engine blow up on 2003 nissan navara

[robbie89]

Hi im just after a bit of advice and where i could possibly get a new or reconditioned engine for my navara i was driving my pick up and a con rod has appeared on the outside of my engine so a complete right off it had only done 89000 and fully serviced, has anyone herd of this before.

any advice would be great thanks alot,

a conrod through the side sounds odd. typically they blow holes through the pistons.
i would tear it down and see what the cause was. last thing you want is to have the same failure on a new engine.

Petrol of Diesel

Big end or little end sticking out of the block? Did the crank end or piston end let go? Sounds like piston end (little end)

Sounds like pissed n broke.

Petrol or Diesel?

At a guess Id say Europe and the non CRD YD25.

Its an 03 model d22 Dave so it would either be a 3.3 v6 or 3.0 diesel

uk and NZ got 2.5 litre diesels as well. the UK ones o tend to throw rods through the side. i tend to forget we get a few UK guys on here.

have a look on Nissan-Navara.net • Portal its rather common unfortunately. check what year your ute is, nissan extended the warranty due to that problem.

Dave was on the money.Well done mate.

All good Scotty, if a ZD30 lets go its usually a piston top.

Non CRD YD25's are prone for it as the big ends bearing aren't designed for the load there taking.

exact cause hasn't been established, but the bottom end strength wise is fine. the problem is bearing related. the bearings look like oil starved. wither its poor bearings or poor installation is debatable.
i suspect nissan got caught with the change to non-lead bearings. either the factory used wrong clearances (or quality control is crap) or the oil pump doesn't flow enough for the alloy bearings.
