1999 CHEVROLET METRO

Typical onset: 80,000-140,000 mi

Symptoms: White smoke from exhaust, especially on cold starts, Coolant loss with no visible leaks, Overheating under load or in traffic, Milky oil on dipstick or oil cap, Rough idle and misfires when head warps

Fix: Requires cylinder head removal, resurfacing (often warped .008-.015 inches), new head gasket set, and timing belt replacement while apart. Budget 8-12 labor hours. High failure rate due to thin gasket design and aluminum head movement on cast iron block. Many shops recommend ARP head studs over OEM bolts for longevity.

Estimated cost: $1,200-2,000

Typical onset: 100,000-150,000 mi

Symptoms: Severe vibration at idle that smooths out at higher RPM, Visible wobble on harmonic balancer, Front main seal leaking oil, Metallic knocking from front of engine, Check engine light with crank position sensor codes

Fix: The three-cylinder is inherently unbalanced and the harmonic balancer rubber deteriorates, leading to crank snout wear and eventual nose breakage. Harmonic balancer replacement alone is 2-3 hours, but if crank nose is damaged, you're looking at full engine teardown or replacement. Some techs report finding metal shavings in oil pan from keyway wear.

Estimated cost: $300-600 (balancer only), $2,500-4,000 (if crank damage requires rebuild)

Typical onset: 60,000-100,000 mi

Symptoms: Severe clunking when shifting from reverse to drive, Excessive engine movement visible under hood during acceleration, Vibration through shifter and steering wheel, Difficulty engaging gears on manual transmission, Accelerated CV axle and transmission seal wear

Fix: The rubber mounts are undersized for the vehicle and deteriorate quickly, especially the rear transmission mount. When mounts fail, drivetrain movement causes the transmission to shift position, stressing axles and cooler lines. Replace all three mounts simultaneously (2-3 hours labor). Ignoring this accelerates transmission oil cooler line failures and axle boot tears.

Estimated cost: $250-450

Typical onset: 70,000-110,000 mi

Symptoms: Slipping under acceleration, especially in higher gears, Clutch chatter on engagement, Hard pedal effort or pedal staying to floor, Difficulty shifting, grinding into gears, Burning smell during normal driving

Fix: The lightweight flywheel develops heat checking and grooves quickly with aggressive driving. Many techs find flywheel needs resurfacing or replacement when doing clutch jobs. Always replace pilot bearing and inspect transmission input shaft seal. Budget 5-7 hours labor. The hydraulic clutch system rarely fails, but cable-adjusted early models need periodic adjustment.

Estimated cost: $600-1,000

Typical onset: 90,000-130,000 mi

Symptoms: Transmission fluid puddles under front of vehicle, Pink or red fluid dripping near radiator, Low transmission fluid warnings or slipping, Delayed engagement after sitting, Transmission overheating

Fix: Steel cooler lines rust through where they pass under the engine, accelerated by road salt and failed engine mounts causing vibration wear. Lines are cheap but access requires removing intake components or working from underneath. 2-3 hours labor. Often discovered too late after transmission has run low on fluid and suffered internal damage.

Estimated cost: $200-400 (lines only), $1,500-2,500 (if internal transmission damage)

Typical onset: 60,000-mile intervals, catastrophic if neglected to 80,000+

Symptoms: Sudden no-start with cranking but no compression, Coolant leak from water pump weep hole, Squealing or chirping from timing cover area, Engine runs rough after belt jumps timing, Bent valves after belt failure (interference engine)

Fix: This is an interference engine — belt failure means valve-to-piston contact and cylinder head work. Timing belt service should include water pump, tensioner, and all seals (5-6 hours labor). Many used Metros have unknown maintenance history; if belt age is uncertain, replace immediately. Camshaft R&R and head work after failure runs 12-16 hours total.

Estimated cost: $400-700 (preventive service), $1,800-3,000 (after failure with valve damage)
