Which of two identical cars would you consider to be worth more, A car with 100K with original motor or a car with 100K which had the motor rebuilt at 80K? I have my own ideas but I'm just curious what the rest of the world thinks. |

Replying to: oldfarmer50 (Jan 10, 2009 9:47 am) Rebuilts have their own risk after all----who did the rebuild, did they disturb various parts of the car, etc. Rebuilts also bring up doubts ----what's with these engines that they need rebuilding in 80K miles? So the "advantage' of the rebuilt is offset by the unmolested qualities of an original untouched motor. EXCEPTION: If it were 200K on a car with original engine, versus a rebuilt motor at 180K, I might think differently, but even there, the value would not be all that much. |

Replying to: grandtotal (Jan 11, 2009 6:42 am) With an engine that has 80K on it what are the odds that it was something like that over neglect or abuse? I would suspect that for every one that was caused by a bad timing belt or something similar there are a multitude that was caused by never changing the oil or something similar. That being said I agree that I would shy away from the rebuilt simply because at 80K miles there should be no reason for a rebuild.

Replying to: snakeweasel (Jan 11, 2009 6:55 am) I'd hazard a guess that about 90% of all engines advertised as "rebuilt" are not in fact 'rebuilt" at all. REBUILT should mean that every part of that engine has been re-machined, or replaced, to meet exact factory specs. OVERHAULED means that the bad parts were replaced and the still good parts left alone. For example, new valves, rings and bearing, but crankshaft and camshaft remain the same, untouched, as do cylinder walls, oil pump, etc. REPAIRED or UPPER END WORK is when you throw a timing belt and so they level the cylinder head, insert new valves and guides, put on a gasket and a new belt and change the oil. That is certainly not "rebuilt". It costs at least $5,000 to rebuild and install an engine in a modern car, if you do everything you are supposed to and take care of the 'as long as you're in there' parts as well....new belts,hoses, clutch, water pump, radiator, blah blah. I can't tell you how many times I see a car with a "rebuilt engine", and ask to see the receipts for it, only to find a repair order that says, in one line "remove engine, rebuild, re-install same" Tells me nothing. Sometimes the cost of the work is a hint but still no details. That is a shabby shop if you ask me. So what is this "rebuilt" engine. There is a vast difference between a factory long block installed by a dealer and some vague "rebuild engine" repair order from a Conoco station.

Replying to: Mr_Shiftright (Jan 11, 2009 8:46 am) "New engine" is another phrase that, (to a lesser extent), is sometimes used rather loosely. It often translates to: "newer used engine with undocumented mileage and maintenance history".
