Thread: Loosing coolant?

Ok so I used that combustion leak tester kit today and the dye remained blue telling me it's not the head gasket.

However, I did some revving and watching what comes out the exhaust. Some water and white smoke is coming out, a little more as the the RPM's are higher. So if it's not the head gasket, what about the turbo seals? would it be time for a rebuild? thoughts?

How does the test kit work??

I posted a link to it in a previous post.

With the car running an water hot, the test tube is fitted to the filer neck and contained inside is a blue liquid. squeezing an aspirator bulb attached to it sucks up any air in the system, including possible exhaust gas. if the liquid turns yellow, exhaust gas is present in the cooling system, hence a head gasket leak.

Also I just thought my turbo is ball bearing. Are BB turbos rebuildable?

Just curious were did you get the kit. Your hg may only leak under boost .

Stratton.

It has to be leaking all the time because I was revving while parked. no load. but yet the kit didn't return yellow fluid. aww man this is stressful.

and BB turbos aren't rebuildable as i just found out so I guess it can't be the turbo that's leaking.

Pressure test.....

what else would cause water to get into the exhaust besides a head gasket?

The combustion process.

If the leak is small, like yours, it is possible that the kit may not be able to detect it. Also any minute amount of exhaust gas in the sytem may not make it all the way to the filler neck on the radiator...it may get caught in a high spot in the cooling system.



Just because they are not rebuildable does not mean they can't leak. All that means is that you can't repair it and you have to get a new one!

Did you pull the spark plugs yet and see if one is cleaner looking than the others? Please do that and report back.

Was the car warmed up at this point? White smoke can come from running rich, like at start up. The water in the exhaust is normal especially at start up. When the car has been warmed up it just evaporates. Is it really heavy like you can see in your rear view mirror when you are driving?
