Big Ben Posted February 11, 2014 Share Posted February 11, 2014 Turbo is bad. There is no restrictor for the coolant lines. Quote Link to comment Share on other sites More sharing options...
Big Ben Posted February 11, 2014 Share Posted February 11, 2014 Did you check for any shaft play in the turbo? Should be rebuildable pending its not ball bearing, the wheels arent damaged and the shaft play isnt significant. Quote Link to comment Share on other sites More sharing options...
logr Posted February 12, 2014 Share Posted February 12, 2014 Is that even possible? I'm thinking the water is going around the turbo center section but there is no way for it to get into the exhaust from there. It's not like the oil where seals seal it around the shaft. Better check the head gasket. Quote Link to comment Share on other sites More sharing options...
Big Ben Posted February 18, 2014 Share Posted February 18, 2014 Now that you say that, I dont think I have ever seen anyone have coolant in their exhaust due to a turbo seal. I have been around the SR game since the late 90's and nothing rings a bell. However if he just did a turbo swap and it was fine before, and it leaks now then maybe there is a leak from the turbo. I would assume the coolant ports are cast into the CHRA, maybe there is a possible crack, but you would think there would be oil contamination. Here is a good rebuild thread with an exploded view. http://www.driftworks.com/forum/technical/60665-how-rebuild-your-t28-turbo.html Quote Link to comment Share on other sites More sharing options...
