Car mechanical issues: engine replaced, now turbo has gone

I weighed up buying a new vehicle instead of replacing the engine, but that would have made it worthless when trying to get rid of it. The car itself was worth significantly more (to us) by having an (lower km) engine replacement.

Regardless, with a new (second-hand) engine with a warranty, fitted properly with testing, and a full service, you'd expect a few more than 500m-1000m from it all.

Ok, this puts a different spin on things.
So what has actually happened is a belt tensioner/ idler bearing (roller bearing) has seized & it has thrown the cambelt off. This is completely external to the oiling system & wont cause contaminated oil & the engine ceases to run at the exact moment of failure, so essentially it didn't "grind to a halt" this kind of throws up more questions than answers.

Id say he's not entered in the competition, unlike you & I.

Yep, I would be asking a whole lot more questions, and asking to see evidence of lunched engine. Thats if it has not been given a new cambelt and tensioner and sold to someone else as a reco'ed motor.

if you post up or pm the rego I can tell you if its an interference motor & wether it did in fact bend its valves etc.

So unless its a 2.5 DOHC then it didn't bend the valves.

Imagine if a Holden 6 smashed it valves every time the fibre gear broke.

Do you have an oil cooler on the car? If the old engine ate itself they can be a great place for debris to get caught up.

Yeah, sounds more like a timing belt component or water pump failure, if they suspect something else it's not worth going any further, just put in another engine. My daughter's '89 Omega had an oil pump pulley failure last year, but she's smart enough to see the oil light didn't go out and heard the noise, so a cheap fix. They have no real idea of the condition of the replacement engine, just she's a good runner mate...and they usually are. We are having probelms with diesel Kia Sorento's at the moment - injector seals leak, allowing carbon into the engine, this blocks the oil pickup and the first thing to go is the turbo. I've done a couple, and replaced injector seals on 3 others (that's all we have in the area) as preventive maintenance. No damage to the rest of the engine.

So something as simple as the oil pickup, the oil light will still go out, but the turbo will be starved.
