Turbo Leaking Antifreeze?

[88 EA82T]

I need some assistance/advice from those of you more experienced in turbos than I am... 1988 GL10 Wagon AWD MT 1.8L Turbo (obviously)

 

It looks like I am leaking coolant inside the turbo and it is coming out on the flange that connects to the exhaust pipe. You can see the white dried up stuff on the flange and where the waste gate actuator connects. I cannot see any white dried up stuff on either of the exhaust headers where they connect to the heads so hopefully it is not leaking at the headgaskets or from the heads. So I am guessing that the coolant is leaking in the turbo and getting blown into the exhaust then burning off. My coolant reservoir looses maybe a 1/4" of inch every couple of days and I do not have any other coolant leaks on the car. The oil on the dipstick looks like oil too.

 

So does it sound like it is just the turbo leaking coolant? Anything else I should check out?

One of the lines on the turbo is a coolant line, make sure its tight.

If its tight and still leaking, remove the bolt and check to see if there a copper gasket on both sides of the fitting.

Also make sure the hose clamps are tight.

Have you checked your radiator for oil? Another sign of a head gasket problem. You get any smell in your car? Stem from under the hood? If it's leaving white stuff, that means it's burning off, so it should make some sort of "smoke" or at least a sign of something happening.

 

Have you tired revving the engine while looking at the turbo to see if anything is pouring out of it? That's what I had to do to determine my leak.

 

Like turbone said, make sure ALL the hose clamps are tight. I was leaking out of a loose hose clamp as well...

Well, I just replaced the coolant line in the picture on the bottom of the turbo which wasn't fun since I had to remove the turbo to get to it. I am sure all of the coolant lines are tight and not leaking so I am thinking it is something internal to the exhaust and/or the turbo.

 

My antifreeze looks green but I did just put a gallon in to top it off after the coolant line on the turbo split and I replaced it. I think my overflow bottle has gone down about 1/4" from full in the last 100 miles or so. If I do have a leak it is a pretty small one right now. I did see some brown sticky stuff on the radiator cap when I topped off the radiator. I am not smelling burning antifreeze in the car or out of the car.

 

Maybe it smokes a bit as car warms up? I was just chalking that up to cold mornings but maybe there is more to it?

 

What would the antifreeze look like if it had oil in it?
