M35 - Dying Turbo?

[PetroDola]

Getting some lifter sounds now the exhaust has been done which i suspect is the turbo dying .. sounds like compressor wheel scrape as when i rev high the scrape continues after the rev has dropped for a good 5 seconds after the engine has backed off.

Although theres another issue. I believe the radiator guys when blowing out the oil cooler topped up the tranny with dextron III but that wouldnt account for the continued scrape spining sound in park.

It does however over rev alot in 4th and 5th when on boost around 100. but a gearbox fluid flush and change on monday with proper matic-s fluid should hopefully correct that.

Any ideas?

Heres a video of the sound!

definately compressor wheel scrapage?

:S

I cant really hear it mate.

If you are driving it down to Sydney, Craig (Jetwreck) is willing to have a listen for you... Perhaps you can swap turbos when he's not looking.

good news mate.. looks to be a lifter noise right adjacent to the turbo...all good for now, turbo seemed fine, have also found a vacuum leak on the injector side. got noisy injectors also heh.

5 DegreesCentigrade temps on country roads certainly show you why you need a proper intercooler, response was insane.

also worked out why my stag winds off the clock way past 180 and was wondering why everyone elses stops at 171/172. .. its almost 14kms out the speedo!... couldnt believe it when the gps corrected me and the road side speed tests that corelated what the gps said.

no wonder people had been sitting on my arse the past 2 weeks!

I have to sit on 111 to do 100 by the gps.

Glad its not the turbo but ours is buckets and shim, shouldn't be making noise... Perhaps it's an exhaust port leak?

Better get it checked, did you get it from a dealer?

[PetroDola]

exhaust port leak kinda matches the sound .. ill need to get it checked out.

It was bought privately from someone who bought from an importer in melb last november.

doubt that warranty would carry over to my ownership but not sure. i guess i should check it out.
