Probably head gasket, all to common  on these

Shh! My daughter has an 1100cc Seicento that steadily looses water .......

Thanks Mark, I hadn't really considered that. Although the water level is good, the oil is not milky and it doesn't smoke like Dot Cotton. When the weather improves, I'll compression test it.

They usually either fail between cylinders or water jacket to bore, the result is a very small amount of coolant leaked leaking into the bore when they are sat for a period resulting in amiss fire on starting which clears.

We couldn't find the cause on the one my sister had. A car with no redeeming features, she would have been better off with a clit!

I finally got some time for a more extensive poke.

Compression test came back even but quite low. Circa 65psi on all four. I will check if this is norm. This is the first time I've used this compression tester after my last one went AWOL.

I tried the old school trick (suggested by someone else) of a long screwdriver on the injector and my ear on the other side. 1&4 were clear and loud, 2&3 noticeably quieter, if there at all. So with the engine running, I unplugged injector 2, no difference to the engine tone. Reconnected and did the same to injector 3, again no difference in engine tone. I am now suspecting both of these are beginning to fail. How this has manifested its self as a coil pack fault, I still haven't worked out.

My next action is to connect the spare injectors I have to the loom only and have a listen to them, to make sure they work. If so then it's strip down time.

At this point my phone rang, my mate was sat on industrial estate with a glowing brake disc. Deviator breakdown services get called out once again  I will update when I make more progress.

Thanks for the ideas.

Often if an ECU detects a misfire on a cylinder due to HT issues it'll shut down injectors on affected cylinders to protect the catalyst from unburnt fuel ingress.

Something I wasn't aware of, thanks! I'm going to connect up my spare injectors to the loom only and hopefully these will click better and give me some reassurance, although maybe not from what you are saying!

Have you access to a code reader than can show live data ?,it would help your diagnosis to see what's happening real time

It is not a crap engine - It's very, very good. (for what it is).  Easy to work on and extremely reliable.

The Seicento Sporting is a really lively little thing to drive.  I wouldn't like to crash one, but in terms of hammering around country lanes and such, it is a belter.  Far better than a modern Fiat 500, Ford Ka, Vauxhall Adam etc.

It's easy to work on, but reliable? They're like V6s, I've yet to see one that doesn't have an oil leak which leads to oil starvation and all the nasty things that causes. Oh, and overheated ones are very common.


And the handling? Lift-off oversteer at 30mph? No. Just no. Very, very unpleasant.

We all have different experience - I am yet to see one with an oil leak.

Lift off oversteer at 30mph?  Learn to drive

I'm a serial Capri owner so correcting it was a natural reaction, but having to do it at low speed in a FWD car  after a gentle throttling off approaching a roundabout was an unpleasant surprise. So much so that I had to stop and check the tyre pressures. It does that was my sister's reaction when I returned her car. So have the others I've had the misfortune to drive.

Oil leaks from the cam-cover and head gaskets are normal. And rusty sumps are so common that factors used to keep them in stock.

I've seen several where the engine and gearbox had fallen out.

I managed to adjust the door fit on a hired one by racing another down a beach road. Kate wasn't happy; she had to throw herself against the door to get it open

They are so shit I'd rather have a clit

[Andy B]

My daughter's Seicento has an oily rocker cover and the sump is rusty. Can't say I've experienced oversteer though, but I rarely drive it.
