What is the 1990-1999 Mitsubishi Eclipse Balance Shaft Belt Failure Destroying the Timing Belt (Interference 4G63)?

The turbo 4G63 is an interference engine, and its narrow balance shaft belt runs directly alongside the main timing belt. When the aging balance shaft belt frays or snaps — common on neglected 1G six-bolt and 2G seven-bolt cars — the debris gets caught in the timing belt, causing… Repairs typically run $1,500-$4,000. Severity: high.

What is the 1990-1998 Mitsubishi Eclipse AWD Transfer Case Lockup and Output Shaft Seal Leaks (GSX, NHTSA Recall 98V069001)?

On AWD GSX (and Talon TSi AWD platform) cars, the transfer case output shaft seal leaks gear oil until the case runs dry, and per NHTSA recall 98V069001 'lockup of the transfer case can occur due to insufficient lubrication.' Owners have reported the wheels locking at 50-68 mph,… Repairs typically run $300-$2,000. Severity: high.

What is the 1995-1998 Mitsubishi Eclipse Front Lower Ball Joint Boot Damage and Separation (NHTSA Recalls 99V066001 / 00V421001)?

Mitsubishi issued two recalls (99V066001, then the expanded 00V421001) on 2G Eclipses because the rubber boots on the front lower lateral arm ball joints were damaged during assembly, letting dirt and water into the joint. A worn, contaminated ball joint can separate from the knu… Repairs typically run $150-$500. Severity: high.

What is the 1990-1998 Mitsubishi Eclipse AWD (GSX) Transfer Case Lockup - NHTSA Recall 98V069000?

The all-wheel-drive Eclipse GSX was recalled (NHTSA campaign 98V069, March 1998) covering 1990-1998 GSX models. A brass plug in the center of the transfer case yoke can leak, causing insufficient lubrication in the transfer case; the transfer case can then lock up, which can caus… Repairs typically run $800-$2,500. Severity: high.

What is the 1990-1999 Mitsubishi Eclipse Front Subframe / Crossmember and Rocker Rust Corrosion (salt-belt cars)?

Like most DSM-era cars, 1990s Eclipses in road-salt regions suffer structural corrosion of the front crossmember/subframe (which locates the lower control arms) as well as the rocker panels, strut towers, and rear subframe/trailing-arm mounts. Because the lower control arms bolt… Repairs typically run $500-$2,500. Severity: high.

What is the 1990-1999 Mitsubishi Eclipse Timing Belt Failure on Interference 4G63 (catastrophic valve damage)?

The DOHC 4G63 (both the naturally aspirated 4G63 and turbo 4G63T across 1990-1999) is an interference engine: if the timing belt snaps or jumps, the pistons strike the open valves, bending valves and often damaging the head and pistons. These belts were specified for replacement… Repairs typically run $600-$3,500. Severity: high.

What is the 1990-1999 Mitsubishi Eclipse Rust at Rear Wheel Arches, Lower Quarter Panels, and Rockers?

Both 1G and 2G Eclipse/Talon bodies rot in predictable places: the rear wheel arches and the lower quarter panel just ahead of the rear tires, the rocker/support area under the doors, and — most structurally serious — the front strut towers. The arch and rocker seams trap road sa… Repairs typically run $500-$3,000. Severity: medium.

What is the 1995-1999 Mitsubishi Eclipse 2G Fuel Pump Wiring Voltage Drop and Fuel Pump/MFI Relay Failure?

On 1995-1999 cars the fuel pump's factory wiring is undersized and its chassis ground (at the floor crossmember under the driver's seat) corrodes with age, dropping voltage at the pump into the 10-11V range under load. The paired fuel pump/MFI relay behind the center console can… Repairs typically run $75-$400. Severity: medium.

What is the 1990-1999 Mitsubishi Eclipse Cam Angle Sensor (CAS) / Optical Distributor Failure - No-Start and Stalling?

The 4G63 uses a cam angle sensor (an optical sensor mounted in the distributor housing on the exhaust cam) to provide the crank/cam timing signal to the ECU. With age the CAS optical disc, LEDs/phototransistors, and internal bearing wear out and produce erratic or lost signals. O… Repairs typically run $200-$550. Severity: medium.

What is the 1990-1999 Mitsubishi Eclipse Lifter Tick from Hydraulic Lash Adjusters?

The 4G63's hydraulic lash adjusters (lifters) are notorious for clogging with oil varnish or bleeding down, producing the infamous DSM 'lifter tick' from the valve cover. The early-design lifters used in 1G cars were revised twice by Mitsubishi specifically to address the noise. Repairs typically run $150-$900. Severity: low.

What is the 1990-1999 Mitsubishi Eclipse Valve Stem Seals Hardening - Oil Consumption and Blue Smoke at Idle?

As the 4G63/4G63T ages, the valve stem seals harden and shrink, letting oil seep down the valve guides into the combustion chamber. The signature symptom is a puff of blue smoke on startup or on a quick rev after the engine has idled for a while, plus gradual oil consumption. Tur… Repairs typically run $400-$1,200. Severity: low.

What is the 1995-1999 Mitsubishi Eclipse 4G63 7-Bolt Crank Walk (Thrust Bearing Failure)?

The 1995-1999 Eclipse GS-T and GSX use the 7-bolt 4G63 turbo engine, which is notoriously prone to 'crank walk' — excessive axial movement of the crankshaft caused by thrust bearing failure. The crankshaft literally moves fore-and-aft inside the block, eventually destroying the c… Repairs typically run $3,500-$7,500. Severity: high.
