View Full Version : Car mechanical issues: engine replaced, now turbo has gone

My wife's car broke down two weeks ago, the bearings seized and caused the cambelt to disintegrate - destroying the engine.

Half a week later a new (second hand) engine arrived at the mechanics, and they had it in the car in one day, with "thorough testing", then spent the next giving it a full service at our request.

Car was fixed. Yay, but expensive.

After having driven the car for less than 1Km from picking it up from the mechanics, home one day, and then to the supermarket the next, it broke down.

1Km. Less than 1Km to be precise, and all at speeds under 50Km/h. She's gentle on the acceleration as well.

Now it is back at the mechanics and they are telling her that it is the (original) turbo that has packed up, the same turbo that they removed, and then put back on the new engine, possibly damaging the new engine by releasing metal particles into it.

My question is, who is responsible for any further costs? Us because it is the original turbo that has caused the additional damage? Or the mechanics who have removed, and then reconnected the part (possibly not properly) before it failed?

Thoughts from mechanical experts, law experts, and general KB keyboard warriors welcome.

You would have a very good claim to be made under the CGA.

All work should be carried out with Due care and attention - since the car broke down less than 1 Km after being fixed, your argument would be that clearly the repairs weren't carried out with due care.

Was the turbo inspected before being replaced? it would seem that a worn out turbo that was due to fail should have been identified. Also, did the replacement engine come with a turbo attached? Presumably they ordered one without a turbo as it would be cheaper, there may be a claim here that they were cutting corners instead of ordering the correct replacement (may be harder to make that argument)

Depends what you instructed them or agreed for them to do, and what is detailed on the receipt for the work.

What was the cause of the bearing failure, and which bearings?.

presumably big end. Presumably oil starved/ pump failure.

Presumably turbo should have been checked. 'letting metal into the engine' sounds like a fuckup. A 'full day service' presumably includes 'checking that it wont fuck out 1km later'

presumably a turbo engine dropped in, unless they swapped the manifold and plumbing off the original, which should have been thoroughly checked either way.


I'd say it's their cost.

Turbos frequently shit themselves & I have never seen a case where it wrecks the engine.
I have a diesel BMW X3 here at the moment that has shat the turbo big time, apart from draining & flushing the intercooler of oil & the same with the entire exhaust system (the longest & messiest part of the job) experience has taught me to look no further for damage to the engine. To give it a new air filter and an oil & filter change or complete service is about as far as I will need to go.
To be fair the garage involved will be pretty crushed at the current outcome & probably used your old turbo in an effort to save you some money, as im sure if turbos were free they would have had no hesitation in chucking it a new one, which was fairly noble of them.
Weather or not you had put them under any pressure to keep the price down I don't know, but bear that in mind when dealing with them.
A good bastard would charge you for a turbo & fit it labour free as a gesture of goodwill, weather they do that or not remains to be seen. But suffice to say, the cost of the turbo is yours, not theirs.
I have no idea what the legal angle is, a my sense of what is right & what is wrong kicks in long before anyone would ever need to get lawyered up.

There are several things that fit "the turbo has failed'

Oil starvation. Seals leak. Bearings fucked. Housing cracked. Mounting surface warped. Wheel flies apart.

If a turbo fails on the exhaust side often little to no engine damage occurs. If the failure occurs on the inlet side trouble ensue.
The turbo is lubricated from the common oil source.
If an engine has seized the oil supply and feed lines are contaminated.
Sounds to me that they haven't been suspicious enough in ensuring the repair is complete.
If a turbo was 10 min away from terminal failure due to normal wear and tear then this would have been apparent. The failure is as a result of something not right rather than a case of 'bad luck'

Absolutely. The turbo failure is related to the original problem & not just an amazing coincidence. Don't be buying that story.

Thanks for the advice/ideas guys.

I've spent a little time today doing some research, even contacted an authorised Subaru dealer/repairer who said that it's not necessary to replace the turbo when swapping the engine, and it's actually quite expensive as you can quite easily check to see if there is anything wrong with it that requires replacement once it's been taken off of the old engine.

You'd certainly notice if the turbo wasn't operating properly from a visual inspection once off the engine, and should be able to tell if it was less than 1Km from complete failure.

I don't have much info as my wife has had to deal with all of this herself and she was concerned by what they were saying to her. I've gone and seen the mechanic in person as I'm within walking distance, and I've come away feeling a little suspicious of the words/tone the business owner is using as well.

They don't know what is wrong yet, but they've already taken a defensive position - before being asked a single question.

I'm just gathering info, and sorting out a next step if one needs to be taken.

What caused the bearings to seize? can really only be oil pump failure ( rare) or lack of oil ( not so rare)

I don't know anything about the initial problem as I wasn't there, don't drive the car, and it was towed directly to mechanic's yard.

My wife was told: "Cambelt disintegrated due to seized bearings, which ruined engine". I'll have to track down the paperwork when I get the chance, it's probably still in the car...

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.

Not in a Subaru. I'm picking it is a Legacy? Very easy to blow a big end on them, most the time it is because muppets put boost taps on em and up the boost, but even in an unmolested example it can happen.

I would say you have a very good case against them if it has damaged the replacement engine. Either way I would hit them up for a replacement turbo, shouldn't cost em too much to source.

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.

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.

Motu
19th August 2015, 18:20
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.

Dunedin City Ford rebuilt my V8 years ago and it lasted 500km.
Cam moved and pushed the cam chain against the cam cover putting ally through the rebuilt engine.

Took them to small claims and it turned out the work was done by their first year apprentice at full hourly rates.
They blamed the second failure on a worn oil pump and got away with it.

I remember when I took it there asking why there rate was higher than other shops.
"We are Ford and we know them inside out" was the answer I got.

