BMW 320i Engines For Sale: Used And Reconditioned Units at Affordable Prices with Warranty

Timing Chain Stretch and Failure

Signs: Metallic rattle on cold start for 1-3 seconds, ticking at 1,500-2,000 RPM, rough idle, engine management light with cam/crank correlation codes, loss of power.
Caused by: Extended oil service intervals, low-quality oil, worn tensioners and degraded plastic chain guides - very common in UK stop-start driving.

Fully reconditioned engine fitted with upgraded timing chain kit (chains, tensioners, guides, sprockets), corrected oil feed and fresh manufacturer-spec oil. Low-mileage used units are chain-noise tested. Includes supply & fit, ECU coding and written warranty with reduced service interval advice.

EGR Valve and DPF Blockage

Signs: Loss of power, black or white smoke, frequent DPF regeneration, engine management light, limp mode, increased fuel consumption.
Caused by: Short trips preventing DPF regeneration, carbon build-up clogging EGR valve and cooler, poor fuel quality.

Reconditioned engine with decarbonised intake, cleaned or new EGR valve & cooler, DPF health check and forced regeneration, emission system reset and full road test. Supplied with diagnostics report and warranty-backed fitting.

Turbocharger and Wastegate Failure

Signs: Whistling or siren-like noise, blue smoke on acceleration, boost loss, fault code P0299, rattling on deceleration, flat power delivery.
Caused by: Oil contamination from delayed servicing, carbon deposits, heat cycles and worn wastegate actuator linkage - typically after 60k-100k miles.

Engine supplied with reconditioned or new turbocharger, upgraded oil feed pipes, new gaskets and aluminium charge pipe upgrade where factory plastic pipes fail. Includes oil system flush, boost pressure testing and warranty-backed supply & fit.

Oil Leaks from Gaskets and Seals

Signs: Burnt oil smell after parking, oil residue on engine top/sides, drips on driveway, oil in spark plug wells causing misfires, low oil warnings.
Caused by: Heat degradation of rubber gaskets, warped plastic valve covers and aged oil filter housing seals.

All reconditioned engines fitted with new OEM-spec gaskets, new valve cover if warped/cracked and resealed oil filter housing. Used engines are pressure washed, resealed and leak-tested before dispatch. Includes engine bay clean and post-fit inspection.

Cooling System Failure

Signs: Overheating, coolant warning light, heater blowing cold, coolant loss with no visible leak, cracked expansion tank.
Caused by: Electric water pump failure (common at 60k-80k miles without warning), thermostat failure and brittle plastic cooling components - a known UK weak point.

Replacement engine package includes new electric water pump, thermostat and expansion tank inspection, full cooling system pressure test and manufacturer-spec coolant bleed. Diagnostics included to prevent future overheating damage with warranty.

Carbon Build-Up on Intake Valves

Signs: Rough idle especially when cold, hesitation and throttle lag, gradual power loss, misfire codes, increased fuel consumption.
Caused by: Direct injection design - fuel never washes valves - leading to carbon deposits over 40k-60k miles, plus faulty crankcase ventilation.

Reconditioned engines include walnut blasting, reconditioned cylinder head, injector testing and new valve stem seals with improved crankcase ventilation. Fully tested before delivery with UK-wide fitting available.

High-Pressure Fuel Pump and Injector Wear

Signs: Extended cranking before start, rough idle, reduced performance under load, fuel pressure codes P0087/P0171, poor economy.
Caused by: Fuel contamination, ethanol blends, high motorway mileage and general wear of high-pressure components.

Engine supplied with tested high-pressure pump, balanced injectors, new fuel filters and calibrated fuel system. Includes live data fuel pressure checks, ECU adaptation reset and road test. Choose from used, reconditioned or rebuilt with written warranty.

Rod Bearing Wear and Crank Hub Issue

Signs: Deep knocking at low idle, low oil pressure warning, timing slip after hard driving, misfires and rough running.
Caused by: High-G cornering oil starvation, track use, tuned boost levels and oil degradation under extreme performance.

Performance-focused reconditioned build with upgraded rod bearings, measured oil clearances, reinforced crank hub solution, balanced rotating assembly and new oil pump. Built to motorsport tolerances with break-in guidance, fitting and extended warranty options.
