The first V6 used in the Chrysler minivans was the Mitsubishi 3.0, noted for high oil consumption. I think the 3.0 was introduced for the 1987 model year.That’s a good looking van! Didn’t the 3.3 tend to fail head gaskets or consume oil or something?
I remember the hunter green town and country with OE gold accent wheels was the go to van in the mid 90s.
The in-house 3.3 replaced the 3.0 around 1990, and was a much better engine. I don't think it had any glaring weaknesses. It and its big brother, the 3.8 were used in the Dodge and Chrysler minivans until around 2010, finally succeeded by the 3.6. Pentastar.