The low boost symptom sounds very much like a loose hose-clamp on a pipe, bleeding air. (been there)
Your turbo would have to not spin to get no pressure. Is it seized?
You would need to personally see the turbo and handle it to find out. (I think this is most important)
Knackered, smoky turbos still produce boost (been there too) and yours was not smoking, from what I read.

Well according to the person who took the turbo off, and put it on the new engine, they inspected it and it was fine.

Now they want another $1000 to put another turbo on, but they'll fix the replacement engine for free.

I can understand the garage's reluctance to put time into replacing a cam belt and assorted attaching parts, only to find there is further engine damage and then have the ensuing argument with the customer over who pays the bill so far.

If the turbo was checked by a competent mechanic before fitting it seems unlikely that it suddenly reached end of life after another 1km of use, more likely there was some crap in the oil system when assembled which blocked the oil feed to the turbo, which without oil would probably last about that long before it shit itself.

Seems to me in this case it's on the garage for either poor workmanship installing the parts, or installing parts they shouldn't have if they were that close to failure. I'd certainly be arguing the point.

Im a sparky and understand what your saying but if you quote a top end engine rebuild (20 years ago) at $2.5k and 500km later the new cam you installed eats the cam cover putting ally through the engine you should at least have a look at the car which Dunedin City Ford refused to do.

It is absolutely part of the game.
If you're a big enough man to open a shop & take people's money for putting their cars right, you also have to be a big enough man to own it when you get it wrong.
Your primary objective is to fix only what is wrong (if it's only a cambelt, fit a cambelt, not a whole engine) & minimise the chance of a repeat failure, & if you fuck it up, say sorry, give them a loan car & sort it out at no further inconvenience, financial or otherwise.

Look I know zero about subarus other than I had a daughter buy a 2.0 twin turbo that sucked money and turbos faster than it could drink gas. However a colleague of mine has an ancient RS turbo wagon he bought NZ new waaaay back. We are talking one of those square edged things. Its been as solid as a brick and he seldom maintains it. ie he drives it until a cambelt pops and then fixes it and forgets about it until it pops again. Never any damage to the engine... He reckons it can limp home on 2 as it has 2 belts (I think hes full of it)

This sounds expensive...

Interference motor means the valves can tangle with the piston when a cambelt breaks Drew. Not all motors are interference. Indeed a heck of a lot of belt driven cam engines are not.
The Tensioners that seize generally are not on the cams

I disagree. I had the cam seize on my 2.5 diesel, stripped the cam belt but motor was far from fucked. Different cam and caps and a new belt and it is still going hard.:2thumbsup

Its not "one size fits all".

In fact their are a few knowitallwithouknowingthefacts comments in this thread.

Indeed....

non interference engine has enough clearance between top of piston at tdc and fully opened valve not to do damage....

interference engines dont have enough clearance....

belts wear out after x amount of kilometers,
tensioners seize or shear of after a while..
the bearing fails...
balancing shafts ad to the list of things that can cause failures.
Old and dirty oil doesn't help.
bent valves not to costly...
getting holes in pistons bit more of a headache....

change oil and filters regularly,
do timing belts, tensioners and waterpump at recommended intervals....

Twin cam engines can still bend valves even if they do not interfere with the piston if the cams get way out of sequence.

Valve to valve contact.

Fuck off cunt. I know the difference between an interference motor and non.

But who the fuck would pay for the number of hours required to fully investigate if the cam was the only issue?

No damage to the bearing surfaces in the head? Lucky.

How about you look what you wrote and what was quoted and what the OP said.
Then seeing as its Friday go down the local fish shop get a fish and beat yourself about the head with it.

What Drew is saying is possibly an oil starved cam seized in the head which damaged belt/tensioner setup. Either way no one has the full story and its all guestulation.

Yeah maybe, but look at the post Drew actually quoted.

Yeah I still donīt see it - Frosty couldnīt see how a broken cam belt on a non-interference engine could write the engine off - Drew gave a possible scenario.

No where near enough use of the word Cunt though.

Minimal, but not "none" I will admit. But the fucker still runs, and has done for a couple of years.:msn-wink:

Nice. You'd prolly not do the same for a paying customer though I'd expect. It's a gamble those of us who do our own spannering are willing to risk I reckon.

But you are right, unless they were as rough as me and were willing to gamble. :niceone:

Haha, that escalated quickly. I think a few assumptions have been made, and most of them were unfortunately incorrect.

As per my last post, a positive outcome has been reached, allowing the mechanic to save face, and the car should be ready by Tuesday.

Sorry dude I deal with this shit day in day out. Have a look at a pic of the cambelt set up in one of those.
It is NOT a Subaru recommended practice to automatically replace the idler bearing. BUT lazy mechanics leave out the part that Subaru DO say needs doing which is to check the idler for any indication of rumbling/wear. If it spins smoothly then it can be reused. If not then must be replaced.
Failure to carry out this step THIS causes cambelt teeth to strip.

So its well worth finding out if the idler is seized because often that is the full extent of the damage. -and well worth spending the $75 and 15 minutes extra labour it takes to put the belt on and see whats happening. You will know really fast when you hand crank the engine if it is or isn't seized.
Then if it is I would swap the new belt to a replacement engine before it goes in the car. AND I'd be checking the idler bearing.

To be clear. Im not saying this is whats happened in this case. But I sure as eggs wouldn't bypass checking it before launching in and fitting a new engine.

UP;s to Frosty, Kylie and Millars cars Henderson. I purchased a Toyota Rav of them in December 2013 and just sold it last month. Apart from basic maintanence that ALL vehicles need, after sale, it worked out that the car had cost me .62 cents per day to own. Cheaper than Chips. Thanks team.

That's great news.

Like one of the other fullas has said, could you please post the details of the outcome.

Thanks :niceone:
