ABY - what blows first

[UrS4boy]

...However, from the small piece thats visible it looks like a metal gasket.

Even the "paper" head gaskets were metal at the edges and around each of the holes, including the cylinder bores so seeing metal at the edge doesn't mean that much.

The only 20vT headgasket available now is the all metal 034103383AD (3B, AAN, ABY and ADU) -

Mine was one of the last ABYs and had a 'paper' gasket...

- Turbo dead

Well Im not sure if this is cause or effect but its certainly interesting. The wheel is siezed solid in the housing, you can see the nut that held it on inbetween the blades, just out of sight is the end of the shaft wedged further down in the turbo.

My main concern is what other damage has been caused from the debris. The intercooler had a nice pool of oil in it but no other parts removed yet.

[andyg plym]

oil in the intercooler is perfectly normal

havent had an s2 yet that hasn't had oil in there

Bit of wd40 will fix that
Need to take the head of check pistons foooook

Yeah, probably put a couple of zip ties on too, just to make sure

[QuattroFever]

it's ingested it's own nuts!

What pressure did it see?

Use some endoscope and make a leakdown test. Maybe that way you don't need to remove the head....

On the other hand maybe a valve/part of it flew out of the engine and hit the turbo.

Possibly but it still got me the 8 mile journey home. I would have thought bent rods would be an engine siezer.

I woulda towed it home, just in case the engine was still good and to prevent bits and pieces, or more of it being sucked into it.

Hopefully it was just the turbo

Think I may have got off lightly. All cylinders read circa 10 bar on a compression test so gasket,valves, pistons okay.

Ive removed the turbo. the turbine blades are sound but the wheel is hanging out the housing so I guess the internals are totaly FUBAR. The oil smoke exiting the exhaust is due to leaking through the turbo and it also looks like oil is seeping between the bearing and and turbine housing explaining the smoke in the engine bay.

Luckily the oil pool in the intercooler seems to have made a nice shrapnel filter for the shredded turbo.

With a bit of luck I can bolt on a GT3071R as a replacement and get back on the road no probs.

hopefully a lucky escape and lesson learnt then?

[adam g]

Defo lesson learnt, Ill invest in a rolling road remap as soon as the new blower is on. Doubt I'll get that lucky again.
