3.0 Di ZD30 engine: faults and reliability

• 3.0 Di 158 hp (ZD30DDTi, Patrol GR, 2000-2004)

  2000–2004 · 158 hp · ZD30DDTi

  With caution

  Patrols from the early years are worth buying if there is proof that they received the oil correction and were well maintained: Nissan revised the oil capacity in 2000 and burnt pistons are documented, although Auto Express (2005) rated the diesels as very reliable.^[1][2][4]

• 3.0 Di 160 hp (ZD30DDTi, Patrol GR, 2004-2010)

  2004–2010 · 160 hp · ZD30DDTi

  With caution

  The sources consider the turbo problems fixed by the redesign, but CarsGuide (2009) could not confirm that later Patrols were free of burnt pistons; it is worth verifying the maintenance.^[8][9]

• 3.0 Di 154 hp (ZD30DDTi, Terrano II, 2002-2006)

  2002–2006 · 154 hp · ZD30DDTi

  With caution

  We have not found sources on faults specific to the 3.0 Di in the Terrano II. RAC says the Terrano II has a reputation for not breaking down, and AUTO BILD (2002) reports that expensive engine failures are almost absent, but that survey covers the 2.4 and 2.7, not the 3.0.^[10][11]

• 3.0 dCi 136-156 hp (ZD3, Renault Master II, from 2003)

  since 2003 · 136–156 hp · ZD3

  With caution

  It is a derivative of the ZD30 and we have not found sources on its reliability; it is worth checking the maintenance history and not extrapolating the Patrol's faults without confirmation.^[12][13]

Buy: No known serious faults, or they have already been corrected, in this version. With caution: Worth buying if something specific is verified: history, a replaced part or a completed campaign. Avoid: High risk of a serious fault that is hard to check for or prevent.

1. 1Critical severityFrequency: CommonCylinder head and blockBurnt or perforated pistons from insufficient lubricationIn the 3.0 Di of the Patrol, mainly in the first units from 2000, the pistons (almost always number 3 or 4) can burn or perforate and force an engine rebuild. Nissan increased the oil capacity; the Australian press still reports cases on later cars.
2. 2High severityFrequency: OccasionalTurboVariable-geometry turbo stuck and overpressure spikesThe ZD30's variable-geometry turbo is a documented weak point: Wikipedia says the problems with that geometry were resolved with the 2005 Patrol redesign, and a turbo manufacturer describes vanes stuck by soot and pressure spikes. These spikes are also cited as a possible cause of melted pistons.

Technical data^[5][6][7]

1. 2000–2004

   3.0 Di 158 hp (ZD30DDTi, Patrol GR, 2000-2004)

   The 3.0 Di replaced the 2.8 TD in the Patrol GR in May 2000, with 158 hp (116 kW) and 354 Nm. The British press in 2005 recommended Patrols built after the December 2002 redesign.^[4][6][7]

2. 2002–2006

   3.0 Di 154 hp (ZD30DDTi, Terrano II, 2002-2006)

   In spring 2002 the Terrano II received the 154 hp 3.0 Di taken from the Patrol, alongside the 2.7 TDi; the 2.4-litre petrol was withdrawn that year.^[10][11][14]

3. since 2003

   3.0 dCi 136-156 hp (ZD3, Renault Master II, from 2003)

   In the autumn 2003 redesign the Master II received a 3.0 dCi of Nissan origin, derived from the ZD30 (code ZD3), with 136 hp (100 kW) according to German Wikipedia and 136 or 156 hp according to French Wikipedia.^[12][13][16]

4. 2004–2010

   3.0 Di 160 hp (ZD30DDTi, Patrol GR, 2004-2010)

   From October 2004 the 3.0 Di rises to 160 hp and 380 Nm; German Wikipedia attributes this update to common rail injection. English Wikipedia says the variable-geometry turbo problems were resolved with the 2005 Patrol redesign.^[6][7][8]
