Thumbs down OIL in engine bay......looks like its from turbo

can anybody shed some light on this isssue i have got.
was hammering my car home yesterday and noticed white smoke coming from bonet

thought there was l leak, but the car seams to have oil on the top of the bonet and the right strut.
well basically there is a lot of oil in that part of the engine bay.
looking around i noticed that no hose were loose and that the turbo oil feed hoses are all tight and not leaking.

now i did notice that the vacum hose from the turbo compressor side has come loose, could this be where the oil is coming from being blown out as the hose broke of near the end.

but it does not make sense that the there is so much oil coming from there.


anybody know anything about this
the car was fine driving here was hitting 20.5PSi boost.

thanks

if that hose came off your compressor nipple, your wastegate wasn't regulating boost and you were overboosting enough to roast your turbo's oil seals. Check the turbo for damage. Also, check your CV boots and power steering lines just in case. My money is on a blown turbo.

thanks for the reply man, wasnt overboosting as was keeping an eye on boost gauge
and i have a knock link on car so there was no knocking and boost was pegged at 20psi
and this is a Deadbolt 20G.

Luckily for you, a stocker TD04 with low miles can be had for under $150. But it's no 20g. Will Deadbolt hook you up with a rebuild? Isn't that part of their deal?

well took the car for a drive and it doesnt smoke now
the problem when it starts it smokes a bit, but will take it back to the tuner and see from there.
we will do compression test etc and see what the deal is

Do you have smoke comming out your exhaust? If no, then i doubt it's a blown seal, i would guess that you have a leak under the hood somewhere.

Could be blown oil return line. The line is pretty hard to see with the turbo installed.

Check out this thread I started when I discovered such a problem in my car.

Nope not leaking from the exhaust return.

fixed the vacuum hose on compressor housing going to the boost solenoid and it seems better, no more oil in engine bay.
can i blow the turbo seal on turbo if the vacuum came off while driving?

I will take it for a ride tom and see from there, could It be that there is still a bunch of oil in intercooler and inlet pipes?

lke i said i was monitoring the boost and it did not seem to overboost at all, pegged at about 20psi.

pity the car was oing so damn well

ok cleaned the engine ba etc and there are no leaks since i fixed the comp vacuum hose.
But started the car this morning and a whole bunch of white smoke .....
smelt like oil and checked the oil level and it is down.
No leaks under car either so i reckon 2 things have happened .

1: turbo seal blown
2: i have dmaged the oil rings on one of the cylinders.

umm cant think of anything else, unless what supermarkus said was true that due to overboost i have damaged the seals :-(

Luckilly stock turbos can be had on the cheap. real cheap. ~$100 or so for one with relatively low miles.

Just some feedback for you guys if anybody interested

took the car to the tuner and we ran a compression test on car

Cylinders 1,2 and 4 have 800kpa and Cylinder 3 600kpa.

so it seems that when the pipe came off the compressor housing it must have overboosted and damaged one of the cylinders which would be cylinder 3 as it is the cylinder with the lowest compression.

Sad indeed, like i said....... the car was going great.

Oh well time to save for a 2.5L Axis block.
**** man just blew up at the wrong time
