hi everyone. just taken my mk1 1.6 focus for the test and its failed on emissions.havent had the car long but it has 110,000 on clock and apart from this it runs fine. i was going to service it yesterday but it rained all day so didnt get chance so not really sure when it was last done and i too it for a good 45min drive before test

anyway heres what it failed on,

1. exhaust emits excessive blue smoke during accelaration

2. (4%) exhaust emissions carbon monoxide content at idle excessive

3. (8.5%) exhaust emissions hyrocarbon content after 2nd fast idle excessive

4.(409ppm) exhaust emissions hydrocarbon content after 2nd fast idle excessive

5. (0.70)exhaust emissions lambda reading after 2nd fast idle outside specified limits

so to start im looking at putting a new cat and lambda on aswell as a good service.is there anything else i should be looking at/out for aswell?

cheers

Lambda sensors etc wouldnt control the colour of the smoke....its usually relatd to something mechanical (although they will control the emissions) Blue smoke....usually means stem seals....if not the worse case scenario is piston rings...but thats usually white smoke. Easiest way to check if its rings is to take out all plugs and check to see if they are covered in oil. If they're not then i'd say stem seals. If its not rings you could try changing sensors and putting a load of stop smoke in....however this will only temporarily fix it to help it through its mot...you will still have the underlaying problem of something mechanical

Had a feeling it'd be stem seals as per my previous post. As for standard at 100k for stem seals I think that's just chit chat. It depends how well the car has been looked after. Beforw my at I had an old 1.8 s reg focus that was on 99k and showed no signs of needing them done and never known it on any of the other zetec engine ranges.

shims need done at 100k miles mate, or atleast the clearances checked.

well ive been busy over last couple of weeks getting car ready for test.had the stem seals done aswell as new cat,lambda and a full sevice (including leads and coilpack) and today managed to get it through test.

stil had a bit of trouble though getting it through though.one minute everything was within limits next it wasnt.the main one that varied was the CO2.had a talk with the tester and he says what seems to be happening is its over fueling every now and then which keeps making the readings change so i think im going to take it into ford and get it hooked up on livedata to check that everythings running as it should but suspect it could be a faulty injector.

im sure its 70 or 80 quid to have it done but to be honest you could spend that getting parts that dont fix the problem so ide say have it checked
