A relative offered to give me some old farm equipment that they no longer used, so I decided to make a round trip there in my Subaru Sambar truck, also to say hello after a long time.
The round trip was about 2,600 km.
However, about halfway through the trip, about 600 km in, the engine started to malfunction.
For some reason, it wouldn’t idle steadily.
Still, I managed to get by and accomplished my goal of visiting my relatives, but on the way back, after driving about 1,400 km, the engine was running at its worst.
As I didn’t have any tools, I found a dealership’s repair shop and had them take a look, and they told me that the spark plug on cylinder 2 had melted and wouldn’t be an easy fix.
I decided to load the entire light truck with my luggage into a rental pickup truck and head home.

The dimensions of the 2-ton truck’s bed were just barely big enough to fit a Subaru Sambar truck on.
I came back carefully, worried that it would be terrible if I dropped it on the way there.
It was a very tight squeeze both when loading and unloading.
When I was loading it, the engine had lost power and I couldn’t get it onto the bed on my own, so I used the downhill slope to gain momentum and somehow managed to get it on.
When I got back, the engine wouldn’t start and I had to use the slope of the hill again to get it down, so it really was a tight squeeze.

When I got home and looked at the plugs, I found that they had indeed melted.
And not just plug number 2, but plug number 3 too!
Maybe because I had been driving around in a false sense of security, the damage had spread to plug number 3 as well.

Numbers 1 and 4 seemed to be fine.
I wonder what was different…

When I measured the compression, numbers 2 and 3 were zero, so I wonder what’s going on inside…
It’s scary just to imagine it.
I’ll talk about the repairs at a later date…
