Everything our guides list for the variants with this engine: the engine itself plus the gearbox and ancillaries it's paired with. Each shows which cars it's listed for.

High
Coil pack failure
Individual coil-on-plug failures are the most common Falcon I6 fault. Causes misfires, rough idle, check engine light. Symptoms: lumpy idle, hesitation under load, intermittent miss. Worse in damp weather.
Fix: Replace failed coil immediately. Many owners replace the full set proactively. Use quality coils (Bosch, Delphi, Tridon) — avoid eBay generics. Inspect spark plug wells for oil contamination from valve cover seals at the same time.
From 80-150k km · ~$300-600 (set)
Listed for: Ford Falcon BA / BF · Ford Territory SX / SY / SY II / SZ
High
BTR 4-speed auto (BA only) failure
BA 4-speed auto (BTR M97) develops harsh shifts, slipping, then total failure. Most BAs need a rebuild or upgrade by 200k. Heat is the killer — towing or city driving accelerates wear.
Fix: Upgrade to ZF 6-speed conversion if budget allows ($3000+). Otherwise fluid + filter every 60k, external trans cooler mandatory. Pre-purchase, check trans oil for burnt smell.
From 100-180k km · ~$2000-4500
Listed for: Ford Falcon BA / BF
High
BTR 4-speed auto (SX/early SY)
Early BTR auto fails under SUV weight + AWD load. Slipping, harsh shifts, total failure.
Fix: Avoid pre-SY II if possible. ZF 6-speed conversion or rebuild.
From 100-180k km · ~$2000-4500
Listed for: Ford Territory SX / SY / SY II / SZ
Medium
Plenum gasket failure (later miles)
Intake plenum gaskets shrink causing vacuum leaks — rough idle, lean codes, hesitation.
Fix: Plenum gasket replacement. Upper intake removal — moderate DIY job.
From 180k+ km · ~$200-400
Listed for: Ford Falcon BA / BF
Medium
Cooling system plastic failure
Plastic thermostat housing, radiator end tanks, and overflow bottle become brittle and crack causing sudden coolant loss.
Fix: Aluminium aftermarket thermostat housing is a permanent fix. Replace radiator if end tanks weeping. Always carry coolant if running an unrebuilt cooling system.
From 120k+ km · ~$200-500
Listed for: Ford Falcon BA / BF
Medium
Plastic intake manifold runner / coolant pipe failures
The Barra uses plastic intake components and a plastic coolant crossover pipe at the rear of the head that get brittle with age and heat, cracking and causing coolant loss or vacuum leaks.
Fix: Replace with updated parts; the alloy aftermarket coolant pipe is a common preventive fix.
From 150k+ km · ~$200-700
Listed for: Ford Falcon Ute BA-FG
Medium
AWD transfer case wear
AWD-equipped Territories develop transfer case noise and wear, especially if used hard.
Fix: Transfer case rebuild. Check 4WD operation on test drive — listen for whine.
From 150k+ km · ~$1500-3500
Listed for: Ford Territory SX / SY / SY II / SZ
Medium
Front control arm ball joints
Front lower control arm ball joints wear (control arm is a one-piece replacement).
Fix: Control arm assembly replacement. Pre-purchase: jack up and check for play.
From 120k+ km · ~$400-800
Listed for: Ford Territory SX / SY / SY II / SZ
Low
Valve cover gasket weep
Valve cover gasket weeps oil onto exhaust manifold causing burning smell, sometimes contaminating spark plug wells.
Fix: Replace gasket and spark plug tube seals together. Easy DIY job — 2 hours.
From 120k+ km · ~$80-150 DIY
Listed for: Ford Falcon BA / BF
Low
Power steering pump whine and leak
PS pump bearings whine and high-pressure hose seeps. Fluid darkens.
Fix: PS pump replacement, hose if leaking. Flush system as preventive maintenance.
From 150k+ km · ~$300-600
Listed for: Ford Falcon BA / BF
Low
Cam cover and rocker cover oil leaks
The cam/rocker cover gaskets weep oil over time, sometimes onto the exhaust manifold causing a burning smell.
Fix: Reseal the cam cover; cheap DIY job.
From 120k+ km · ~$150-500
Listed for: Ford Falcon Ute BA-FG
Low
Ignition coil and coil-pack misfires
Coil-on-plug units fail with age causing misfire, rough idle and a check-engine light.
Fix: Replace coils (often as a set) and spark plugs.
