Thread: some EGR thing

its actually the EGR heat exchange that cracks.
Its not so common on a 2.4 but very common on the later 2.2

now the turbo has died, going well

don't buy one in a green box. they are common to a dozen cars and can be bought for 1k cheaper

do yourself a favour and get a gasket and stud kit also. Soak the bolts in a mix of 50/50 ATF/acetone or a like penetrant overnight.

If you are on a budget, the chinese knock offs do the job. i ran one for 18 months but went back to genuine garrett. you can have my chinese knock off for free. nothing wrong with it. the reason i pulled it off was the brand of silicone hose i was using would not clamp on the high pressure outlet and kept backing off under full noise. i pulled my 2.4 engine for an LS and have no use for the engine and all the spares i'll collected over the years. I'm selling the engine so won't pull the garrett from it. noting you are in Canberra, I can take it to Goulburn if you wanted to collect this weekend. I'm down that way to do some work. If not this weekend, i live in Stanwell Park NSW and can collect at your leisure. Or politely say No thanks.

no thanks i have gone the expensive route and am paying to have it done
i think i need to start a mechanic apprenticeship

i am appealing to the great store of knowledge out there

the mechanic couldnt find the cause of failure in the turbo
the oil was flowing from the pump so that was not the supposed cause
no damage from sucking something in
its thought the cat was a little obstructed (it was slightly down on power) which meant the turbo overheated

i am wondering if anyone has experience with a failed turbo (overheated and the shaft broke) that wasnt from lack of oil
i am feeling more than a little annoyed that i had the top of my engine rebuilt and then the turbo just happened to fail

failing turbos are very common on the Defender TDCi 2.2, poor build quality, the bearings collapse often jamming the spool against the housing shearing the centre shaft.
I have had them fail as in the customer drove it here but if felt under powered the centre shaft of the spool had sheared in half. Others turn up on a tilt tray where the housing has cracked open like an egg.

New gen or garret ones are of the same poor quality. Many a year ago both Ford (u.s) and Caterpillar i believe took legal action against them due to the high percentage of failure rates, garret went into receivership and was no doubt bought by a money management company, so build quality is likely to not be high on the agender. (i am paraphrasing)

I rebuild them (for my own use on customers defenders) using cores manufactured in the U.K from turbo rebuild Turbo Rebuild Ltd and i ceramic coat both snails, i also ceramic coat the exhaust manifold. I also put on a free flowing first exhaust section which is also ceramic coated which i believe reduces the heat soak into the turbo and engine.

and yes the intercooler is a good catch all between the turbo and engine, but it may also need replacing due to damage with the turbo hoses. Both items are a common failure anyway

Is the turbo actuating arm moving OK or is it stuck? Sometimes, all you need to spray some lubricant onto the pivot points. You can add this to your maintenance schedule to ensure it doesn't get stuck.

DazzaTD5's answer and findings are concerning but they do make sense considering.

shaft snapped and made a nice rattlley sound. i think Dazza has it. i just didnt want to feel like i was being taken for a ride
