My Mk4 2.3 petrol auto mondeo now has a hole in no4 piston. As I like this car and want to repair it I was looking at having the engine reconned, but I worry about the caveats in the advertisers script. We think the bore is heavily scored so the rebuild would have to include new liners so that will be more money. You have to send them the engine first to examine it, then they decide if they can do it for £1095.00 plus the vodka and tonic.

We tried Ford for a new short engine, but they said "These are very rare so no discounts, full retail price and need the old engine in exchange" I recon they want me to buy a new Mondeo, so are putting me off with high prices.

I have an idea that the Mazda 6 L3 2.3 petrol engine is a very similar lump, and as there seems to be a good supply of these I would not mind fitting it. There are a few used ones listed for £400.00-£800.00 and just need to know whether they will mate up ok.

Can anyone help or do I scrap a £4k mondy??

Well it certainly surprised me that there are not any 2.3 duratec petrol engines around. Plenty of the old type for the Mk3 mondeo and earlier, but not Mk4.

Now I know that the Ford duratec (world)engine is made in Mexico and is a Mazda, which Mazda have ceased production of (see Wikipedia). As there lots of Mazda engines about 2.3's at that, my question was can I swap out my dead engine block with one of these and then rebuild.

I am told the the no4 pot on my duratec is badly scored and would not rebore, if anyone could do it and get oversized pistons and rings. They just don't do it. Best is reline then put standard piston and rings in.

Maybe in a few years there may be engines or maybe they will all be dead like mine

Well I spoke to a guy on Friday who had attempted putting a similar engine in a car to save same and he said although it did work, there were always other issues, as it never worked like the original. His advice was sell as salvage with a blown engine, so that is what I plan to do.

I am taking my personal reg off it, draining the 3/4 fuel tank into my 306 and cutting my losses. Sad but practical, as I do still have a ecoboost Focus for my everyday ride but that's a manual 6 speed and I have to stir the pot.

So I'll put on here and Ebay asking for offers 2007 Mk4 2.3 Mondeo Zetec, rare saloon car (not hatchback) 116k miles, 2 owners good condition MOT Sept 15

Well I have decided to fix it! Been a long journey

Went to scrap it using Charles Trent, they offered me £500.00 for the car. I accepted it then I had a call saying is it complete? I replied that we had dismantled the engine to see what was wrong with it. The girl then said, "Well as it is not complete we can only give you £200.00". I told her to ps off.

Ordered a new short engine and other bits from Ford Parts UK and it should be rebuilt by the end of this week. They were very quick, took 3 days but I had to collect from Salisbury.

You can't get a Mondeo petrol auto now they're all diesels.

Ok so it has cost a few bob but I got my mobile armchair back

When I first bought this car there were issues with the engine, which is why it was cheap. I did think we could resolve these issues, crank sensor, lambda etc and I would get away with it. But I now think the damage had already been done. A little bit of extra stress finally made its mark. When I get the old short engine back I will take photos to show the damage. Apparrently there are many pin holes in No4 and some smaller ones in No1.

When the rebuilt engine is complete I will have full diags run on it to make sure all is ok. I do not intend to scrap a virtually new engine.

Well it's all sorted now, purrs like a cat and drives like it should.

The dealer's mechanic used a bolt instead of the correct timing pins (cheap skate). My first mechanic fitted a new crank sensor, but never checked the timing duh!! The rebuild mechanic set it all up properly and now I have the car I wanted.

In future if I buy a car like this (cheap from a dodgy dealer)I will take it to Dennis and get it checked over properly, to save all the agro

I part exchanged mine 2 years ago as it developed an electrical fault(s). We couln't stop the cooling fan coming on and the gearbox developed a mind of its own.

I partexed for a Nissan Leaf 40KW and have never looked back. Only do petrol now for old british motorbikes
