Hi..

 

Hopefully i can help..

 

Depends if the second hand engine is like for like as the old one it would be pretty hard to spot costmetically.unless there is documentation/paper trail saying as such the engine been replaced,what mileage the replacement engine had and at what mileage it was replaced in this car.if reconditioned.new then it should have a warranty...also engine number on the engine in the car doesnt match that on the cars v5c or exsisting engine number..I do hope this helps..if you need to ask anything else or include anything further then just continue before you rate

Hi,


What does v5c mean? How can a lay person match the engine no. with v5c or existing engine no.

Expert:  Robert replied 3 years ago.

Hi..there thanks for your reply..

 

v5c in the uk is yours cars log book - the engine number will be in the log book

the engine number will be on the engine block..if your requesting a mechanic to check this out then he should just have to locate the number and see if it matches that of the log book..if not then the engine has likely been replaced..I do hope this helps further
