Frequently asked questions
Which Dacia Logan / Sandero engine is the most reliable?
1.6 16V (K4M) — Reliable verdict. The 16-valve K4M — more refined and more reliable than the 8v, and the better petrol choice; the LPG-converted ones are common and hold up well past 200,000 km. 'Reliable' is fair, but it has the family signature: the dephaser (variable-valve-timing) pulley rattles on cold start as it wears, a distinctive top-of-engine noise. Keep the timing belt kit on schedule (the idler/tensioner pulley, not just the belt, is the failure point that bends valves) and replace coil packs as they go, and it's a genuinely dependable, cheap-to-run engine.
