Known issues by generation
Across the generations, common issues include turbocharger stem-seal failures leading to oil-burning smoke, necessitating specialized rebuilds. The 200-4R 4-speed automatic transmissions often require stronger rebuilds to handle the power demands. Clogging of intercoolers is an issue for later intercooled models, while age-related failures such as in-tank fuel pump issues and MAF sensor wire cracking are prevalent for all. Maintaining original-paint and numbers-matching criteria enhances value significantly, making accurate diagnosis and repair essential for preservation.
