I have a 2006 Chevy Silverado 3500 6.0. Yesterday I noticed the above liquid on my driveway. I guess this is likely a head gasket leak? I wonder is this a common with GM engines. My truck only has 104,000 Kim’s. as I am in Ontario Canada. I always service regularly. I have a truck camper on it during camping season so it does work but with ease. I have it booked into my local repair shop for Monday. I was wondering if anyone had similar issue.

 

better not be common! LOL engines don't really run with head gasket leaks.

I don't know of any white or beige liquids.

Can you pop the hood and see where it's coming from?

 

Tells me water or coolant in the oil, but leaking externally?

 

Yes it was in the driveway when I popped the hood could not see any leaks. I went on YouTube and the white substance is usually coolant in the oil. The origin seems to be at the back of the engine.

 

I'd strongly recommend checking the engine oil. If the level is ok, not overfull etc. then look at the transmission, it might be a leak in the radiator cooling line, ans leaking out a seal. Also, check your coolant for oil, and low level.

 

Good point Kevinpkp Never thought of that.)

 

Thanks for all your comments guys much appreciated.
