I have a 01 fabia classic which has just had an engine replacement from another crashed 01 fabia, there was no mayonnaise oil on the replacement engine ie oil cap was clean, now i'mm losing coolant at a rate of half a litre every 100 miles, is there something that may have been overlooked in the engine replacement and how do i solve the oil problem, where is the water getting in? any help appreciated

Sounds like headgasket is gone / going

yea head gasket

thank you, in the meantime i got in touch with the guy who changed the engine and he said the same, one more thing the connection points for the rear washer, the motor whines but no fluid emerges, there was a link for the connection points of the rear washer but it is no longer available

At the bulk head near ABS pump, under trim rear passenger side by seat (leads to wet carpet), and also possibly inside the tailgate itself.
