Had the pleasure of diagnosing a misfire on a Toyota Hilux. Bombproof so I hear everyone say. Orignally blamed as a injector problem....erm nope, maybe initially...but not now.

Kudos awarded to anyone who can spot whats wrong in attached picture (yes the rear piston is wet, but thats not the main problem). Clue; crank is set with no.1 at TDC

Wow that some hole lol

Det or ring land or piston failure ?

Bent rod on no 4 cylinder, it dosent look like its hit the top of the bore / stroke yet, whereas it looks like no1 is, also possible dead little end / gudgeon pin too.

Mmm, is this a common issue or a one off? The wife drives a double cab 3.0 invincible. What year is this one?

My daily is a 2001 hilux 2.4 and its clicked over to 155k, I find as with all cars etc look after it and it will run forever, treat it like a mule and the above will happen.

We've had a 09 plate and now a brand new one in work, constantly breaking but it just gets abused 24 hrs a day 365 days a year.

We have a winner; Piston no4 is about 4mm below the deck whereas no1 is pretty much level, they both should be at the same height. Piston looks on at the top, no dents or holes.

Guessing its been hydrolocked at some point.

Owch.

(ps 3.0 D-4D. 2007 IIRC )

Hydrolocked ??

It what happens when liquid enters the cylinder whilst the engines running, liquid isnt as compressable as air so it tends to bend rods. Most common occurence is driving through deep puddles and the water enters the engine through the airbox and ends up in the cylinders.

Ah, that may been what happened to mates 306 when he unwisely decided he could get through that puddle lol

but that isnt a reliability issue, thats a "i can take my hilux through a river issue"

i agree its hardly just broken.
any engine sucking in water will hydrolock and die.

Actually it isa reliability issue...as it appears to have hydrolocked with fuel....(hence wet piston). I don't think it was driven through a river of diesel!

Inlet is bone dry...teh air filter box is the size of a Henry vacuum cleaner

vindaloo

Injectors been out at all?

Probably.

Injector/seating issues are pretty common on these.
