on the receipt for the wrk it says its a 2litre mondeo engine thats been bored out to accept the cvh head with modified pistons,
So i'm pretty sure its a zetec bottom end from a mondeo and the dipstick is at the back
it wrks fine aswell (monitoring oil level) could the zetec bottom end be modded to accept it at the back or are there versions of the zetec that have it at the back?
