Thank you guys for your response. The car had a code, p0410 the air pump cannot blow air through the heads. It was extremely clogged, thats why I removed the heads. Plus I had the oil in expansion tank. And my timing chain was making a noise, car have a 190 miles. When I removed front cover there was two coolant O-rings, one ring expanded and went into the engine head and got stuck. Thats were the coolant leak, but the head gasket was ok.
