As I understand it Japanese emission standards are so tight that engines are replaced because of normal wear long before they would be considered unserviceable here. I would put a new timing belt and water pump on before putting the engine in a car, though. It's got to be easier to do on a stand, and then the new owner knows when it is due again. Mike |

Re: Buying a replacement engine
I just looked over the threads of this saga the OP began
earlier this year. Yikes. With all the other reports of head gasket (or block or head etc.) failures, especially those reported in summer time, I wonder if the newsgroup will continue to see repeat failures resulting in the need for a replacement engine. Granted this is happening overwhelmingly in older Hondas, c. 1988-1993, so it's hard to say if it's due to an imperfect repair job; extraordinary summer heat; or simply the age of these older Hondas. |

Re: Buying a replacement engine
Jim,
Not trying to jack this thread. But I have a question. Why does automotive engine usage get measured in miles/kms and any other heavy duty application get measured in hours? Wouldn't these engines from Japan have crazy high hours? I was speaking with a farmer the other day, and he shed some good light on the whole oil change thing.... He said John Deere recommends an oil change every 300-400 hours. If I translate that length of time into KMs in my car, assuming my average speed is around 50km/h, (I do alot of highway miles) that would mean that 300 hours is 15000kms? For the record, I change every 5000kms. But why the discrepancy? I buy heavy duty diesel engines for a living. I don't maintain them for a living though... otherwise I would know Cummins' intervals for oil changes. But I do happen to know on the design side that oil filtration is really no different on these heavy duty applications than on the average consumer vehicle.
