18 -20 FORD F150 F-150 5.0 COYOTE ENGINE MOTOR CORE FOR PARTS OR REBUILD
2018–2020 Ford F-150 5.0L Coyote (Gen 3) as a “core” for parts or a rebuild, there are several critical technical factors that separate a high-value core from a “scrap” block.
Core Identification & Specs
The 2018–2020 F-150 engine is the Gen 3 Coyote. While it shares the same 5.0L displacement as the Mustang, it features different camshafts and a lower compression ratio ($12.0:1$) optimized for truck torque curves.
-
Block Material: Aluminum with Plasma Wire Arc Liner (PTWA). Note: This liner makes traditional over-boring difficult; most rebuilds require sleeving if the cylinder walls are scored.
-
Fueling: Dual Injection (Direct and Port).
-
Oil Capacity: 8.8 Quarts (5W-20 or 5W-30).
Rebuild & Parts Value Assessment
If you are evaluating this motor as a “Core,” focus on these high-value components:
| Component | Value/Condition Check |
| Cylinder Heads | Check for warped surfaces or cracked seats. Gen 3 heads are highly desirable for porting. |
| Crankshaft | Forged steel (standard in Gen 3). Ensure the snout and journals aren’t heat-discolored. |
| Cams/Phasers | Variable Cam Timing (VCT) solenoids and phasers are common failure points; if functional, they add significant value. |
| Engine Block | Inspect for “windowing” (rods through the side). Even a damaged block has value as a “mock-up” tool for custom builds. |
Critical Technical Watch-Points
For the 2018–2020 model years, there are two specific issues that often lead to these engines becoming cores:
-
Oil Consumption: Many 2018–2019 units were flagged for excessive oil consumption due to PCV issues or ring seating. A “core” from this era may need a specific ring/hone strategy during the rebuild.
-
Timing Chain Guides: Plastic guides can wear down or shatter at higher mileages ($100k+$), causing timing jumps.
