Bore and ring wear still happens!
Its just generally too expensive to sort it that has made it disappear from the jobsheets!

Worn rings are unlikely nowadays with modern engines/lubricants.
If you have broken rings then the engine will be damaged big time.
A smoky engine is more likely to be caused by worn valve seals.

I know on these Zetec-SE engines you're definitely not supposed to disturb the main bearing cap/ladder assembly. Ford don't even provide torque wrench settings for the bolts.
I thought the rods were okay, as long as you keep the corresponding cap with the right rod.
Smokiness could also be a breather fault.

Thanks for your comments!

Hi,
The reason I think it needs new rings(certainly oil control rings)is because they have lost their tension or spring and sit level with the sides of the piston.

So you already have the pistons out then. I assume this engine has been overheated to soften the rings so a replacement short block is your way forward and a head skim and rebuild. Regards Peter

I presume they do a recon short motor for this ( i have not checked!) if you build it exactly the same way as the engineering companies do i can't see a problem?
Somebody somewhere built the new one why can't you recon the old one the same way?

It's a 1.6 so aluminium block. So not reborable...
and Ford do state you cannot repeat cannot rebuild the bottom end.
Usually a reason..:-)

If the bore's are in spec there is no need to rebore and fit oversize pistons.
Im sure somebody will put me right why not?
But like i say if it is built up exactly like the original build in the same way what's the difference?
usually a reason, what's the reason?
Screwloose have you any idea's?
Got me very interested as this post!

I've never bothered. Ford say that the block distorts as the mains are released - that seems to be borne out by the few that have tried.
If you can't remove the crank, then you can't regrind the big-end journals - so what's the point of going there at all?
I cannot believe that the oil-control rings are flush with the piston unless they are stuck solid - they should be nearly falling off the piston, worn or not. If they're that worn, then something was seriously wrong with the lubrication, the bores will be oval and this one is history.....
The usual reason for oil consumption on this engine is the rings not bedding-in due to running-in on fully-synth. Fitting a complete new Ford unit has cured it on every one I've seen. There must be plenty of good second-hand units around now, as they either drink oil or are perfect.

I had the block/crank/pistons 'short block' assembly replaced on my 2001 1.6 (manual) - at 90k it was using a gallon of oil in 2000 miles. This was *not* cheap - I think replacing the whole engine with a second hand unit would be far more economical as it's far less work to swap the whole unit than essentially rebuilding the engine.
I am a bit concerned that Honest John's car-by-car makes no mention of problems with the 1.6 Zetec-SE engine, I am certainly not the only person to have had similar problems. Between the garage that did the work on my car, a Ford specialist I spoke to and the focus owners club, it seems there have been plenty of 1.6s suffering from high oil consumption.
I'm just waiting for the 'what next' now - might place a sweepstake on suspension or gearbox needing attention first! Had a new exhaust manifold and power steering pump since the engine was done too...

£750.00 for a brand new 16v lump on e bay in the crate! they will deliver for extra.
Plenty of second hand lumps about through the country.
It's a shame it can't be fixed but if thats it then get your wallet out!

Just out of interest; did your engine drink it from new [a ring bedding-in issue] or did it's thirst develop slowly from wear? Nearly every one that I've seen drank it from new - two were run bone-dry by careless girls. ["Stupid car's got a yellow light on; does it mean anything...."]
These seem to be chalk-or-cheese; using excessive amounts of oil - or none at all. Ford were using a fully synth 0W-30 when the problem first appeared on the Zetec S - whatever happened to that....?
