: If blue smoke persists constantly while driving, the oil control rings on the pistons are either worn out or seized with carbon buildup.
Every 5,000 to 7,500 kilometers (or every 6 months).
Rotate the crankshaft clockwise two full turns to distribute tension evenly. Re-verify that all TDC marks still align perfectly. Torque the tensioner bolt to specification. Step 4: Reassembly A common issue with high-mileage 5A-FE engines is
