Default Car mechanics forum - help!

My two year old V6 turbo-diesel did a big backfire, lost power but then ran intermittently unevenly to get me home (about 2 miles)

I had topped up with fuel a few days earlier and done about thirty miles since refuelling - I'm pretty sure I put diesel in!

On return home the engine was beginning to pick up power again but when I gave a wee rev whilst stationary black smoke shot out the exhaust.

Thinking of limping in to the garage for service on Monday it's first service (18,000 miles) and the garage is about ten miles away. Can call the AA recovery if things seem much worse once I've got away from home.

There are no system warning lights showing fault.

Should I get steam if a gasket has blown? Any diagnosis advice or suggestions would be appreciated.

Hopefully things are not as bad as I think they might be !

Hmmm. Diesels don't usually backfire, it might possibly be a/some teeth stripped from a timing belt (if you have a belt rather than a chain cam ! ) or possibly a piston ring or valve breaking down.
In my experience a blown head gasket doesn't usually make a noise but you tend to get water vapour in the exhaust after it's warmed up and probably evidence of oil in the coolant (filler tank or radiator ).
Either way I'd recommend you getting it to a dealership for proper diagnosis and repair...it does sound a little ominous. It would be best not to drive it any further until someone can identify the cause. Good luck !

Thanks RangeRover and Centaur

@ RangeRover - No steam but just black oil or diesel from exhaust on gentle test rev.

Garage rung this morning to advise they had a cancellation and could check car and do service.

Drove the ten miles to the Skoda dealer belching out black smoke like a lorry every time I used the accelerator. Kept an eagle eye on the temperature guages and watched out for warning lights.

Verdict:- The intercooler had become loose and disrupted the entire engine management system.

Try to be an optimist when apparant disaster strikes

Promise not to complain about the probably outrageous cost of the first service

Cool Re: Car mechanics forum - help!

A first service is not normally that expensive - I think mine and swmbo's was only(!) just over 100 (mine is a 2ltr and swmbo's is a 1.4ltr, both turbo diesels). It's subsequent services that get more expensive, mine recently had it's second and was just under 250! (which included a drain and refill of the braking system).

Your 'failure' parts/labour etc will be covered under warranty.

I don't know but I know a man who does!

Well here's the information about the 01 Plate

The Number 1 Plate

Why not buy the plate and transfer it to a diesel transit of your choice?

In the very unlikely situation that it is petrol then the injectors must have been switched on all the time the engine wasn't !

P.S. You don't need to SHOUT !

Default 99 Ford Focus Diesel engine revs down on accelerating

Sorry for the thread creep, but seeing as there are people on here who seem to know a thing or two about Diesel engines, I was wondering if you could help me with the following. If you have suggestions for another forum on which to post this then please send that too:

1999 British-registered Ford Focus Diesel
124000 miles

I've just purchased this car used from colleague whom I trust. Lately though, as I'm driving, accelerating in second, third or fourth gear, the engine just revvs back down to idle for now apparent reason. At the same time, the glow plug light indicator (the one with the filament coil) flashes. No other lights come on (not even the engine management light). No strange noises are heard. The only cure to this is to simply swith the engine off and back on again. Sometimes the problem happens every 3 minutes, but I've also gone 80 miles without anything happening all day.

I've taken the car to a mechanic. They've done a diagnostic scan but have found nothing. They admit there's a problem as they drove the car and experienced the fault themselves. They now recommend that I take the car to a Ford dealer here in England. I'll do that but it's quite expensive so I was wondering whether someone might have an idea of what the problem is.

Thanks.

hope you get it sorted anyway

Hi

Could you please help me with a problem I have with my M Reg VW Golf 1400.

The problem when it starts it is very sluggish. It ticks over ok when I get it started but as soon as I put my foot on the accelerator the revs go right down and it stops and will not start again and will only fire up if I keep the key turning. I called the AA out and was told it may be the head gasket, if this is the case, can you tell me if it is hard to change, or how much would a garage charge to do the job.

Regards

Angry Re: Car mechanics forum - help!

I just did parked my 2000 Volkswagen Jetta diesel and in five minutes attempted start engine again - not even little click sound came out. Battery is fine. What other problem than faulty battery there can be ? Maybe starter gone? Is there other electrical relay involved in starting procedure?
Please give me hint what to do - thanks. Karel

if that dont work try this
if you can find the starter motor it has wires on it see if they are connected to it because they can come loose then if thats ok give the starter a little wack with hammer it might just be sticking.
ok cool.

Default Re: Car mechanics forum - help!

Were ALL the cylinders full of fuel or only one or two ?

Are you losing any coolant...does the reservoir need topping up ?
Are you losing any brake fluid ?

I still feel that it's extremely unlikely to have been 'neat' fuel...it could well be a mixture of fuel/coolant which would smell and feel like fuel. In order to fill a cylinder sufficiently to 'hydraulic' it, means the injectors have to be working when the engine is shut off, which indicates a severe electrical malfunction and/or possibly a fault in the computer 'brain' system.

Will the engine run if you replace the sparkplugs ?

If it does, and whilst it's still running, remove the fuse which supplies the fuel pump....it should be marked on the fusebox lid.....and the engine should stop. Leave the fuse out for about an hour and then remove the sparkplugs again and turn the engine over on the starter....does any liquid come out of any of the cylinders ?

Assuming the vehicle has a catalyser fitted it will be severely damaged if the engine is run with excess unburnt fuel going into the exhaust system....any quantity of black smoke indicates overfuelling.

P.S. The 'oldies' on here can read ordinary sized print.....and mostly try to help where they can

It definately smelt and felt like fuel i had a look under the tank briefly and it looks as if its a new fuel pump now you mentioned it the water was low but this is no indicator as the thing was recently bought from a farmer who had it stood for three months as he couldnt get in to the bonett to find out the problem (the pull cable had started to cease and pulled off the handle) i havent had chance to to try to strart it yet hopefully nothings bent as soon as i do ill leave the plugs out and see what sprays out ill try that trick with the fuel pump this is definately an odd ball this one i take it the injectors are electronically controlled ie openind just before ignition could the ecu be telling them to stay open as it is a common rail system?? the big hammer in the garage is looking favourable appologies to all the old geezers was just messin you have ya uses who else would tell us how hard you lot had it in the old days.lol (JOKE!!)

If the pots were full of fuel then you have a serious electrical malfunction as previously stated. Since the injectors are opened/closed by the ECU, then I would first locate the ECU and check if it was damp/waterlogged or obviously damaged. If you can't identify an obvious fault and unless you're any good at electronics, it looks like you need professional help.

It might be something as simple as the glowplug relay which is shorting out and taking power from the on/off solenoid in the diesel fuel pump...or it may just be the solenoid in the pump. You could try replacing each one in turn, starting with the on/off solenoid.

Does the car start from cold ok, and does the glowplug light come on and go off without flickering ?

Does the engine ever 'run on' after you switch it off ?

Thanks Centaur,

In answer to your questions:

1. the car starts from cold like a dream. This morning it was about 2 degrees C and it started straight away. No flickering of the glow plug light at all.

2. no the engine does not run on after I switch it off

I went to the local mechanic to pick it up this morning, they'd found nothing by running a scan on it (although they admitted there was a problem as they witnessed it first hand when they took it for a spin).

Could it be a contaminant of some sort in the fuel system? I've been running on less than a quarter tank these days. I've just filled it up to the max to dilute anything just in case.

How much does it cost (parts + time spent) to replace the on/off solenoid or the solenoid in the pump? Can someone with barely above average DIY skills like me do it by just getting the parts on-line?

Thanks for your on-going help.
