  1. Clutch Fault Identification. Hi guys, My 2004 Focus 1.8 petrol has lost all resistance in the clutch pedal. I fitted a new three part Borg and Beck clutch kit four months ago and the clutch has been fine until now , therefore , although not impossible , I am reluctant to suspect the slave cylinder (due to its recent replacement) , leaving the master cylinder as the only other culprit ! My question is :- Is there a way of finding out for sure whether the master or slave is at fault ? Thanks in anticipation.
  2. Clutch Fault Diagnosis Hi guys, My 2004 Focus 1.8 petrol has lost all resistance in the clutch pedal rendering it totally ineffective. I fitted a new three part Borg and Beck clutch kit four months ago and the clutch has been fine until now , therefore , although not impossible , I am reluctant to suspect the slave cylinder ( due to its relatively recent renewal) , leaving the master cylinder as the only other possible culprit ! My question is :- Is there a way of finding out for sure whether the master or slave is at fault ? Thanks in anticipation.

    Oil leak

    Hi guys, Upon removing the gearbox on my 2004 Ford Focus Petrol 1.8 in order to replace the clutch , I noticed a quantity of oil drip out of the bottom engine / gearbox joint. Upon inspection , there was no trace of oil on the clutch , flywheel or the crankshaft seal , yet the side of the engine was wet with oil , not only on the area enclosed by the gearbox , but also right up the whole side of the engine , meaning I have an oil leak somewhere above the gearbox which is running down onto the engine / gearbox joint . My question is , could this external oil leak have found its way past the joint and into the clutch housing ? Secondly , Haynes state that part of the seal renewal proceeded involves removing the sump. I don't doubt that it's necessary , but I was wondering why ? Many thanks.
  5. Reply to Thread Tags: None Mark 1 said:25-01-18 08:51 Compression query Further to an issue I had with my 2004 Ford Focus 1.8 a while ago , to carry out a compression test , which I duly did. Compression ranged from 70 lb/ sq. in. to 100 lb/in. sq. Given that my car suddenly lost power without any warning whatsoever , and the fact that I've already replaced plugs , leads and coil , what are the chances that the valve timing has 'slipped' due to the cambelt ? I fitted a new belt and tensioner about 7 or 8 years ago , but haven't yet done enough miles to replace it again . I understand that cambelts rarely jump in sprockets but it can occasionally happen . If the belt has indeed slipped , it would fully explain the instant power loss. Many thanks.

    DRC P0351

    Hi guys I have a 2004 Mk1 Focus 1.8 petrol. After a great deal of trouble , DTC code P0351 came up but replacing the coil , plugs and checking the connection to the coil and the HT leads has made no difference. The car still idles terribly with no power and seems like it's only firing on three cylinders whereas I'm sure it's actually firing on all 4 in reality. My question is , if everything tested fine and new plugs and coil were fitted , what else could cause this particular fault code to display ? Thanks in anticipation
  7. Hi guys. I'm new to this site so I hope I don't break any forum 'taboos' ! I have a problem with my 2004 Focus 1.8 petrol. My car suddenly started to lose power and when I stopped , it ran really 'lumpy' The breakdown guy towed me home and then performed a diagnostic test which gave the error code P0351 and said it indicated a faulty coil. It turns out that I have no spark on cylinder number one so I checked the resistances in the coil and the HT leads which all seemed to be satisfactory (according to my Haynes manual) leading me to suspect a faulty plug. When I removed the plugs , number one had an excessively large gap so I thought I'd found the problem but the problem was still there ! Still being reluctant to blame the coil , I did some online research and discovered that the coil in my wife's 2004 Fiesta shared the same specifications as the coil in my Focus , so I temporarily swapped them over together with the HT leads. This made no difference at all ! My wife's Fiesta ran perfectly well with my coil and HT leads and my car still failed to run properly using her Fiesta's components so I'm now assuming that if my coil and HT leads work perfectly well in my wife's car , they must be perfectly good ! I understand that these coils work on the 'wasted spark' principle and that one coil operates plugs 1 and 4 and the other coil operates plugs 2 and 4. Surely this means that if plug 4 is firing , then the fault can't possibly be the coil , the wiring between the coil and ECU , or the coil 'switching' mechanism in the ECU itself (coil drivers) , otherwise NO plugs would fire OR only 2 and 3 would fire ! I'm totally baffled by this ! Any advice would be so very gratefully appreciated ! Many thanks ! 🙂
