1999 wrx. I bought in perfect running condition with a few mods, I just swapped the intercooler, turbo and manifold back to standard items. I noticed lots white smoke and, lots of brown sludge ( water / oil mixed together) throughout the intercooler and in the sump after running it for a couple mins.

I thought the turbo seals were gone, ( as i know the head gaskets etc are in good condition) so i swapped that over for another standard one, which I have previously seen working perfect.

I just put in fresh oil / filter and started filling the coolant back up (with no intercooler on) and noticed immediately that coolant is coming out of the turbo hose where it connects to the intercooler piping.

any ideas, as to where the problem lies?
