Bought an '03 Taco 4x4 double cab from a good friend. He was the original owner. 88K miles, babied since new. Complete service records and all. I was cruising down the road when I heard a chatter the. Lost all oil pressure. Shut it down and in dis belief saw a huge hole in the block and Oil everywhere. Has anyone ever had this happen with such low mileage????

Yea I'm super bummed. The truck was really babied. Garaged its whole life. Now I'm looking for a JDM import motor with around 50K miles. It's cheaper than getting a remanned long block or a short block for that matter and most of them come with all the accessories and manifolds attached.

Rods just don`t fail like this .
fess up and tell what really happened.
I have heard of things like this happening just from the change in driving style.
In almost any engine
from being driven in the normal type of driving .
To some one with the right foot always on the floor.
just how many rpm where you pulling when this let go??
What else broke when the engine locked up??

Why does the intake need to be swapped? All in all the long block should be the exact same as mine correct?

I've personally heard of one or two other low mileage (>90k) that have thrown rods. It's kind of a fluke, but does happen. A friend of mine had one with 60k he just did a short block on 6 months ago. Same situation. Always dealer serviced, babied, yata yata yata. Guy said he left a stop light, hit second gear, and bang, rod off #2 said bye-bye to the crank by making its own side exit through the block. Nothing else was amiss internally. Just one rod missing. Scan tool showed in the freeze frame data that it popped at about 3000 rpm, with mid throttle, so it supported the guy sayin he wasn't bangin on it. Every engine design is gonna have a few bad apples. They're all gonna have a few that seem to fail for no reason at all. A lot of times, it could just be a machining defect from the factory, or a weak spot in the casting.
Edit-any pictures of the failure?

Someone over revved it or ran it in the rpms alot. These motors never do this unless someone runs em in the red.
May have been him, may have been you. 3.4's are not a motor to hammer on all the time.

When was the oil last checked? Changed?
Unless it was somewhat brutally overrevved, it probably is due to oil starvation.
A quick teardown would be revealing, before you take the engine off for scrap.
You'll likely see a damaged bearing on the thrown rod.
If not, it was probably over stressed at some point in the past - either over revved or perhaps lightly hydrolocked. Damage to a rod can sometimes very slowly propagate toward failure.
If the bearing is scored and damaged, it was likely oil starvation. Either the oil was low, or the oil pump was not putting out enough oil, or the flow to that rod bearing was blocked somehow.
