In the middle of some engine jobs, thought I would do the head gasket whilst I had the belt off. My car is, via log book and was sold as, a 1.4. However the cylinder head and induction manifold has 1.6 stamped on it, plus putting the head codes into google throws up 1.6 a few times. The gear box code also shows 1.6 in 2 results. There are no stickers (which from searching looks the way to tell) left on the block for me to confirm. I need to try and confirm its not just the head that's been changed.

Is it even legal for the used car place I brought it from not to disclose this? Basically I have been driving with invalid insurance for the last 6 months.

put your VIN in here and it should give you the engine size http://www.etis.ford.com/vehicleRegSelector.do

Sometimes different engine capacities share the same parts, the 1.4 may just be a 1.6 with a smaller bore or shorter stroke, with almost all the parts being identical

could be an engine replacement on the other side of it, so check with the DVLA what there records show, as a replaced engine should have been registered with them...

1.4 and 1.6 100bhp share the same parts the ti vct is totally different so wouldnt fit but the standatd 1.6 is the same engine as foca says the gearbox has been the same since 1999 all focis under 2.0 petrol use an ib5 gearbox

Ok, so I checked the vin and it shows a 1.4. The block has 1.6 stamped on it and the engine code is 4m5g xxxx KA. Is this a coincidence or has this had a 1.6 KA engine installed?

Edit: should have read the above properly, so it's likely a 1.6 (hence the stamp) but with smaller bore and stroke. Right?

Oh, also, the head looked like !Removed!, there was what looked like the remains of a valve right next to an exhuast valve seat and a crack... My friend pointed me in the direction of another friend who had a full 1.6 head with 3 month gurantee for a bargain £70 so though may aswell. As my old head was a 1.6, if it turns out it is a 1.4 block still, this should fit straight on right... Or do I need to put in a cancel call? Would cams be different etc

If it was a KA 1.6 it would only be an 8 valve engine.

When the engine was made its likely the 1.4s and the 1.6s were made at the same time on the same production line, and shared many (probably most) parts

Instead of designing 2 different engines, to save money/ production costs 1 engine is designed (eg the 1.6L) it uses the same tooling etc even the block castiing may be the same, and "sleeve liners" installed and smaller pistons (smaller bore to make the 1.6 into a 1.4) and/ or the crank pin is repositioned to give a smaller stroke, and perhaps the top of the block machined down

The outside of the engines (1.6/ 1.4) may look identical, (the blocks/ heads may be cast in the same mould), all the ancillaries may be identical (like the inlet manifold) and may have the same part numbers

Ford have done this for many years

the gearboxes may be identical too

many manufacturers do this, and share engines with other manufacturers, to save money, there are many examples of this

Nowadays the same capacity engine may have different power outputs (eg - 90, 100 and 109 PS 1.6L Fords, but they are also shared with PSA - Citroen/ Pugs etc ) these engines are often identical, but with different maps, or small changes like injectors etc

Some forums have resident geeks that could tell you the exact parts that will fit, the place it was made, etc etc, i cant help you because its not a Mondeo... :(

Watch out for conflicting information if you google it

Great post, very insightful, thanks.

I was a little bit excited I actually had 1.6litres hiding under the hood! Ha

Cool, well I'm going to presume this 1.6 head is going to do the job then.
