1962 DODGE POLARA

Typical onset: 80,000-150,000 mi

Symptoms: Engine rattling on cold start that quiets when warm, Intermittent backfiring through carburetor, Poor idle quality and hard starting, Check timing shows excessive retardation despite distributor adjustment

Fix: R&R timing cover, replace chain, gears, and tensioner. Requires front accessory removal, harmonic balancer puller, and setting TDC properly. Budget 6-8 hours for experienced tech, 10-12 for first-timer on these engines. Critical: inspect cam gear for wear and oil pump drive gear condition while you're in there.

Estimated cost: $800-1,400

Typical onset: 60,000-100,000 mi

Symptoms: Trans fluid puddle directly under tail housing, Fluid level drops noticeably over 500 miles, No slipping or performance issues, just leaking

Fix: Early 727s used a rear pump design that develops seal leaks. Driveshaft removal, tail housing R&R, replace seal and bushing. 3-4 hours labor. Parts availability is hit-or-miss; OEM-spec bushings are NLA from Chrysler, aftermarket quality varies wildly. Some techs convert to later non-pump tail housing if doing a full rebuild anyway.

Estimated cost: $400-650

Symptoms: Visible rust bubbles along rocker panels below doors, Soft spots in driver/passenger floor when pressed, Carpet stays damp after rain, Daylight visible through floor from underneath

Fix: Unibody Mopars of this era rust from the inside out where factory undercoating trapped moisture. Proper repair requires cutting out affected metal, welding in patch panels or full floor sections. Rockers often need complete replacement. Figure 20-40 hours depending on extent, requires frame-rail inspection for structural integrity. This is NOT a shade-tree job if you want it safe.

Estimated cost: $3,500-8,000

Symptoms: Intermittent gauge failures (especially fuel gauge), Headlights flickering or dim on one side, Dash lights working randomly, Burnt wire smell near bulkhead connector, Electrical accessories working only in certain conditions

Fix: 62-year-old cloth-wrapped wiring insulation becomes brittle and cracks, especially in engine bay heat. Bulkhead connectors corrode internally. Full harness replacement runs 12-16 hours if you rewire correctly with period-correct cloth covering. Alternatively, chase individual circuits as they fail (2-4 hours each). Many owners do piecemeal repairs until selling, which creates diagnostic nightmares.

Estimated cost: $1,200-2,800

Symptoms: Hard starting when engine is hot, Stalling at idle in traffic after highway run, Fuel smell from engine bay after shutting off hot, Engine stumbles when first pulling away after heat soak

Fix: Carter AFB and Holley 2BBL carbs sit directly over valley cover, heat-soaking after shutdown. Fuel boils in bowl, floods engine. Fix involves phenolic carburetor spacer (1" minimum), heat-shield gaskets, and sometimes rerouting fuel lines away from exhaust manifolds. Also verify mechanical fuel pump isn't cavitating. 2-3 hours to do it right with proper tuning afterward.

Estimated cost: $250-500

Symptoms: Clunking from front suspension over bumps, One side riding noticeably lower than the other, Excessive body roll in turns, Visible rust scale around torsion bar hex anchor points in lower control arms

Fix: Torsion bar anchors in lower control arms corrode and lose adjustment range or crack. Inspection requires getting under car and checking anchor hex sockets for rust expansion. If compromised, control arms need replacement (NLA from Chrysler, hunt salvage yards or aftermarket). Each side 4-5 hours, includes alignment. If you catch it early, wire-brush and treat with POR-15, but most need replacement by now.

Estimated cost: $1,200-2,000
