Bringing a Seized 1970 Oldsmobile 98 Back to Life After 30 Years

Rescuing a Barn Find

• 🚗 A 1970 Oldsmobile 98 was purchased for $800, having sat abandoned in a barn for approximately 30 years.
• 🔑 The car was missing its keys, and the tires were flat, presenting immediate challenges to moving it.
• ✨ Despite its long dormancy, the interior was found to be in remarkably good shape, with intact seats and minimal wear.

Mechanical Revival and Brake Restoration

• 🛠️ The team tackled seized drum brakes, replacing wheel cylinders and hoses, and resurfacing the drums.
• 💨 The car's unique speedometer cable setup, driven off the dust cap on the spindle, was noted.
• 💧 The fuel tank was replaced due to a significant leak, with a 1968 Impala tank from Tanks Inc. being adapted for fitment.

Engine and Drivetrain Challenges

• ⚙️ The 455 cubic inch engine was found to be seized, requiring ATF fluid soak to free up the pistons and rings.
• 🔥 Initial attempts to start the engine revealed issues with compression in several cylinders, possibly due to carbon buildup or sticky valves.
• 💡 After extensive work, including cleaning and replacing ignition points, the engine eventually started and ran, albeit with some initial roughness and a persistent issue with one cylinder.

Bringing the Oldsmobile Back to the Road

• 🌟 New tires and wheels were installed, significantly improving the car's appearance and readiness for driving.
• 🔧 Steering and alignment issues were addressed, including straightening a bent tie rod and replacing a rusted transmission cooler line.
• ✅ The car was ultimately brought back to life, running and driving, with functional brakes and a quiet, smooth ride, despite some remaining cosmetic and minor mechanical issues.
