It needs to go on a proper tester as the flashing MIL means its a level-2 fault and so not classed as "Generic" ODBII fault which is why your reader can't tell you what is wrong. "Random multiple misfires" or "P0300" is normally ignition coil related so possibly the coilpack, ignition leads or...

That would be a Blog i'd subscribe to Fred... do it!

Winner!!!! Next time don't wash the engine ;)

And, in the real world it adds 5bhp and actually increases fuel consumption. I removed the setup from my 2004 K4M and it now hapily runs a 38-40mpg all day long.

The Laguna II DCi's, especially the F9Q's had a known issue with broken boost pressure sensors and associated wiring breaking at the connectors and we used to cable tie the wiring down to stop it happening. This is deffo turning in to a job that needs you to see the Live data stream to go...

Its been I while since I've played with an iPhone as I switched to Blackberrys after my 3G died but I thought iTunes and Outlook were all you needed to backup and sync contacts, music and other media types.

Another "Issue" I foresee, without being able to access the ECM Gaz, is you don't know the actual spec of the engine the ECU was driving. Okay, it was most likely an ex-Cup car so fairly standard on the internals and rev limits but without the ability to access the map on it you've no idea how a...

Oh no, its right - Its a mesh type filter that dangles from the pump pick-up but as Fred said above do not touch it as it will break. Besides, its only there to stop big stuff getting sucked up and fuel quality today is so much better than it was in the 80's.

I still think you should let me have it all Gaz ;)

It is possible for a timing belt failure to bruise a bearing causing the crank not to spin as freely as it should but its more often than not, not an issue.

Does the head actaully need replacing, if so why? Normally belt failures result in bent valves only and the seats/guides survive meaning a rebuild cost of around £75-200.

It depends on where you're from but yes, I think so! Personally, if you're paying for the head i'd say £600 tops!

Hang on, let me get this right; they want YOU to supply a working cylinder head and for an extra £1000 they will fit it along with a new timing belt? FPMSL... I need to start charging more!!!!!

I've never had to replace these after a timing belt failure on an F4R as the collision normally knocks the rockers off the seating so unless they've gotten under a cam lobe and jammed it, its unlikely (though if the cams have jammed it will have spun the pulley on tat cam so it is possible that...

Its an easy enough job and should take you 5-10 mins depending on how handy you are with the spanners, even in the dark. From the upper inlet plenum disconnect the MAP Sensor, Air Temp, Coilpack and Throttle Body multiplugs and then disconnect the plug leads from the coilpack itself. Note, the...

You can't just add the dephaser pulley to the inlet cam and expect the VVC to work i'm afraid as its not that simple.

Remove the upper inlet plenum, pull out the plug leads and check the plug wells for water.... I bet they're full

Only under full, wide open throttle or at any throttle position?

Did you not have to install a firewall Tony? Does it not need to pass scrutineering? I know what you mean though about buying this stuff as my 19's fuel lines cost around £400 to do with all the swivels and unions. Chrispy - Fuel lines in the cabin is frowned upon because in the event of an...

Don't push them thru, they should be about flush with the outer face of the head.

Yes, they should be... Even the Megane I and Laguna II variants

Don't run fuel inside the cabin area of the vehicle - If its the only thing you put on the outside/underside, make it this! Fred had the best tip IMO - Run the standard plastic "tank to engine bay" lines as it fits in the standard clips then replace the flexible sections that run to the fuel...

Silly question but are you sure you're reading it right? When the big hand points to 12... it means BAR not PSi. I'm more worried about #1 not reading anything at all... that's valve seal rather than ring seal. What prompted you to carry out a compression test in the first place?

yes, yes, yes and erm, yes! That's gonna upset the Evo and Subaru massif

8mm ID is fine yes.... aka "Dash eight"

With resistance values you want them to be as low as possible eg. as close to 0.00 Ohms as you're gonna get (But that's not going ot happen due to the wire construction itself). Normally a good stable Earth on a Clio would read around 0.01 - 0.05 Ohms. A wire brush, some copper grease and some...

That is only true of the cheap hose PSJ. If you buy a quality item, such as the Goodridge, I promise you the hose wil outlast you! Honestly, you try cutting the stuff to fit the connections and you see its not your typical butile rubber covered in a cheap stainless wire braid...

The Laguna II DCi's suffer with a similar problem which is normally to do with the boost pressure switch... hard to say without seeing the live data though. Could even be a boost leak or and actuator problem

Earth problem is the most likely cause. It could also be a genuine sensor or even a coolant system problem but start simple before getting really involved. Check the main ECM/Loom earth that is bolted to the front of the block just below the main coolant pipe to the rear of the waterpump...
