Just bought an 88 Jimmy knowing it had thrown a rod. Got it home and pulled the engine which revealed an oil pan full of coolant and three broken rods. I haven't torn it down yet, just removed the oil pan to see the carnage, but I assume there is at least one hole in a cylinder wall. I have no experience with damage this bad. Can I put a sleeve in the damaged cylinders? If so, is that a quality fix or will I regret it later? I want this engine to last a Long time. Any knowledgeable replies would be greatly appreciated.
