The numbers you're showing are just manufacture casting numbers...nothing to do with engine codes....the engine number will be usually "stamped" into the block, not cast and is usually at the right rear under the exhaust manifold and right side of the head, unless the engine has been changed or replaced, in which case the stamp pads may be blank. There's often a sticker on the timing cover too which has the four digit code...but they usually fall off or just deteriorate.
2.2 Euro-5 engine codes are as follows:
CYRA, CYRB, CYR5, CVR5, CVRA, CV24, DRRA, DRRB, DRRC, USR6, and UYR6.
The difference is whether FWD or RWD and which hp rating they are...All the FWD's are essentially physically the same....All the RWD's are eseentially physically all the same...it's just the hp rating, usually determined by the PCM firmware, which differentiates them.
RWD's are:
Ford Transit 2.2 EURO 5 RWD MK7 & MK8
Engine codes : CVR5 CVRA CYRB DRR5 UYR6

you are going to have to purchase some measuring instruments .. or just take it to an engine machine shop and trust to them to decide to rebore or hone .

That bore is done...all honing will do is make the bore oversize...there's a very small tollerance of piston to bore clearance of 0.01mm or 0.0025". There are also three classes of bore diameters and three classes of piston diameters...these must be matched properly or you'll end up back where you are now. Why bother doing it if you're not going to do it properly.

unless rebore before a hone .. the type of hones with flat stones will skip the top half of the cylinder because its resting on the unworn portion at the top as you draw it up.
that's why someone came up with this type of hone, not necessarily this actual one .. found this for illustration purposes ..only.. first one in search .. not looked at detail
https://www.ebay.co.uk/itm/397867468066?
all you can do if yours isn't one of these .. is carefully take down unworn with flap disk - i'm describing a botch that got me another 60,000

anyway the flat stone hone will show up any wear for what it is .. you'll be able to see and decide .. because the wear it will skip areas and it will stand out plain as day
