Joey Joe Posted January 8, 2007 Share Posted January 8, 2007 I am diving into a head gasket replacement..... coolant leaving the system, over heating, oil and water are mixing in both systems and I have bubbles coming out the coolant over flow tank, and water in the oil, Oh yeah this engine has less than 70k original miles, so I have cold feet about this head gasket diagnosis. When I pulled the turbo to intake section off there was tons of milky coolant water around the edges(meaning coolant is going right into the intake through the turbo?). It may be a side effect of the blown head gasket (since the turbo runs off exhaust) but I do not know how the turbo relates to the engine, it seems weird that their would be a lot of dirty coolant and water in the turbo to intake pipe. I have not had this sympyom before, and I have done a head gasket. I am wondering if this could be an internal turbo problem, and not a head gasket????? My question is, is it normal for coolant and oil to be in the turbo to intake section when their is a head gasket blown, or does this maybe sugest that the turbo is f'ed.

idosubaru Posted January 8, 2007 Share Posted January 8, 2007 this is on the loyale turbo in your profile or something else? being a later model turbo i think you have coolant and oil lines going to your turbo, they could be mixing there at the turbo. i'm not very familiar with turbo's, but they can blow seals and leak oil and coolant and i'm guessing it could mix? sounds like headgaskets though, have you tried a compression test?

Turbone Posted January 9, 2007 Share Posted January 9, 2007 You have the worst case scenario for a blown HG. I would have the heads decked a little too, I would bet they are a tad warped. Link to comment Share on other sites More sharing options...
