REBUILDING A CHEAP BMW M5 COMPETITION | PT 3

The video documents a highly hands-on rebuild of a BMW M5 Competition, focusing on the arduous process of pulling the engine, repairing damaged components, and reinstalling everything with a focus on structural integrity and reliability. The creator revisits the project after an earlier strut tower replacement, highlighting the substantial damage found and the decision to tackle the engine work without specialist equipment. A central challenge is repairing the inlet manifolds and associated water pump and thermostat housing, all of which were damaged or broken in the crash, making it clear that simply dropping the engine back in would lead to future failures. The narration emphasizes meticulous attention to detail as parts are swapped, including a brand new BMW water pump, a fresh inlet manifold, and a corrected belt routing, with explicit discussion of the costs involved and the difficulty of sourcing OEM components. The episode also expands into suspension upgrades with KW adjustable springs to maintain ride height control and adaptive damping, a crucial step for a car that previously suffered from structural and mechanical compromises. The plan extends to exhaust and emissions considerations with upgraded down pipes from Evolv and an attempted OPF delete, followed by tuning input from Malib Performance, illustrating how aftermarket improvements can alter breathing and performance. The final act centers on reinstalling the engine and subframe, reattaching electrical harnesses, fuel lines, and the steering rack, while confronting a stubborn brake bleeding challenge that threatens to block the ability to move the car under its own power. The video closes with a tense but optimistic test start, the car roaring to life and the crew weighing the next steps, including completing the remaining repairs and confirming the car can be driven outside for test runs. The creator also interleaves light-hearted moments, like snack breaks and banter with his dad, underscoring the personal and collaborative nature of long-form car builds and emphasizing perseverance amid setbacks. Viewers are treated to a transparent chronicling of the costs so far, including specific line-item pricing for the intake manifold and water pump, and a candid discussion of ongoing uncertainties about the final look and performance after upgrades. The episode ends on a cliffhanger note about whether the car will reliably move under its own power, inviting viewers to stay tuned for the next installment and the continuing evolution of the project.
