Firstly I'm not overly mechanically minded, so go easy on the replies.
I've recently heard a whining sound when the engine is warmed up. If I rev the car, it "speeds up" with the engine. The fan is coming on, so I don't think it's that. The annoying thing is, it's an intermittent event, so naturally when I took it to a garage, it didn't "perform"
it waited until I got home, then started. This will happen when the car is stationary.
Is there a motor that drives the fan that could be on it's way out? Or could it be something more sinister.
Any feedback greatly appreciated Read more
Feature on BBC South last night about a bloke that's developed some sort of valve that's claimed to reduce engine emissions:
news.bbc.co.uk/1/hi/england/7953443.stm
I'm at work and haven't got headphones so I can't listen to it again now, but IIRC they measured the CO2 from a bike and it dropped from ~4% to <1%. I think the valve opens as the piston goes down, reducing the 'friction' (resistance?), allegedly.
Might be more snake oil, but it sounded interesting, and the program said they were going to test it out on at least one of their cars over the next week or two - I'll try to remember to find out how they get on.
Can't find anything on t'internet about this.

the bike was running rich so by adding the valve this allowed air into the manifold making it run weaker. The principle of the valve is that on the overun with the butterflies shut on the carbs vacum would be reduced by allowing air through the spring loaded valve reducing the amount of air dragged through the carbs pulling fuel with it.
On the modern injection engine fuel shuts off on the overun altogether reducing emissions even further!
Woodspeed was right, the same thing as ecotec years & years ago. If the vehicle was tuned right to start with they made no difference to emissions or economey. I tried quite a few on a fleet of vehicles for 5 years.
Hi all,
recently bought a Mondeo TDCi. In the event of anything fuelling-related going wrong, I dont want to put myself into the hands of a Ford dealership (various reasons.)
Can anyone recommend a diesel specialist in Scotland, preferably West Coast, Glasgow, Lanarkshire region?

This GDI engine will not tick over. It starts easily and drives OK, except the engine will not idle at constant revs. When you start the engine (warm or cold), the revs rise to about 1500, then momenterily fall to around 750, then falls to zero in about 4 seconds. This deterioration took place overnight after a mild front-end crunch which wiped out the bumper, dented the front of the bonnet, but was not so bad as to damage any of the lights. Perhaps the crunch jolted something loose or damaged a sensor, but nothing appears to be out of place on a visual check. Any suggestions please ?
Thanks

Having just bought a new CRV. I am currently contemplating about the 5yr fixed price service. However looking at the Honda Brochure. At the back of the brochure it mentions the many different Honda happiness packages including roadside assistance. Yes the car comes with 3 yrs roadside recovery (AA). The write up in the brochure for roadside assistance quite clearly states. Qualifying customers who have their Honda serviced at one of our participating dealerships will now recieve complimentry roadside assistance. My question is so i take out the 5yr Fixed price serving £830 for the CRV, does that mean years 4 & 5 i get free roadside recovery. When i rung Honda last week they didnt know and said they would ring back (they didnt). Today i rang and i have to say its not as clear as what it states in the brochure. Why is it not so clear, because you have to find out who the participating dealers are. Who qualifies and another question i will be asking in writing is what if i was not to subscribe to a fixed price service deal and subscribed to the dealers service deal or paid as and when the vehicle was serviced would i still qualify for free roadside assistance. Anybody any experience of what i am posting here.

Ideas needed please. I have a damaged 320d engine to repair for a pal. It has suffered a mashed piston and head indentations due to the ingestion of a metal intake manifold vane. The piston protrusion has been measured so that the correct head gasket can be provided and the head will be skimmed. This leaves me with a problem. Although the head is flat, the valves are slightly pocketed and will therefore become closer to the piston when the head is machined. I usually put a piece of plasticine in the combustion area to confirm clearances during a dry build. My problem here is that the tappets are hydraulic and therefore I can't duplicate the true positions as in when the engine is in service. I have considered charging the tappets with air but air is compressible and the follower will not properly follow the cam. I have considered replacing a tappet with an adjustable rod to set the geometry but I don't think I will be able to take the gap up correctly when in position. Any thoughts please? Regards. Read more
Thank you for your advice but I will not be grinding the valve stems as they are often hardened to prevent wear and this would not result in the tappets being lifted to cause the rockers to follow the cam correctly. Thank you anyway. Regards.
The Motor Vehicle (Test) (Amendement) Regulations 2009 in force on 6th April, 2009
will increase the fees for annual testing of motor vehicles. Increases are between 1.64 to 1.88%
So if you want to save a bob or two book one early.

So would I. I was under the impression that MOT testing stations paid a percentage of the test to the DVLA - a government department at the end of the day.
I have the chance to buy a 1972 Bentley Corniche at a good price, but it needs engine work. I want to put a good modern engine in it, but am a complete novice. Any suggestions for appropriate engine make and size? Am looking to end up with a good solid car, rather than a racer. I want to keep the car rather than sell it on. Thanks for any suggestions.

Wow, April 1 already. Where does the time go? ;-)
Engine stalls at speed on the motorway - every few months. Very scary!
Usually happens near an airport and the Jag repairer we use says it may be due to electronic interference - but yesterday it happened twice, going north on the A1(M) near exit 7 and on the way home going South on the A1 near South Mimms.
Anyone else had this problem? and any ideas as to the cause ? Read more
So the ECU is still running as it has detected the speed sensor but no crank sensor thus a stall message. This starting to sound like a ignition/fuel pump relay problem. Regards Peter

Cheers, will try that one. May cut down on labour time and costs if I can point them in a more certain direction.
