Restoring Power and Reliability to the Magma 12 Valve Engine
In today’s technical vlog, we’re diving deep into the engine bay to address a common but messy issue: a major oil leak coming from inside the distributor. After 15 years of faithful service since 2007, the original Mitsubishi unit in my car is finally heading into “retirement” as a backup spare.
What we cover in this video:
- The Diagnosis: Why a broken internal O-ring was causing a “bad leak” and affecting engine performance.
- The Upgrade: Installing a brand-new APM Distributor (RM400) and comparing it against cheaper RM150 alternatives.
- Side Repairs: Fixing a broken water temperature sensor wire and a quick temporary fix for a faulty inner door handle.
- The Results: Does a new distributor actually make the car feel like new? (Spoiler: The “taktaktak” noise is gone and the throttle response is back!)
Whether you’re looking to restore your engine’s lost power or you’re curious about the build quality of APM vs. Original Mitsubishi parts, this step-by-step walkthrough has you covered.
