s4 turbo problems,pls help
I just swapped the engine on my 88 turbo. so far I've only got it to start for about 5 to 10 seconds at a time (then it stalls) and I will have to deal with this issue too lol. My question is what causes the turbo to leak water into the exhaust? I've read so many different things and I am a bit confused oh I forgot to add that the turbo charger makes a whoosh sound every other time when attempting to start the engine.
Thanks in advance for info guys.

Are you sure it is leaking into the exhaust and not 'onto' the exhaust?... Because there are two COMPLETELY different explanations. Sometimes one can easily be mistaken for the other.
As for starting it... You need to verify that you're getting fuel, spark, and air. The AFM, CAS, water thermo sensor, atmospheric pressure sensor, and boost sensor all must be plugged in.
Does this happen to be a JDM swap? Has the engine been rebuilt??

If the coolant seal were severely blown you'd be losing more coolant than you could keep up with, and the engine would sputter upon startup then clear.up shortly after (all coolant in combustion chamber that's leaked in burning out). Itd blow out very heavy thick white smoke so badly you can't even see behind your car.

The exhaust always produces some water on startup. You have exhaust comprised of steam and CO2 running over cold metal. Steam condenses on metal and gets blown out as water. When the exhaust is warm enough, it will stop.
Rent the coolant system pressure tester from a local auto parts store just to make sure you have all your coolant connections sealed up well.

If I pour water in the radiator water comes right out the exhaust (I only have dp and silencer at the moment) .Is there a way to know for sure if anything inside is cracked for sure? The strange thing is that it really doesn't smoke, at least for the 5 seconds it stays running.
thanks

Wait, your coolant comes out the exhaust? Have you compression tested the motor?
+1 for the low miles motor being blown. Remember, if it's from a salvage car, why did it end up there in the first place?

Still, the previous owner could've trashed the car anyway before or post accident. I always assume nothing ever works unless it's up to my specs (Torqued, balanced, minimums, multimeter, etc.)
Seeming fine is not the same as actually fine. Not only that, you have coolant lines running through your turbo. You could also have a turbo seal failure.
