Slant Six Coolant Drain

@MeegsAp5 Oz model, driver side IS distributor side. :p IIRC you have a remote oil setup to allow the steering box to clear the spark plug side.
Do a caustic block flush with muriatic acid, and finish off with a baking soda neutralizer rinse. Its amazing what comes out with a power flush with a hose. even more amazing is when you remove the core plugs and use a high pressure washer.
