Kalle

Hey guys. Im suspecting that I have a blown coolant seal. However, I checked for bubbles coming up at the filler neck when cold starting, NO bubbles. Also checked the sparkplugs/combustion chamber afer the car had been sitting overnight, no coolant on the plugs what I could see.

On startup it does not smoke more than normal. But after 3-4 minutes when it starts getting warm the white smoke comes more and more. I was thinking it might be a leak from the turbo so that the coolant in some way enters the exhaust? Or maybe the irons just expand when they get warm and lets the coolant pass by the bad seal..

Any ideas??

Thanks

Check your coolant level, is it getting lower or staying the same. This will indicate if it's coolant or not...... You can also go to a garage that has the device to measure hydrocarbons, open the filler neck and get them to place the probe over it. If it reads levels of hydrocarbons it's an indication of exhaust gases in coolant system and most likely a blown seal.

If level doesn't change and no hydrocarbons detected, most likely oil from turbo, overfilled oil sump, leaking oil sump (allows condensation in but usually on dry days smoke stops after warm), leaky omp injector. Start with the coolant

Is the oil leaking?

Im in the same boat just got this GX with a bad coolant seal, saving up for a rebuild.

knowing which car you have might be a good place to start, then the mods it has.
