packed the lower half of the radiator with half-a gallon of Bondo. I let the unit dry for a couple of hours and put the whole thing back together and filled up the radiator with water using a discarded soda can and water from a nearby runoff trench.
I still own a TR3 (not the same one), but when I sold my first TR3a, several years later, it still had that Bondo’d radiator in it and it ran, under pressure, as cool and as leak-free as if it were the original unit. I like to look back on that incident with a feeling of accomplishment, and fondly remember it as one of my finest hours.
Thanks for letting me remember.
