hi just got an escort van 1.8td 2000 on an xreg did an hpi check and mot history check all good. van has 63000 miles on it. but I would like to find out if its the original engine in it... where abouts would I find the engine number on the actual engine? on the checker I did it says my engine number is YE79192 where do I find this on the van to confirm it. vin plate and all that match fine

cheers for any help guys
