After it started acting up again and I ran a leakdown test, it shot coolant out the thermostat housing showing that number three was in bad shape. Luckily I found a place that offers remanufactured heads at a reasonable price that didn’t require a core in return to get things underway quicker. Once the old head was off, I could see cracks between the valves in all four combustion chambers. (Pics to follow.)
So after the new head all is finally well, which is good because now I need to replace the leaking rusted out fuel lines on the 2 door… it’s always something.
