Reman or used engine. You can rebuild the lower end of the engine, but it seems like an engine that has cancer. That is, shortly after doing the lower end, the upper starts with problems. Just from what I have seen. Would appreciate any info anyone else has.

The best bet is usually a used engine for cost effectivness and down time concerns. Not much rebuilding happening at the dealership level, even for warranty repairs.

The reason for rod knock is there is play where the connecting rod Jonie's piston. Or play where the rod connects to crankshaft. this usually results from a constant lack of engine oil. this is when wear between rod and piston, and/or rod and crankshaft will occure. the only way to permanently fix is to machine the rod that is worn, basically taking apart most of the engine. try using a high viscosity oil with an additive. this will fill in the wear , and maybe you will be OK.

What is a bearing knock?

A bearing knock, or a rod knock develops when the bearings between the rod and crankshaft wear, leaving a gap, allowing the crankshaft to slap the connecting rod. The knock develops slow for a few miles but once the rod starts to knock then the gap increases because the metal in the rod and the crankshaft get destroyed and deteriorated. As the gap increases the knock gets worse, and as the gap increases the knock and the damage will rapidly get worse. Within a short while the connecting rod will break open and get stuck between the crank and the engine block, possibly cracking the block and destroying the crankshaft. The engine is now inoperable :< To prevent the rod knock, let your engine warm for a minute or so before driving to ensure the engine oil has been pumped throughout the engine, and get regular oil changes, because a thin film of oil is all that separates these engine parts, and dirty oil will be squeezed between the metal parts, increasing the rate of erosion. .
