Have just took my turbo out of the car to clean the vnt. Couple of days ago, after some reving, police siren sound occured, well this is what caused it :(...

I was hopping the siren sound was just split in the pipes but now it looks like it will be more expensive just new pipe....aaaagghhhh.

At least I can justify the hybrid so xman will be busy sourcing parts.

Ouch, what would cause the impeller to break like that?

Good question. My girlfriend uses the car mostly for her 5 miles commuting to work through city centre traffic so every time I am behind the will I try burn the **** out by using all rev range. This time though, after holding the rev counter around 4k rpm, the turbo started making police-siren-like sound around 1500+rpm. When I removed the turbo, I realised it wasn't split in pipe as I was hoping.

The car was pretty much standard when I bought it and the turbo is still the original one so is 7 years old and ran for 130k miles.

The lose piece most likely ended up in cat, can it cause any trouble if left there or do I have to take the cat out and try clean it somehow?

So new turbo arrived (thank xman) and will be installed today. We managed to broke one of the bolts connecting pipe to egr cooler so will be blocking off the egr at the same time. Question is do I have to change the oil if the car have been serviced 5 weeks ago? Or do I run the car for few days and then change the oil? Or will it be ok just to leave current oil in? Just a reminder the turbo didn't die due to bearing failure and old oil from the last service didn't have any visible foreign particles in it.

Current oil should be fine if you've been careful with open ended feed pipe, oil filter will catch anything untoward.

Just a thought, my old pug had an inline filter on the turbo oil feed, hard to spot and easy to lose as it fitted into end of pipe.

Ensure you have one if it's meant to have one, mine was metal gauze so easily washed in petrol and reused.

Thanks for the reply.

Well I took the oil feed out just to make sure it's not clogged inside. Sprayed carb cleaner into it until only clear cleaner poured from the other end and then blasted all out with compressor. The same for the return pipe. Haven't got any inline filter in it...or at least haven't seen any. I think no need for new oil, don around 500 miles on the current one.
