I keep hearing of the bore's on the 1.7 can fail even at 60,000. Are these special sleeves, and can they be replaced, and what sort of cost?. Is this a common fault? Was there another similar powered engine that was used (1.6?) and is it more reliable? As the engines were sent to Japan and Spain to have the Nickasil liners done, is there a code number or something that tells you where they were done and is one plant's liners more reliable?
Sorry for being a techy, but I don't want to waste money.

I think some early ones went but I wouldn't say it's a common fault. It is said that some 'cleaning' products you add to your fuel can damage it too (redex etc.).

The 1.6 doesn't have a nikasil lining.

I don't think re-lining is possible; if it is then it's probably not economically viable.

Has anyone got a 1.6, and what do they think of the engine? I haven't seen any for sale, is it sold as a particular model, ie Thunder or something?

No particular model, there was a few 1.6 Thunders made from what we know, but most were just 1.6 which were introduced late in the production.

The idea behind Nikasil was to eliminate the need for bore liners as the 1.7 VCT motor is a bored-out 1.4 and so has thinner walls. By using Nikasil to plate the bores they did not need to further bore the block to fit liners, increasing it's strength.

The integrity of the Nikasil plating seems to be a bit of a sticky subject though it's fair to say only a small minority of engines have ever had a problem. Most cars that have had the problem have now been repaired. A good rule seems to be quality oil topped up religiously, servicing on time and avoiding very short journeys..and of course not thrashing the engine until the oil (NOT the coolant) is warm.

Bear in mind that the earliest Pumas are now approaching 10 years old, are generally driven with enthusiasm so engine wear is expected- quite apart from the fact Nikasil has been used.

it appears that the engines done at the Spanish plant should in theory have higher quality control. One of the reasons to pull the lining to Spain from Japan. So say a late 1999 onwards engine is less likely to suffer failure as it was done in Spain again in theory. though by far the biggest killer of the 1.7 engine is lack of oil! In December approx 4 engines went on this site (oil!)

Thanks for the info, What about the 1.6, I see from the performance fiqures that its not as quick, but is at as nice to drive?

[happy-kat]

it is a Puma, but there is no VCT. So may be a little dull engine wise in comparrison to the 1.7

but that also means it has more tuning options off the shelf and there is not VCT to remove/bypass if going for more serious tuning

probably more friendly to being oil starved too

Is the 1.6 puma engine the same as the 1.6 in a mk5 fiesta zetec s

99.9% sure it is
