Michael Pasko purchased two Ford F-150s and sold both within a few years. The Chicago owner said the trucks had identical mechanical problems—cam phaser failures, oil consumption, and timing chain wear—even though they used different engines.
His first truck, a 2013 F-150 with a 3.5L EcoBoost V6, developed a cold-start rattle that grew worse over time. The second, a 2020 model with a 5.0L Coyote V8, burned oil so quickly the engine risked starvation. Both required repeated repairs.
Identical failures in different engines
The 3.5L EcoBoost’s problems come from variable camshaft timing phasers, which wear out early. When oil pressure drops—often after hot shutdowns—the phaser’s rotor slams against its housing, causing the startup rattle. Ford released technical service bulletins to fix the issue, but the solution didn’t always last.
The 5.0L Coyote V8 has a different flaw: plasma-transferred wire arc cylinder liners. During heavy deceleration, oil gets pulled past the piston rings and into the intake manifold, leading to excessive consumption. A lawsuit against Ford claims 2018–2021 models with this engine burn oil at dangerous rates.

Pasko’s situation isn’t unique. Extreme climates like Chicago’s freezing winters and high-altitude towing in Colorado speed up oil breakdown. Thin synthetic oil struggles to reach the engine’s top end during cold starts, starving the phasers of lubrication. This causes permanent damage over time.
Choosing simpler engineering
After repeated frustration, Pasko replaced his F-150s with a 2026 Ram Rebel featuring a 5.7L HEMI V8 and ZF 8-speed automatic. The Ram’s pushrod overhead-valve design removes the dual-cam phaser system that caused problems in his Fords. Its naturally aspirated V8 also avoids the turbocharged EcoBoost’s lag and heat-related stress.
Pasko shared his decision on the Ram Rebel Owners Facebook page, calling the switch the best choice after years of frustration. His experience aligns with a growing preference for proven, low-stress engines that handle real-world conditions.
The 2026 Ram Rebel’s 5.7L HEMI may not match the F-150’s fuel economy or towing capacity on paper, but for owners like Pasko, dependability outweighs numbers. After two unreliable trucks, he chose an engine that won’t leave him stranded.
