4MG Rebuild

Sounds like the old engine was running good besides the crack so to me Now would be a good time to completely tear down and fix the cracked bare block. Rinse it out real good so you know the shavings are out. Leisurely put it back together it and put it in a truck that doesn’t have to work hard anymore. Just like @woreout said. I don’t like to see good things go to waste and I don’t like to see things scrapped that can be reasonably fixed and repurposed in other ways.

 

If Pete was to make a coe for American market today. I think you nailed it. This is what they should do. Follow the retro trend and bring back the old “bubble nose”.

 

Some of the old timers I was raised around would do something like that to keep the stat open just a little bit permanently. I know drilling a hole in one is an old trick to allow some water to bypass. Was supposed to help engine run cooler. Guys that ran from here up into the rockies would do this. This was back in the days when folks were known to remove a stat in the summer months down here in the 100 degree south. These tricks were just enough that it kept them from having to do that and they could just leave it in so it still allowed heat to build in winter.
