2000 B5 Audi A4 1.8T Quattro Ongoing Coolant Leak
 

Hey guys,

I've been having a coolant problem for a while now and have gone through many steps. It all started when I went GIAC stage 1. I would notice a significant loss of power, as in the turbo not kicking in whatsoever, and after much thought and diagnosis, I found that coolant was leaking into the turbo, then eventually would come out as white, throat burning, smoke out the exhaust. It's not oil because it's not blue nor does it smell sweet. So I changed the Turbo. Right before that I had a coolant leak from the coolant temp. sensor, which I changed, and one of the coolant lines that I just used a clamp to repair. I still see the white smoke come out the back only when I start the car though, it's not there while I'm driving. My guess is the heat expands the area and seals the leak then when I turn off the car it leaks. A local Audi/VW technician told me that the coolant was leaking into my oil cooler. Was just wondering if anyone has gone through any of this and if you guys would have any ideas as to what path I should take next. :confused:

PS. I've already done a compression test and everything seems fine right at a consistent 150 PSI each cylinder.

Thanks in advance! :)
