#473241 Focus Focus 2.0 2006 - Radio Antenna

Posted by mjt on 05 April 2015 - 09:50 AM

I may be wrong but I think the antenna length is set to a specific fraction of a wavelength so it is effectively tuned to a small range of frequencies. If you just crop off an arbitrary amount you destroy this tuning. If you live in a strong signal area you probably won't notice it but it's effective range could be compromised.

#470897 1600 Tdci Engine Cutting Out

Posted by mjt on 29 March 2015 - 09:43 AM

What have you used to read the codes? When our 1.8Tdci did this it turned out to be the cam sensor, but that threw up a code that was readable on the garage's diagnostic equipment.

#468647 Strange Oil Dipstick Reading

Posted by mjt on 23 March 2015 - 10:12 AM

Took it for a run and did about 15 miles then got home and turned engine off for an hour . Went back to check oil and upon pulling out the dipstick there was no oil on it! Put it in again and gave a normal reading !!!

Jon, this seems to be normal, mine does the same (1.8HE petrol). I have a theory that the o-ring on the dipstick forms an airtight seal that pressurises the dipstick tube, preventing the oil moving up it - until you remove the dipstick and release the pressure.

The information that is wrong does not affect using them. I just pointed that out to warn that sellers can make exaggerated and/or downright incorrect claims about their products and it's best to treat them with a modicum of circumspection :)

#465591 Engine Revs Hang Between Gears

Posted by mjt on 15 March 2015 - 09:00 AM

Yes, those K-series engines were very prone to HGF, especially the early ones with plastic dowels between head and block. Beyond 50K miles it was almost guaranteed. Not the best design of engine, Rover (and Land Rover) struggled to find a gasket design that would last.

#463172 Which Is The Better 1.6Tdci 2.0Tdci Engine

Posted by mjt on 09 March 2015 - 04:39 PM

I think someone had lost the plot a a bit when it came to the Mk2-2.5


I agree Darren. Compared to our old Mk1.5 I regard my Mk2.5 as a bit of a design disaster. I reckon they must have given it to some work experience kid! :rolleyes:

Andrew, I take it you mean that when you come off the gas and declutch for your gearchange the revs stay high? If so that can't be a clutch problem. Assuming it's not something as simple as a sticking throttle cable or butterfly it might be the idle control valve.

#458837 Blanked Egr, Now Eml Is On 18,000 Miles Later

E.G.R.V.'s are purely E.U. emission control , as are D.P.F.'s -  both are diesel engine killers.

Unfortunately un-emission-controlled diesel engines are also human killers. Diesels have always been dirty engines and however much stuff is bolted on they will never be really clean. Even the awful DPF doesn't completely remove particulates which are so small that, once in the lungs, they get into the bloodstream and the EGR doesn't reduce the nitrous oxides that are causing such problems in urban areas. Attempts to clean them up are simply hobbling their performance and adding to both the initial and running costs and so reducing the benefits compared to petrol. Also, of course, deleting these components simply increases these harmful emissions.


I know petrol engines are far from perfect but their emissions are less harmful to heath and a lot simpler to control. I've been driving a diesel Focus for the last five years. It's the first I've owned and I will freely admit that I find it a much nicer drive than my newer petrol Focus but I won't be buying another diesel.

I'd strip insulation gently with a stanley blade as they look very thin,
Double them back on themselves and twist the copper to fatten it up a bit prior to crimping,


Take care if stripping by this method as it's all too easy to nick the conductors and produce a weak point that can fracture due to vibration. It's worth investing in a proper tool such as this, which is not hugely expensive and then you've always got it for the future.


Also I would advise against twisting the conductors before crimping as they will then cut into one another, again producing a weak joint. By all means strip double length and fold back to fatten up if necessary to get a snug fit prior to crimping but don't twist.

If you can run to it a ratchet crimping tool such as this is preferable to the simple plier type as it gives consistent results with no danger of over- or under-crimping.

DMF = Dual Mass Flywheel. The flywheel is in two concentric parts connected by springs to damp out the impulses from the engine. This is supposedly an improvement over the older method of having the springs in the clutch driven plate but it's more expensive to fix if a problem develops.

#446677 Relocating The Washer Jets

Posted by mjt on 20 January 2015 - 09:15 PM

Because of the steeper angle you'll find it much more tricky to adjust the jets to fall in the correct place on the screen and the airflow at different speeds will have more effect in deflecting the flow. I found this a particular problem on a white van-based motor caravan. Most white vans have quite snub noses so the jets have to be positioned immediately below the screen. It's almost impossible to get the adjustment right and then it changes depending on road speed.

#440649 Knocking Noise On Full Lock

Posted by mjt on 31 December 2014 - 11:31 AM

 Can understand when CV joints failing if a perished boot isn't spotted and all the grease gets flung out but yours sounds like a faulty part in some way.


It's always possible a split boot has been replaced and some dirt got into the joint while doing that.

I find fiddling with one's knob whilst driving can be very distracting . . . . :D

#434801 Zetec 1.6 - How Does One Replace Battery?

Posted by mjt on 07 December 2014 - 10:46 AM

I personally start the car at this point saves faffing about for codes/resetting windows etc.


If you're suggesting leaving the engine running whilst removing the battery this is a very bad idea. The battery acts as a very large smoothing capacitor. Without it there will be a lot of voltage spikes on the electrical system which can damage sensitive electronics like the ECU, GEM and instrument cluster. Also if the positive battery lead accidentally touches the chassis you could instantly blow your alternator.


If you want to avoid 'faffing about with codes' the best way is to connect a small battery across the leads before disconnecting them. That will maintain your codes and in case of an accidental short the small battery won't provide enough current to do any damage. You can make up a 12V battery from 8 AA cells using a battery box like this. I think it's possible to connect this using the 12V cig lighter socket as long as this is permanently live.
