Toyota 22RE Engine for Sale | OEM 2.4L EFI Inline-4 (Pickup and 4Runner)

Description

Engine Background

The Toyota 22RE is one of the most reliable inline-four engines ever built for a production vehicle. With its 2.4-liter displacement, SOHC design, and Toyota EFI system, the 22RE powered the Toyota Pickup (known internationally as the Hilux) and the Toyota 4Runner from 1983 through 1995. Many examples exceed 300,000 miles with regular maintenance; some documented examples have approached 500,000 miles. This is not marketing language: it is why the Toyota Pickup and early 4Runner became the reference vehicle for reliability in cultures from rural America to the Australian outback to conflict zones worldwide.

The 22RE distinguishes itself from the carbureted 22R by its Toyota EFI system, an L-type airflow meter-based injection setup that provides consistently accurate fuel delivery across temperature extremes, altitude changes, and load variations. For off-road use in particular, the EFI’s consistent operation regardless of vehicle angle gives the 22RE a significant advantage over the 22R’s carburetor, which can flood or starve on steep grades.

The critical piece of information every 22RE buyer needs to know: Toyota significantly redesigned the 22RE in 1985. The post-1985 block has a different deck height. The cylinder head, pistons, timing components, water pump, and oil pump changed. Pre-1985 and post-1985 parts are largely not interchangeable. Installing a pre-1985 head on a post-1985 block (or vice versa) will cause severe compression problems and potential engine damage. We confirm block generation before every order ships. Call (240) 306-7051 to verify pre-1985 vs post-1985 availability for your truck.

When Replacement Becomes Necessary

• Coolant loss without visible external leak, head gasket failure (the most common major 22RE failure). Check the oil for a milky appearance or the coolant for oiliness.
• Blue smoke under hard acceleration, valve stem seal wear or piston ring wear on high-mileage units
• Hard cold start or rough cold idle that resolves after warmup, EFI cold start system issue, airflow meter failure, or coolant temperature sensor fault
• Oil burning on all conditions not just cold start, ring and cylinder wall wear on high-mileage engines
• Timing chain rattle on cold start that persists after warmup, timing chain tensioner or guide wear
• Fuel delivery hesitation under load, clogged injectors or failing airflow meter

Known Issues We Document Before Shipping

• Head gasket failure, the 22RE’s primary weakness: despite legendary reliability overall, the 22RE aluminum head gasket is the engine’s Achilles heel. Overheating at any point in the engine’s life compromises the head gasket. We compression test all 4 cylinders and inspect coolant for contamination before shipping. Any unit showing signs of head gasket failure is rejected.
• Pre-1985 versus post-1985 block incompatibility: this is the most common installation mistake. In 1985, Toyota changed the cylinder head, block deck height, timing system, and pump configurations. Parts from the two generations do not interchange. If you are replacing a post-1985 22RE with a pre-1985 unit (or vice versa), all associated cooling system and timing components must match the new engine’s generation. We document block generation on every unit.
• Timing chain wear: the 22RE uses a timing chain (not a belt), which is reliable but does wear on high-mileage units. Timing chain rattle on cold start is the primary indicator. We inspect timing chain noise where accessible during pre-ship inspection.
• Carburetor versus EFI: the 22R is carbureted; the 22RE is fuel-injected. Block architecture is similar but heads, intakes, and fuel systems differ significantly. We confirm 22RE (EFI) versus 22R (carb) on every order.
• Mass airflow sensor wear: the 22RE’s L-type airflow meter contains a moving vane that wears on high-mileage units. Symptoms include rough idle and poor cold start. The sensor is serviceable separately from the engine.

Used OEM Versus Specialist Rebuild

For a Toyota Pickup, Hilux, or 4Runner restoration or replacement, a documented used 22RE with head gasket condition assessed and block generation confirmed is the cost-effective path given the engine’s inherent durability. For a high-mileage donor or an off-road expedition build, a specialist rebuild with refreshed head, new head gasket, fresh timing chain, and updated water and oil pumps is the better long-term investment. Specialist 22RE rebuilds typically run $3,000 to $5,000 from established Toyota truck shops.

Inspection Workflow

• Compression test logged across all 4 cylinders with uniformity reported
• Block generation confirmed: pre-1985 or post-1985
• Fuel system identified: 22RE (EFI) or 22R (carb)
• Head gasket condition assessed via coolant cross-contamination check
• Timing chain noise evaluated at cold start where accessible
• Mass airflow meter condition externally inspected
• External oil leak survey at front cam seal, valve cover, oil pan, distributor o-ring

Pre-Purchase Buyer Notes

• Confirm block generation before ordering: pre-1985 22RE parts are not interchangeable with post-1985 parts. Mixing generations causes severe problems. Verify your donor truck year and match the generation accordingly.
• Plan a head gasket service at install: the 22RE head gasket is the engine’s known weak point. Inexpensive insurance against post-install overheating. Use Toyota OEM or equivalent multi-layer steel gasket.
• Refresh the timing chain on high-mileage units: timing chain wear is a known issue. Replacing the chain, tensioner, and guides while the engine is out is straightforward and cheap insurance.
• Inspect the mass airflow meter: a worn airflow meter causes rough idle and poor cold start. The component is serviceable separately and inexpensive to replace if needed.
• Source supporting parts in advance: 22RE parts are widely available (one of the engine’s advantages) but specific items like cold start injectors, distributor caps, and airflow meters are easier to source as a complete refresh package.
