Common Engine, 4A-GE 1.6L DOHC Inline-4

Oil Consumption

Symptoms

Blue smoke on overrun (deceleration after high RPM) or under hard acceleration. Oil level drops between services. Fouled spark plugs, particularly on cylinders 1 and 4.

Cause

The 4A-GE uses small-diameter pistons and rings that are sensitive to wear. Years of high-RPM driving (which is how you're supposed to drive a 4A-GE) accelerates ring and bore wear. Valve stem seals harden with age and allow oil past the guides, particularly on the exhaust side.

Fix

Valve stem seal replacement is possible with the head in situ (using compressed air to hold the valves up), cost: $300-600.

If ring wear is the cause, a full engine rebuild is required: hone the block, new rings, valve stem seals, bearings, and gaskets.

Cost: $2,000-4,000 for a full rebuild.

A litre per 3,000 km is liveable; more than that warrants attention.

Other known issues

Minor Engine, 4A-GE 1.6L DOHC Inline-4

Timing Belt Failure

The engine stops instantly. On the 4A-GE (interference engine), the pistons hit the valves, bending the valves and potentially cracking pistons and damaging the head.

Common Engine, 4A-GE 1.6L DOHC Inline-4

T-VIS Failure

Loss of top-end power. The engine feels flat above 4,500 rpm and doesn't pull strongly to the redline. No audible "click" from the T-VIS actuator around 4,200 rpm.

Minor Engine, 4A-GE 1.6L DOHC Inline-4

Distributor O-Ring Oil Leak

Oil leaking from the base of the distributor, running down the side of the engine. Oil contamination on the distributor cap and leads.

Common Gearbox, T50 5-Speed Manual

Synchro Wear (2nd and 3rd Gear)

Crunching or grinding when shifting into second or third gear, particularly on fast downshifts. The synchro ring can no longer match shaft speeds, and the gear teeth clash.

Common Gearbox, T50 5-Speed Manual

Gearbox Mount Failure

Excessive vibration through the gearstick, clunking during gear changes, and the gearstick feeling loose or imprecise.

Common Differential

Diff Noise and Whine

Whining noise from the rear axle that changes pitch with speed. Clunking on acceleration or deceleration.
