So now you need to determine if the misfire is mechanical ( base engine fault ) or ignition/fuel
Can you borrow an compression tester ?

Since the main fault codes were misfire 2 and 3, I swapped the coil packs around so now in the order 2,1,4,3 and started the car. Cleared all codes and took it for a drive. It drove well but this rattle was really noticeable and not just at idle. After the drive there was no fault codes at all. It idled steady at 750rpm for a while and then started to get missy again but rattle was there all the time. The rattle sounds like a stick being pulled across a railings - click, click, click. I am beginning to think I may have a stuck tappet or cam follower type problem. Is this likely or am I completely on the wrong track?
The oil appears to be getting thrown out in a very fine spray from around the rocker cover area and looks as if it is also coming from in under the plastic tray that the coil packs sit into. Oil is only noticeable towards front of the engine.
Hopefully on Saturday I will be able to get it indoors and get it on a jack to have a look and see if I can determine location of rattle.

Have you got a pressure gauge to test the fuel supply to the engine? If not, might be worth fitting a new filter anyway, then run a hacksaw through the old one to see what the missus has managed to vacuum out of the bottom of the tank.

Had another look today and after driving it had thrown oil out from what looks like the oil filler cap which has a large rubber seal around it. It also looks to be coming from around the rocker cover area. Still misfiring and rattle really noticeable for about 30 minutes but then seemed to disappear which I can't explain except going back to my original comment about a stuck tappet or something like that which has freed itself. Fault codes after drive were misfire on 2 and 3.
There seems to be too much pressure in the rocker cover. No oil being thrown out through dip stick. I was wondering if the big breather box at back of engine could be blocked and creating pressure through the engine which is being released via the rocker cover. Does anyone know if these give trouble. It is the BCA engine. A mechanic friend hopes to compression test it for me on Tuesday.
I don't have fuel pressure testing equipment either. A fuel filter was never changed on the car but I now know the engine light flashing occurred a few days before it was let run low on petrol so I am happy to discount this as the problem.

You realy must check compression at this stage, it will tell a lot. Does it blow back at oil cap when removed? Still sounds like what I said before. Hope it's something else

Hope it's something else Hope to get compression done tomorrow which I agree will tell a lot. It doesn't seem to blow back when you have the cap removed but it does seem to be a bit smokey from around that area when you rev it. I'm not sure if it is the smoke is the oil that is around the area being burnt off the exhaust manifold cover. There is definitely oil around the coil pack areas but not down in the plugs wells. Will advise the results of the compression test once done. Doing some research on line and it appears that the breather box at back of engine does block so that may also be a problem or I'm wishful thinking.

Blocked exhaust system?

I got the compression test done and was told cylinder 1 and 4 were reading 120 and 2,3 cyclinders >200. My worse fears have been confirmed. Absolutely gutted that this has happened to such a good car. My father who is a retired mechanic owned this car from new and it was always serviced on the button and the oil and filter changed every 6000 miles. Since my wife has had it the same has applied. It sailed through the NCT in Sept this year. The mechanic that checked the compression said he cannot explain why this has happened but believes she got bad fuel at some stage and mentioned that there is a huge issue in Ireland at present with petrol stretching using kerosene and he has heard of engine failures all because of this. He suspects that rings have broken up.
We are now looking at second hand engine as I guess this would be more economically than a rebuild but am told that I may struggle to get a decent 1.4 petrol BCA engine. Appreciate any thoughts and thanks for the replies so far.

Just did a google search on this kerosene issue and the problem appears quite widespread and the symptoms described are text book to what I have had - low knocking sound, misfire, excessive crankcase pressure. The problem is trying to identify where the bad fuel came from and trying to prove it. Probably a lost cause but this just sickens me.

Why don't you take the head off and see what the damage is?

As I suspected. Cheapest and best way out is remove Pistons,the rings will not be broken but stuck solid in groves, get the Pistons cleaned and fit new rings, It's difficult to get a good second hand unit for one of these . It takes a bit of time but not a very difficult job to do. Make sure the new rings are correct before fitting as I've been supplied with wrong rings before on this BCA engine seems there can be 2 types.
