SOURCE: Catalytic Converters

You are correct. That portion of exhaust is indeed a catalytic convertor. This would be in the rear portion of the pipe with a flexible section that goes underneath the oil pan. Then you have a long muffler and a final muffler in the rear of the vehicle.

Internal oil leak, change the spark plugs and cables, oil, filter and add Lucas oil. Take the car for inspection and let me know how it goes. For the belt depends where you get the parts and who does the work.

SOURCE: my ford focus tdi 2003 cant select 1st,3rd or 5th gears.

Car is in limp in mode unless you have the tools to work on automatic transmission you will need to take it to a transmission shop. Of course you can check oil level but I suspect you have other issues.

The exhaust systems are of a two-piece construction for production and five-piece construction for service.
Catalytic Converter
The catalytic converter fitted to the Focus range resembles a small muffler. Because of the high temperatures at which the catalytic converter operates, the vehicle body areas around the catalytic converter are protected by heat shields. The catalytic converter controls three emissions; Hydro carbons (HC), carbon monoxide (CO) and oxides of nitrogen (NOx).
Catalyst deactivation due to poisoning
Sulphur (S) in the fuel can cause deactivation of the catalyst.
Lead (Pb) in fuel can cause a severe deactivation at levels above 5 mg per liter of fuel. It is therefore essential that vehicles with catalytic converters always operate on unleaded fuel.
Zinc (Zn) and phosphorus (P) present in some oils, can cause deactivation if oil consumption is high.
The effect of sulphur is felt most if it is released from the catalytic converter as hydrogen sulphide (H2S). This has an unpleasant odor similar to rotten eggs. Changing the fuel manufacturer may help in reducing this phenomena.
To minimize H2S emissions, it is essential that the idle CO level is within specification and that the engine emission system is functioning correctly. For additional information, refer to Section 303-08A or Section 303-08B.
ani_caut.gif CAUTION: If temperatures exceeding 900°C are achieved the catalyst substrates will start to deteriorate. It is important that the cause is defined and rectified if subsequent melts are to be prevented.
Catalyst melts are normally accompanied by loss of power due to excessive back pressure. For additional information, refer to Section 303-07A or Section 303-07B.
High substrate temperatures are caused by the ignition or the fuel systems. For additional information, refer to Section 303-07A or Section 303-07B.
Misfires at high engine speed may result in an almost instantaneous melt.

I have an S reg 1999 ford fiesta 1.25 Ztec i recently took it for an MOT and it failed because of extremely high emissions. i have changed the lambda/oxygen sensor, given it an oil change with filter, new...


this possibly will be the MAF sensor or even the throttle itself, auto choke are a bit of a pain on fords and tend to stick the best way would be to take it to a place where they have equipment to test these things on i am surprised the mot center didn't tell you what the problem could be what is causing it to do it so you can get it sorted..but anyway sounds like the MAF might be playing up...hope this helps

Ford failed MOT on High CO emission


High CO usualy means the O2 sensors are not reading properly. Take it to a parts store that can read codes, I know Auto Zone does in my area. If it is the O2 sensor it is an easy fix but the sensors run about $50.00 each.

Ford Mondeo failed its MOT exhaust emisson test


The advice that the garage gave you seems right. If any bushes were worn they would show up on the MOT Test. Try taking it to another garage to check out the Cat for your peace of mind.
