All AE86 Corolla problems All workshop issues

Minor Rust

Sill (Rocker Panel) Corrosion

Symptoms

The sills rust from the inside out. Paint bubbles appear on the exterior, and the metal underneath is soft or perforated.

Cause

Sills are box-section structures that trap moisture. Water enters through drain holes (if they're blocked) or through the door shuts. Once rust starts inside the sill, it's invisible until it perforates the outer skin.

Fix

Minor: cut out the rusted section and weld in repair panels.

Major: full sill replacement requiring the outer skin to be removed, the inner sill repaired or replaced, and the outer skin refitted or replaced.

Cost: $1,500-3,000 per side.

Other known issues

Minor Rust

Floor Pan Corrosion

The floor rusts from underneath, progressing from surface rust to perforation. In severe cases, you can see the road through the floor. The structural rigidity of the unibody is compromised.

Common Rust

Rear Wheel Arch Corrosion

Rust in the inner and outer rear wheel arches, often extending into the boot floor and rear quarter panel.

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

Oil Consumption

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.

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.
