Nissan Juke: MR16DDT Big-End Bearing Failure (Oil Dilution)

MR16DDT Big-End Bearing Failure (Oil Dilution) is a common engine fault on the Nissan Juke on the 2010–2020 cars, and we rate it critical. Putting it right costs $4,500 to $12,000 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 21 documented faults on the Nissan Juke.

What you are looking at

No photograph available

We do not hold a verified photograph of the Turbocharger yet. We would rather show none than show a picture of a different part.

What goes wrong

The 1.6-litre direct-injection turbo engine (MR16DDT) is prone to premature big-end bearing failure. Direct injection causes fuel to wash the cylinder walls during cold starts, diluting the engine oil and depriving the rod bearings of adequate lubrication. Progressive bearing wear leads to a deep knocking noise and, if unchecked, catastrophic engine seizure. Nissan issued no recall in NZ/AU; failure rates remain high on unmaintained examples with extended oil-change intervals.

What you would notice

Deep rhythmic knocking or ticking from lower engine block, most pronounced when cold
Knock worsens progressively with RPM and load
Oil appears thin or has a petrol smell at the dipstick
Increased oil consumption between service intervals
In advanced cases: low oil pressure warning light, sudden loss of power

How to check it

Where to look. Lower engine block, crankshaft big-end bearing journals

Start cold and listen for a low-frequency rhythmic knock that increases with RPM.
Check oil for metallic flecks or a silvery sheen using a white cloth on the dipstick.
Verify oil service history — intervals beyond 7,500 km significantly increase risk.
Check for any recent engine top-ups between services, which can indicate oil consumption masking dilution.

Parts involved: Turbocharger.

What it costs to put right

$4,500 to $12,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Can you show me full service history with oil-change dates and mileage — were intervals always under 7,500 km?”
“Has the engine ever been inspected for bearing noise or had any internal work done?”
“Has the car ever been low on oil between services, or has any top-up oil been added?”

Now check the Nissan Juke you are actually looking at

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today. That comes from the official records for that plate. Enter the plate for the free details, or get the full history and a market valuation from $13.49.

Where this comes from

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.

Nissan Juke buyer questions

Is mr16ddt big-end bearing failure (oil dilution) serious on a Nissan Juke?

We rate it critical and common on the Nissan Juke. The 1.6-litre direct-injection turbo engine (MR16DDT) is prone to premature big-end bearing failure. Direct injection causes fuel to wash the cylinder walls during cold starts, diluting the engine oil and depriving the rod bearings of adequate lubrication. Progressive bearing wear leads to a deep knocking noise and, if unchecked, catastrophic engine seizure. Nissan issued no recall in NZ/AU; failure rates remain high on unmaintained examples with extended oil-change intervals.

How much does it cost to fix on a Nissan Juke?

$4,500 to $12,000 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Nissan Juke years are affected?

Our research records this fault on the 2010–2020 Nissan Juke. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.

How do I check for it before I buy?

Start cold and listen for a low-frequency rhythmic knock that increases with RPM. Check oil for metallic flecks or a silvery sheen using a white cloth on the dipstick. Verify oil service history — intervals beyond 7,500 km significantly increase risk. Check for any recent engine top-ups between services, which can indicate oil consumption masking dilution.
