1997 CHEVROLET METRO

Typical onset: 80,000-140,000 mi

Symptoms: White smoke from exhaust, especially on cold start, Coolant loss with no visible leaks, Overheating or running hot, Milky oil on dipstick or oil cap, Rough idle or misfires after warm-up

Fix: Requires cylinder head removal, resurfacing (usually warped 0.005-0.015 inch), new head gasket set, timing belt replacement while apart, and coolant flush. Budget 8-12 hours labor. The 1.0L three-cylinder is far more reliable and rarely sees this issue. Head bolts must be torqued in proper sequence with angle gauge to prevent repeat failure.

Estimated cost: $800-1,400

Typical onset: 100,000-150,000 mi

Symptoms: Visible rubber separation between inner hub and outer ring, Vibration at idle that worsens with RPM, Serpentine belt tracking off-center or shredding, Squealing or chirping from front of engine

Fix: The rubber isolator deteriorates and delaminates, causing the outer pulley ring to wobble. Replacement requires special puller and installer tools; budget 2-3 hours. If it grenades, it can take out the serpentine belt and leave you stranded. Inspect every oil change after 90K miles.

Estimated cost: $200-350

Typical onset: 120,000-180,000 mi

Symptoms: Grinding or crunching when shifting into second gear, Difficulty engaging second, especially when cold, Gear pop-out under load in second, Whining noise in second gear

Fix: Second gear synchro wears first on these five-speeds, especially if driven hard or shifted quickly. Transmission rebuild requires 6-8 hours labor; many shops opt for used transmission swap (4-5 hours) given the car's value. Clutch replacement recommended while trans is out, adding 1 hour and $150-250 in parts.

Estimated cost: $600-1,200

Typical onset: 80,000-130,000 mi

Symptoms: Clunking when shifting or engaging clutch, Excessive engine movement visible during acceleration, Vibration through shifter or floorboard, Difficulty engaging gears

Fix: The rear transmission mount (hydraulic type) collapses internally, allowing excessive drivetrain movement. Simple replacement takes 1-1.5 hours; access is straightforward from underneath. Inspect all three engine/trans mounts simultaneously. This is a wear item that should be addressed before it damages shift linkage.

Estimated cost: $150-280

Symptoms: Hard starting after sitting overnight, Sputtering or hesitation under load, Stalling at highway speeds, Poor acceleration, feels like fuel starvation, Won't start when tank is below 1/4

Fix: Metros are prone to internal tank rust if not driven regularly or if moisture accumulates. Rust particles clog the in-tank fuel strainer and inline filter. Filter replacement is 0.5 hour job, but if tank is heavily contaminated, requires drop and clean (2-3 hours) or replacement. Consider fuel system cleaner and keep tank above half to minimize issue.

Estimated cost: $80-150 (filter only), $400-650 (tank service)

Typical onset: 180,000+ mi

Symptoms: Ticking or tapping noise from valve cover that worsens with RPM, Loss of power and poor fuel economy, Check engine light with multiple misfire codes, Low oil pressure at idle

Fix: Inadequate oil changes or running low on oil wears cam lobes and followers. Requires head removal, cam replacement, valve job, and new lifters; essentially a 12-15 hour top-end rebuild. At this point, many owners opt for used engine swap (8-10 hours) or scrap the car. Preventable with religious 3,000-mile oil changes using quality oil.

Estimated cost: $1,200-2,000
