Hi all, I've Got a mk3 fiesta Si with a 2 litre mondeo zetec e engine in, I've just rebuilt her. But the oil consumption is very high every once a week I'm putting at least half a litre in.

I've checked every gasket and seal, has new rings and bearings the block has been honed out aswell. There are no leaks what so ever,

It's baffling me to no were it's going to. Any help, please would be great fully appreciated. Thanks sean
