Ford Ranger 2.3 Engine for Sale | OEM Lima OHC Inline-4 (1983 to 1997)

Description

Engine Background

The Ford Ranger 2.3 Lima OHC engine is one of the most long-lived four-cylinder engines in American truck history. Introduced in the Ranger for 1983, it traces its roots directly to the German-designed 2.0-liter EAO engine that powered European Ford Cortinas and US-market Mercury Capris in the early 1970s. Ford expanded it to 2.3 liters for the 1974 Pinto and carried the architecture into the compact truck lineup, where it remained the standard four-cylinder in the Ranger until 1997, a 14-year run in the Ranger alone.

The Lima 2.3 went through three significant evolution phases in the Ranger. The early carbureted versions from 1983 to 1988 used a flat-tappet camshaft, a two-piece rope rear main seal (pre-1986), and a Duraspark distributor. The 1988 model year introduced a hydraulic roller camshaft, a significant improvement in durability and reduced oil consumption, along with smaller-diameter crankshaft main journals. The 1989 model year introduced the most distinctive version: a distributorless ignition system with dual spark plugs (two plugs per cylinder, eight total), multi-point EFI, and a revised cylinder head. This DIS version produced 105 hp versus the early carbureted unit’s 82 hp.

The Lima 2.3 also powered the Bronco II, the Fox Body Mustang (both the turbocharged SVO version and the naturally aspirated base), and various Ford Mustang applications from 1979 through 1993. The Ranger application is specifically the naturally aspirated version; the turbocharged variants found in Mustang SVO and Thunderbird Turbo Coupe were never installed in the Ranger.

When Replacement Becomes Necessary

• Oil burning on cold start, valve stem seal wear on high-mileage Lima OHC heads
• Rough idle on DIS engines that does not respond to basic tune, DIS module or crankshaft position sensor fault
• Rear main seal oil leak, pre-1986 two-piece rope seal is a known chronic seep on aged engines
• Timing belt noise or vibration, the Lima 2.3 uses a TIMING BELT, not a chain. The belt must be replaced every 60,000 miles. A failed timing belt causes catastrophic engine damage on this interference engine.
• Loss of compression on one or more cylinders, ring wear or valve seal failure on high-mileage units
• Spark plug fouling on DIS engines: dual plugs per cylinder means 8 plugs total. One fouled plug on a cylinder causes misfire that can be misdiagnosed.

Known Issues We Document Before Shipping

• Timing belt, the most important Ranger 2.3 service item: the Lima 2.3 uses a rubber timing belt (not a chain) driving the SOHC camshaft. It MUST be replaced every 60,000 miles. A broken timing belt causes complete valve-to-piston contact on this interference engine and destroys the head. We inspect the timing belt condition and note age indicators before shipping, but always replace it at installation regardless.
• DIS versus pre-DIS incompatibility: a 1989-and-newer DIS engine cannot simply replace a pre-DIS carbureted engine without converting the complete ignition and fuel system. The DIS engine uses 8 spark plugs and a completely different ECU, wiring harness, and EFI fuel system from the pre-1989 carbureted versions. We document the ignition system on every order.
• Roller versus flat-tappet cam: pre-1988 Lima engines used flat-tappet cams. 1988-and-newer engines use hydraulic roller lifters. Lifters and cam are different between the two; mixing components causes failure. The 1988 transition also reduced crankshaft main journal diameter, which affects bearing selection. We confirm cam type on every unit.
• Two-piece versus one-piece rear main seal: pre-1986 Lima engines use a two-piece rope rear main seal that seeps chronically on aged engines. 1986-and-newer engines use a one-piece neoprene rear main seal that is dramatically more reliable. If converting an older Ranger, this is one of the few good arguments for sourcing a 1986-or-newer unit.
• Head gasket on overheated engines: the Lima 2.3 aluminum head is sensitive to overheating. Any engine that has been run hot is at risk. We compression test all 4 cylinders and check coolant for cross-contamination before shipping.

Used OEM Versus Specialist Rebuild

For a Ranger replacement on a reasonable budget, a documented used Lima 2.3 with year and variant confirmed is the cost-effective path. The engine’s simplicity and parts availability make rebuilds easy if you choose that route. Specialist Lima 2.3 rebuilds typically run $2,500 to $4,000 from established Ford specialist shops, plus the supporting items (timing belt, water pump, harness if converting between generations). Used OEM is typically the right choice for this engine given the cost-to-benefit ratio.

Inspection Workflow

• Compression test logged across all 4 cylinders with uniformity reported
• DIS versus pre-DIS ignition system documented
• Cam type identified: roller (1988 onward) or flat-tappet (pre-1988)
• Rear main seal generation noted: one-piece (1986 onward) or two-piece (pre-1986)
• Fuel system identified: carburetor, TBI, or multi-port EFI
• Timing belt condition assessed with age indicators noted
• Head gasket condition assessed via coolant cross-contamination check
• External oil leak survey at front cam seal, valve cover, oil pan, rear main

Pre-Purchase Buyer Notes

• Replace the timing belt at installation regardless of donor service history: this is non-negotiable on the Lima 2.3. A failed belt destroys the head. Belts age in storage even unused. Always install fresh belt, water pump, and tensioner.
• Match ignition system to your chassis: a DIS engine in a pre-DIS chassis requires complete ignition and fuel system conversion (ECU, harness, fuel injection, 8-plug head, etc.). For pre-DIS chassis, source a pre-DIS engine. For DIS chassis, source a DIS engine.
• Match cam type to lifters: roller lifters do not work on flat-tappet cams (and vice versa). Mixing components causes immediate failure. We document cam type on every unit.
• Plan for rear main seal upgrade on pre-1986 engines: the two-piece rope seal is a chronic leak source. If sourcing a pre-1986 engine, plan a one-piece conversion at installation. Aftermarket conversion kits are available.
• Use ZDDP on flat-tappet cams: pre-1988 engines require high-zinc oil. Modern low-zinc oils accelerate cam lobe wear.

Why Buy From Part Nests

• Rear main seal generation noted: one-piece (1986+) or two-piece (pre-1986)
• Fuel system documented: carburetor, TBI, or EFI
