1997 MITSUBISHI PAJERO MINI

Typical onset: 80,000-120,000 mi

Symptoms: White smoke from exhaust on cold start, Coolant consumption without visible leaks, Overheating under load, Milky oil on dipstick or cap, Rough idle or misfires

Fix: Cylinder head removal, resurface the head (almost always warped on these), new gasket set, check for block deck warping. Typical 8-10 labor hours due to cramped engine bay and 4WD components in the way. Often discover lifter wear during teardown.

Estimated cost: $1,800-3,200

Typical onset: 70,000-110,000 mi

Symptoms: Loud ticking or tapping from valve cover at idle, Noise worse when cold, may quiet slightly when warm, Loss of power if valves not seating properly, Check engine light with misfire codes in severe cases

Fix: Replace all hydraulic lifters (doing one is false economy), inspect cam lobes for scoring. If cam is damaged, full camshaft R&R adds another 4-6 hours. Budget 6-8 hours for lifters alone. Use OEM or quality Japanese aftermarket—cheap lifters fail within 10k miles.

Estimated cost: $900-1,600

Typical onset: 90,000-130,000 mi

Symptoms: ATF puddles under engine bay, Transmission slipping or delayed engagement when hot, Burnt ATF smell, Hard shifts after highway driving

Fix: Replace corroded cooler lines (rubber sections crack, steel rusts at connections). If ATF has been run hot for extended periods, internal clutch damage likely. Cooler line replacement is 2-3 hours; if you're also doing a full fluid flush and filter, add another hour. Inspect transmission mount simultaneously—they collapse and cause harsh shifts.

Estimated cost: $400-800

Typical onset: 100,000+ mi

Symptoms: Severe vibration at idle, Squealing or chirping from front of engine, Visible rubber separation between inner and outer pulley sections, Check engine light with crank position sensor codes

Fix: Rubber damper separates or pulley wobbles, risking timing belt damage or crank sensor failure. Replacement is 2-3 hours (need to remove accessory belts, sometimes radiator fan for access). Do NOT ignore this—pulley failure can grenade the timing cover.

Estimated cost: $350-650

Symptoms: Hesitation or stumble under boost, Difficulty starting after sitting, Loss of power at higher RPM, Rough running that clears after a few minutes

Fix: These small turbo engines are sensitive to fuel pressure. Filter should be changed every 20-30k miles but often gets ignored. Location varies by market (some in-tank, some inline under chassis). 1 hour job for inline, 2-3 hours if in-tank. Always inspect fuel pump condition during filter service on high-mileage examples.

Estimated cost: $150-400

Typical onset: 110,000+ mi

Symptoms: Blue smoke on deceleration, Turbo whistle turns into grinding or rattling, Sudden loss of boost pressure, Oil consumption increases dramatically

Fix: Short oil change intervals critical—660cc turbo engines run hot and carbon up quickly. Failed turbos usually stem from oil starvation due to coked feed lines or owners running cheap oil. Turbo replacement is 4-6 hours; always replace oil feed and return lines, use synthetic oil moving forward. Aftermarket turbos available but quality varies wildly.

Estimated cost: $1,200-2,400
