engine

it must be disassembled to determine the cost. a high figure would be about 2000 and a low would be around 1500. this does not include any labor or parts required to remove/replace motor Roy

is this engine still running, if so the rebuilt will be much less since there are no broken parts other than normal wear. a standard rebuilt with out maching will give you another 100,000 plus miles, either way you are looking at least $1500 for labor plus head work and parts
