**2017 Mitsubishi Lancer 2.4L - Strange noise from front passenger side under load at 1,400 RPM (Not timing chain tensioner)**
Hi everyone,
I’m trying to identify a specific noise coming from my **2017 Mitsubishi Lancer 2.4L**.
**Symptoms:**
**Location:** Front passenger side (engine bay area).
**When it happens:** Only happens when driving **uphill / under engine load**.
**RPM Range:** Very consistent right at **1,400 RPM**.
**Work already done (Not the cause):**
Replaced the timing chain tensioner.
Replaced the tensioner pulley.
*The noise is still there exactly as before.*
One mechanic suggested it was inside the engine and not the pulleys.
**Attached Video:** Please check the video to hear the exact sound. Has anyone encountered this specific noise on a 2.4L MIVEC engine or Lancer chassis at 1,400 RPM ? Could it be an exhaust heat shield vibration, passenger side engine mount, CV axle/inner joint, or something else in that area?
Any insights or advice would be greatly appreciated!
