2021 MITSUBISHI DELICA D:5

Typical onset: 60,000-100,000 mi

Symptoms: metallic ticking or tapping from valve cover at idle, noise increases with engine temperature, check engine light with P0300-series misfire codes, loss of power under load

Fix: Lifters collapse due to oil starvation or contamination. Requires cylinder head removal, lifter replacement (all 16 recommended, not just failed ones), cam inspection, and often valve adjustment. 12-16 hours labor. Head resurfacing adds 3-4 hours if warpage present.

Estimated cost: $3,500-6,500

Typical onset: 80,000-130,000 mi

Symptoms: rattling on cold starts that fades after 10-15 seconds, check engine light with camshaft position sensor correlation codes (P0016, P0017), rough idle, metal shavings in oil during changes

Fix: 4N14 uses a single-row chain that stretches with extended oil intervals or low-quality oil. Chain, tensioner, guides, and both VVT gears need replacement. Front cover removal required. 10-14 hours labor. Often discovered during lifter jobs.

Estimated cost: $2,800-4,200

Typical onset: 50,000-90,000 mi

Symptoms: transmission fluid pooling under vehicle, typically front-center, burnt ATF smell, low transmission fluid warnings, harsh or delayed shifts if fluid level drops

Fix: Cooler lines corrode at crimp points or crack at connections to radiator-mounted cooler. Lines are chassis-specific and often require OEM parts from Japan. 2-4 hours labor depending on access and extent of corrosion.

Estimated cost: $600-1,200

Typical onset: 70,000-110,000 mi

Symptoms: clunking when shifting from park to drive or reverse, excessive vibration at idle in gear, visible sagging or tearing of rubber mount, transmission movement visible during throttle blips

Fix: Rubber isolator degrades, especially in humid climates or with heavy loads. Mount replacement requires supporting transmission and minor exhaust work for access. 2-3 hours labor. OEM parts from Japan recommended over aftermarket.

Estimated cost: $400-700

Symptoms: loss of power and limp mode, DPF warning light or check engine light, frequent forced regeneration cycles, black smoke during acceleration, increased fuel consumption

Fix: Short trips and low-speed driving prevent passive regen. Diesel particulate filter becomes clogged. Forced regen via scan tool often works if caught early (1 hour). Severe cases need DPF removal and cleaning ($800-1,200) or replacement ($2,500+). Delete not legal in most regions.

Estimated cost: $150-3,000

Typical onset: 60,000-100,000 mi

Symptoms: rough idle when cold, hesitation under light throttle, black smoke, P0401 or P0402 codes (EGR flow insufficient/excessive), overheating in extreme cases if coolant passages clog

Fix: EGR cooler and valve accumulate carbon, restricting flow. Cleaning possible if caught early (3-4 hours), but replacement often needed due to internal passage blockage. Preventive cleaning every 40k-50k miles recommended.

Estimated cost: $800-1,800

Typical onset: 100,000-150,000 mi

Symptoms: visible wobble on crankshaft pulley during idle, serpentine belt wear or tracking issues, rough idle or vibration, pieces of rubber separating from pulley, severe cases: timing misalignment from crank sensor reading errors

Fix: Rubber isolator layer separates, causing imbalance. Requires pulley puller and reinstallation tool. 3-5 hours labor. If discovered during timing chain job, adds minimal time.

Estimated cost: $600-1,100
