1994 Suzuki Escudo 4 cyl Four Wheel Drive Automatic 150, 00 miles
The engine rattles on acceleration- the sound is similar to rolling your tongue. The previous owner drove it to overheating, blowing the head gasket and making a hole in the water jacket, allowing oil and coolant to mix. He drove it in this condition as well, but I have since had it repaired. The mechanic thinks the rattling is due to defective bearings. How can I be sure this is the problem, before paying him to take the engine apart?
