Blown Turbo?

[CeJay]

Hi all, well late last night coming home, accelerated up to 5000 rpm or so, and heard a high pitched ping, backed off the car and let it coast, oil pressure was normal everything else seemed ok, tried to see if it would boost, and everytime it was just about to come onto boost could hear a metallic type grinding noise, and car would not boost. Was only about a 1km or two to home , so drove it like a granny and parked it.

Did notice last night though that the car was dripping oil around below the turbo, put an oil pan under it and checked it this morning, theres probably about 5 to 10mls of oil there.

Had a bit of a search here, I'm assuming a have a blown turbo perhaps? Will try and have a go at pulling off the intake to look at the turbo wheel, for any obvious other probs. Just wondering what else it might be? Best to trailer it to a shop if I'm not doing it myself? Best not to start the car?

Have not started to car since last night.

bottom half of the turbo also appears to be covered in oil. Havent checked the turbine wheel yet.

Okay have some noob questions, My turbo's not boosting and leaking oil, now I don't really want to go down the replace the turbo route, if my engines f**ked. So whats the proper way to do a compression test?

Does the car idle normally? Blow smoke on idle?

My thoughts would be that the metal-like noise you heard was the ass-end of your turbo heading down the exhaust.

Car idles normally, no smoke, but I've got head noise which wasn't there before, like a light knock at the rear of the engine.

you need to pull the turbo off and see whats missing first, it will only go through the motor if its the compression side, if its the exhaust side it will be in the front dump or cat. Your noise could be coming from the cat or even the turbo rear housing and just sounds like the motor.

I wouldn't be pulling motors apart until you know for sure.
