Death Of Turbo

[Chi100188]

Hey guys just wondering how my turbo would of died....the turbo was a 3071r new cartridge everything, i had it on the car for three months ran fine then was getting it tuned, then tuner calls me up saying he ran it on the dyno on two runs then my turbo siezed so i ripped the turbo off went back to MTQ to get it inspected they wreckon its oil starvation so i checked my oil lines it was fine no debris, then checked the oil flow so i cranked the engine a few times oil squirted out of the turbo feed line like a fair bit of oil....is there any other possibility it would of siezed the turbo? the water lines are flowing they are not blocked, MTQ kept my siezed cartridge...

Cheers

oil starvation lol standard response

[R31Nismoid]

Ask for the cartridge and bearings back.

If they have blue scoring on them, sure was lack of oil.

Just because oil comes out doesn't mean it was enough or at some other time it wasn't semi blocked etc.

[hypergear]

There are 2x 20 thou oil feeding pins inside the oil feeding port. when that gets blocked up oil can not pass through, which happened to pretty much all the XF6 turbos we are rebuilding.

Its more less of a design related issue which designers assumed all engine oil is 100% clean, How ever we do have engine filings, carbon deposits and etc that are circulating with the oil. Those oil contaminates comes to rest and collected by the turbo.

[R31Nismoid]

The XR6 turbos are failing because of the inline filter though aren't they?

Which is then starving the turbo of oil. This is only happening on a specific model too...

[hypergear]

The XR6 turbo gets contaminates filled up in both filter and the pin. I did have few later model turbos in as well, XR6 turbo repair and high flow jobs are growing substantially this year (Some are due to lack of servicing or bad oil). Also happened to few other GT turbos sent in for repair. Have a close look at the relocation pin (oil feeding pin), it acts like a collection depo for oil contaminates.

Lol, an inline filter feeding the turbo? What a stupid idea. People who drive cars like Ford XR6T, VW golf GTI and other turbo charged cars sometimes forget they are driving a turbo charged car and do not service them. I know a guy with a VW turbo who does his services every 20000km. I tell him you have a turbo there which does not like dirty oil. His response? "That just happens on shitty skylines". Lol.

People also need to remember that there are manufacturing faults. Its not quite fair if Garrett or any other manufacturer just blames the end user. Sometimes shit can go wrong because of them. I bought a GT3582R turbo off a guy. Turbo done 200km on his car(all dyno work). When I got the turbo home, rear wheel was destroyed. It was replaced under warranty but I got a refund from him anyway. They tried to blame him but he always ran a filter, his engine is still healthy etc. In the end there are manufacturing defects which could happen. Some companies need to get off their high horse and put their selves in our positions.

check the oil drain as well as the feed. it's possible the feed was fine but if the drain is blocked or not flowing enough then it won't sufficient flow.

This!

[SargeRX8]

True statement made a couple of posts above but one would immediately assume that when with the way its setup, a thin hose for feed and a relatively larger hose for return, that if any junk and desposits were going to contaminate and block the lines, the thinner line would go first. But as a general rule, it is always best to look at all your lines to ensure what is and what isn't going on.

Before you strap on another turbo you might want to consider getting an oil analysis done. It will tell you if you have excess wear and rubbish in the oil. You'll also want to drain and clean everything out and ensure all the old shit is out of the car just to be sure. Run some oil flush through it followed by some cheaper oil then put your good stuff in there after letting it drain. Its off the road so let it drain really well.

i checked the oil drain as well there is absolutely no blockages....can high exhaust gas temps on the dyno cause this failure?

[hypergear]

High exhaust tem can burn turbine wheels tips which are only 20thou thick. I've had few of those too. the bearings are cooled by oil and water so the bearing housing it self is not affected unless coolant is not present. So did you connect water to the turbo?

If oil drain is blocked or having issues drain oil, the turbo would leak oil out of both ends, how ever that doesn't stops the turbo from spinning, might seiz after a long period of time.

Sounds like a good idea to me. It will take a lot more crud to block a filter than a flow restriction orifice.

They may be right. IIRC the Golf GTI's are a low boost, low stress motor. Combine that with extended drain interval fully synthetic oil, 20,000kms shouldnt be a problem.

Hey stao yeh i did connect the water lines to it...and there was plenty of coolant coming out when i took off the turbo

The way my mate drives his car is a joke. He thrashes it beyond thrashing and I tell him why didn't you just buy a second hand one. He bought it. Brand new, and treats it like shit.
