  1. Hi, I have a Mk 3 Cortina fitted with a 3.1 Essex V6. After sorting out lots of problems with the ignition, wiring, fuel pump, etc etc I am having problems with getting the engine to idle. I have overhauled the Weber 38 DGAS carb but Im not sure about one thing, It concerns the calibrated air holes that allow air to enter and mix with fuel to go to the mixture screws. On my carb both of these appear to be blocked ( with what Im not sure ).A friend suggested people often block these as they are not needed but my logic say why are they there if not required. I have the Haynes Weber manual but no mention is given to checking these items. Do anyone know if these could be causing my idling problem and if so how do you unblock them. ( I have tried to prod a pin into them with no luck. Can they be drilled out and if so what size is the hole? Any help with this problem would be most welcome. Thanks, John

  3. Hi, I need to check and maybe adjust the valve clearances on my Essex V6 engine, the firing order for this engine is 1 4 2 5 3 6. To my way of thinking the best way to check these is to get number 1 cylinder to TDC on compression stroke when both valves should be closed, then check clearances on these valves, then turn engine 120 degrees when number 4 cylinder is TDC and repeat and so on. This way however is apparently not the way to do it. From what I have read various inlet and exhaust valves should be rocking and other valves are adjusted. My way seems much simpler. Can someone explain where my logic is wrong and what is the best way to do it ? Thanks, John.
  4. Hi It sounds like it might be a worn driveshaft joint or maybe a worn top suspension mount. John
  5. Hi, I recently bought a MK3 Cortina (1973) which has been fitted with a 3.1 L essex V6. Although the tachometer works it is showing the wrong revs ( ie about 300 revs at idle ) I think this is because the tachometer was originally for a 4 cylinder engine. Do anyone know if this can be sorted by a switch setting on the back of the Tach or if not what I can do to fix it. ( I havent got round to removing the instrument panel yet ). Cheers, John
  6. Hi, thanks for the replies,I have since found out the firing order and cylinder numbers are stamped on the inlet manifold, so hopefully tomorrow I will have a go at the timing and reset the carb basic settings. fingers crossed. now going to try and download some pictures.

  8. Hi, I have just bought a MK 3 cortina fitted with the Essex V6 bored out to 3.1 lts. The bodywork is excellent but the engine runs like a bag of nails. The plugs, cap, rotor arm and leads have been renewed. Before I strip down the twin choke Weber I want to check the timing is spot on and here lies the problem. When trying to use the strobe light, which is about 20 years old now, i cannot see any notch on the pulley next to the W mark although the strobe is pulsing light. Maybe the timing is way off or the firing order is wrong. Im sure the correct order is 1 4 2 5 3 6 but im not sure of how each cylinder is numbered. I think it should be FRONT 1 2 3 4 5 6 but checking online some diagrams show the order as FRONT 1 2 3 6 5 4 Also the car has electronic ignition and not points so I dont think I can check the timing static. Can anyone give me any ideas on this. Thanks in advance, John.
  9. Hi, Thanks for the reply, I may try to align the carousel but Im not sure of the procedure you mention.
  10. Hi, I have a 1999 1.2 Fiesta fitted with the 6 disc ford radio unit. Recently the 4th disc refused to play, all that could be heard was a whirring sound. It was not possible to eject any discs. I then removed the unit and took off the cover. After removing a few screws I was able to remove the plastic disc holders and extract all the CD s. I then reassembled the unit and tried to play the discs. Now , only disc 1 would play. I then repeated above to remove the discs. The car is not worth a new CD player. Do anyone know the proper procedure to check, and reassemble the disc holders or have any ideas what could be wrong. Thanks, John
  11. Hi, there is a tool you can buy, only 2 or 3 pounds, I think from Wilco or similar, its a small cube with pins on each face that fits into the slots in the brake piston, this attaches to a normal socket wrench and makes winding back the piston quick and easy. Because the pins on each face are spaced slightly differently this tool can be used on different types of car. It worked a treat on my mondeo without the need of removing the caliper. John
  12. Hi, Im having a problem with the handbrake on my 52 plate Mondeo saloon that is gradually getting worse. When the lever is pulled there is a lot of tension felt but no clicks of the ratchet until at the top position when it will click once. however this will not be enough to hold the car and im having to leave the car in gear. The rear callipurs were replaced along with I seized cable about a year ago by my friendly mechanic. At the moment because of the bad weather I havn`t had a chance to get underneath to have a look. I suspect it is either a seized cable or a faulty lever/auto adjustment unit. my questions are, if its a seized cable and I replace it, does the whole set up have to be adjusted in some way or, if its the lever mechanism ( I believe there was a recall on these ) can anything be done to lubricate or adjust these. Any advice would be great, thanks, John
  13. Hi, my rear bearing went recently on my 52 plate mondeo saloon, dont know if the bearing differs on estates, but I found a site on ebay that only cost about £29 for a new bearing and about £4 postage. John
  14. Just an update, tried a new coil pack and all is well. thanks for the input Peter, John
  15. Hi, I have a 02 1.8 petrol mondeo that has started to misfire slightly under load, such as at 25 mph in 4th gear. The spark plugs were changed about 6 months ago. The car idles and accelerates fine. Im inclined to think the coil is at fault but a friend thinks it could be the plug leads. There are no fault codes. Is there any test I can do to pinpoint the problem rather than just replacing parts at random thanks, John
