1960 BUICK LESABRE

Typical onset: 80,000-120,000 mi original, but many are beyond this now

Symptoms: Slipping between gears or no forward movement, Burnt transmission fluid smell, Delayed engagement when shifting to Drive, Whining or grinding noises under acceleration

Fix: Full rebuild required in most cases due to worn clutch packs, seals, and valve body components. Expect 16-24 labor hours for removal, rebuild, and reinstall. Original Dynaflow units are complex and parts availability is challenging.

Estimated cost: $2,800-4,500

Typical onset: 100,000+ mi or unknown history

Symptoms: Deep knocking sound from engine block, especially when cold, Low oil pressure at idle (under 10 psi), Metallic debris in oil or on magnetic drain plug, Progressive worsening of knock with RPM

Fix: Requires engine removal and complete teardown to replace main and rod bearings, inspect crankshaft for scoring. Often discovers worn cam bearings and rings needing attention. 35-45 hours for full lower-end overhaul including machine work.

Estimated cost: $4,500-7,500

Symptoms: White smoke from exhaust indicating coolant burning, Overheating with no external leaks visible, Coolant in oil (milky dipstick) or oil in coolant, Rough idle or misfiring on one bank

Fix: Head removal and resurfacing required. Nailhead heads are heavy and gasket surfaces often corroded. Plan 12-16 hours per side including head inspection and valve work. Heads frequently need crack checking and seat work.

Estimated cost: $1,800-3,200

Symptoms: Hard starting when cold or hot, Hesitation or stumble on acceleration, Fuel leaking from base or accelerator pump, Black smoke and poor fuel economy

Fix: Full rebuild kit with new gaskets, needle/seat, accelerator pump. Ethanol fuel degrades original components rapidly. 3-5 hours for proper rebuild including setting float levels and idle mixture. Many units have been improperly modified over the years.

Estimated cost: $350-650

Symptoms: Body sagging or misalignment, doors not closing properly, Visible rust perforation on frame rails near rear axle, Cracking or separation at body mount points, Clunking sounds over bumps from loose body

Fix: Frame inspection is critical on these cars. Surface rust is manageable, but perforation requires welding or section replacement. Body mount bushings are reproduced but installation requires body lift. 8-20 hours depending on severity, but structural frame rust can total the car.

Estimated cost: $800-3,500

Symptoms: Spongy pedal feel or pedal sinking to floor, Pulling to one side during braking, Brake fluid leaks at wheel cylinders or master cylinder, Increased stopping distances

Fix: Single-circuit drum brake system with no power assist on base models. Wheel cylinders, master cylinder, and flex hoses all degrade with age. Complete system overhaul includes all cylinders, master, hoses, and drums turned. 8-12 hours for full system refresh.

Estimated cost: $1,200-2,000

Symptoms: Ammeter showing discharge while driving, Dim lights at idle, Battery repeatedly going dead, Overcharging (over 15 volts) damaging battery

Fix: Original generator systems use external voltage regulators that fail or need adjustment. Generator brushes wear and bearings seize. Rebuilds available but many owners convert to alternator. Generator rebuild 3-4 hours, alternator conversion 4-6 hours.

Estimated cost: $400-800
