1995 MITSUBISHI PAJERO MINI

Typical onset: 80,000-120,000 mi

Symptoms: White smoke from exhaust on startup, Coolant loss with no visible leaks, Overheating under load, Milky oil on dipstick or filler cap, Rough idle when cold

Fix: The 4A30T head gasket fails due to inadequate cooling design and turbocharged stress on a tiny motor. Head must come off, get resurfaced (almost always warped 0.008-0.015 inches), new gasket set, and timing belt replacement while you're in there. Budget 12-16 hours labor. Use OEM gaskets—aftermarket units fail quickly.

Estimated cost: $1,800-2,800

Typical onset: 60,000-100,000 mi

Symptoms: Ticking or tapping from valve cover, worse when cold, Loss of power on acceleration, Check engine light with misfire codes, Noise disappears after 5-10 minutes of warm-up initially, then becomes constant

Fix: The hydraulic lifters collapse due to tiny oil passages clogging from infrequent changes or low-quality oil. All 12 lifters should be replaced together (not individually) along with camshaft inspection for scoring. If cam lobes are damaged, add another $600-900 for camshaft R&R. Total 8-10 hours labor if lifters only.

Estimated cost: $1,200-1,600

Typical onset: 70,000-110,000 mi

Symptoms: ATF puddles under front of vehicle, Transmission slipping or delayed engagement when hot, Burnt ATF smell, Overheating transmission temp gauge (if equipped), Pink milky ATF indicating coolant contamination

Fix: The rubber lines from transmission to the small front-mounted cooler crack and leak. Worse: the cooler itself corrodes internally and can cross-contaminate ATF with coolant, killing the transmission in 500 miles. Replace cooler, all lines, flush transmission completely, and monitor closely. If coolant got into trans, you're looking at a rebuild or replacement. 4-6 hours labor for cooler and lines only.

Estimated cost: $800-1,400

Typical onset: 90,000-130,000 mi

Symptoms: Vibration at idle that worsens with RPM, Serpentine belt shredding or coming off repeatedly, Visible wobble on crankshaft pulley, Rough running despite good tune-up, Timing marks no longer align correctly

Fix: The rubber bonding layer in the harmonic balancer separates, letting the outer ring slip. This throws off timing marks and can destroy your crankshaft nose if the pulley wobbles loose. Replacement requires removing the radiator for access on this tight engine bay. 3-4 hours labor. Don't ignore belt issues—they're often this, not tensioner.

Estimated cost: $450-700

Symptoms: Blue smoke on acceleration, Turbo whine or whistle changes pitch, Loss of boost pressure, Oil consumption increases noticeably, Turbo lag becomes severe

Fix: The tiny oil feed line to the turbo restricts from sludge buildup if oil changes were skipped. Starved turbo bearing fails, dumping oil into exhaust. Clean or replace feed line, inspect turbo for shaft play—if more than 1mm radial movement, turbo needs rebuild or replacement. 5-7 hours labor for turbo R&R. Preventable with 3,000-mile synthetic oil changes.

Estimated cost: $900-1,800

Typical onset: 80,000-120,000 mi

Symptoms: Clunk when shifting from Park to Drive, Excessive vibration at idle in gear, Transmission feels like it's moving under hard acceleration, Grinding or rubbing noise from bellhousing area

Fix: The rubber transmission mount deteriorates and lets the trans sag, causing driveline vibrations and potentially damaging shift linkage. Easy 2-hour job but requires supporting the transmission. OEM mounts last 50,000 miles; aftermarket polyurethane versions add NVH but last longer.

Estimated cost: $250-400
