There's gas coming out in the coolant expansion tank of my car. The mechanic said the head is pushing compression into the coolant. He said the engine needs rebuilding. The car runs and drives, but as a precaution I'm not using it right now. I await comments from experienced people on the forum. What could the cause be, or if there's a solid mechanic you can point me to. I live in Didim, Aydın. But I can travel to nearby provinces.

4 repliesIt's the head gasket - the compression the pistons produce might be leaking into the coolant line, or there could be warping directly in the cylinder head or block. You can't say anything for certain without opening it up.
Translated from TurkishWhy would you need an engine rebuild? The cylinder head gasket will need to be replaced
Translated from TurkishI think it makes sense not to drive it right now. Change the gasket, and if there's still knocking, overheating, etc. afterward, then you can look into it further.
Translated from TurkishThey said it could be the EGR cooler, I tried that myself but the fault turned out not to be the EGR cooler. It looks like it's probably the head gasket, but do you think I can fix this myself? What should I watch out for during the process?
