Blue Smoke and Smell of Oil and Petrol

[JamesT5]

When you turn the ingition on, can you hear the fuel pump?

Mine sounds like that when the fuel pump died, or I've forgotten to turn it on!

I'm open to options.

This couldn't have been caused by that oil you were running on for a short period earlier this year? Fingers crossed it's something not too costly.

You sure all the boost hoses are ok, no major leaks, as this will make it ruff as hell at idle and beyond, scared the hell out of me when I unknowingly popped a lower boost hose on the V790R, trying to reverse up a bank by the house,it idled as rough as a badgers a#se and terrible to rev, smoked a bit too. I was lucky as all I had to fix was a broken jubilee clip

Watched the clip and i fail to see why it wont start if the turbo is goosed. Needs a compression test. Are you getting spark. Are the injectors opening. Is there fuel in the car. Has the car lost any power sudenly or gradually. Get the compression checked. Hopfully you wont of killed the bored with poor decisions in the past.

That is my feeling too, my mate has a focus in his garage at the moment, it has got a failing turbo, it run, but makes one hell on a racket!

The AA says it has spark, should like fuel to me, my fuel pump on mine just went, drove it home fine, came to it the next day, would not start!

On the 850's (No idea about the P2s) you can easily get the pump out, we tapped it, and it started working, was fine for 2 days, then did it again, changed the pump, been fine even since.

I've had boost hoses pop off before and this seems different somehow, I will double check though Adrian, thanks.

I doubt it very much.

Never seen smoke from the exhaust from a fueling problem before but your theory would be logical on the non-starting side of the issue.

I've got a compression test kit but the second AA patrol are coming out this morning to do the 'second opinion' and to organise me a hire car and recovery. I'm planning on getting taken to BVS again as they did such a good job on the rectification of my clutch and gearbox problem.

Is this the same this it did when you were at mine James?

If so, it's not the turbo as it ran fine when it finally started. I'd be looking at the ignition system (remember the trouble you had with the coil pack wiring) or the ETM.

Yes that's the time Martin, yes.

Interestingly, coming back to Paul's theory about the fuel pump, the patrol man tried to release fuel pressure from the fuel rail and nothing came out so as a precaution we went out and got some petrol (about a gallon) and plonked some in the tank and it still wouldn't start.

I'm going out to do some inspections of my own this morning before the AA arrive to see if will help narrow down the issue.

One of my senior bosses at work really wasn't happy that I've had to take the day off work today and really couldn't work out why a trip of 32 miles from my place in the Brecon Beacons to my place of work near Cwmbran wasn't possible on public transport at 5am on a Sunday morning. Anyway, sorry just a little rant on the end there.

No fuel pressure even after petrol tat sounds like the fuel pump then hopefully thats it as its a fairly cheap fix

[M-R-P]

Fuel pump... Hmmmmm

[JamesT5]

I went with Paul's theory with the fuel pump. I banged the fuel pump and got my other half to sit in the drivers seat and asked her to start the engine. It spluttered and started and then I got this.......

I managed to get the induction filter to 'gasp' so I think we can rule out the turbo and there's no nasty knocking sounds from the engine bay, the mystery deepens....

I wonder if Shell put the wrong fuel in their pumps! I always make sure I pick up the Shell V-Power Nitro+ and my receipts and Shell Reward card will verify that. I wonder if there is actually diesel in the tank somewhere, just a theory!

[JUDGENINJA]

Turbo best case..... Engine screwed at worst..

[M-R-P]

Isn't that just unburnt fuel smoking off from the cat? If the cat was saturated with petrol, wouldn't it smoke like that?
What's it smell like?

[Sharkey R]

When I used to work in a local supermarkets fuel station we had a customer come in to fill up in a 740. She unwittingly filled it up with diesel and then started the engine, within 30 seconds the whole garage was full of smoke. I'd be very surprised if that's what's happened due to the fact that the smoke that she kicked out that day was very thick and a hell of a lot of it.

[JamesT5]

The AA Patrolman took a sample of the fuel out of the fuel rail and matched it to the stuff in his jerry can and it looked and smelt identical. Mis-fueling scenario highly unlikely. But as we took it out to the Petrol station just to rule out a fuel based issue, the car got about 20 yards down the drive and there was more smoke, this time with a strong smell of burning oil!

He's convinced a seal has gone in the Turbo so I've had it carted off to the Volvo Specialist again and I'll phone them tomorrow to arrange for the inspection and repair. I should be covered on my garage repair cover but either way a big bill is coming my way, the AA will only pay out on a recon or new turbo so a secondhand one is not an option at the moment. He did comment on how clean my oil was and the engine (I quote) "sounded nice and sweet".

At least if it is the turbo and I have to have recon fitted, I should get my boost issues sorted. I wonder if that's been my 'power' issue for quite a while! I'll keep you all updated when I know more but I'm due back in work tomorrow so I'll update when I can.

I hate to say it James, but in your second video the engine was clearly misfiring....you could hear it in the exhaust note! That was not running smooth.
White smoke generally indicates water/coolant being burned in combustion chamber. It's not very clear in your video but it also looks blue in places....this would indicate burning oil.
So, based on those only two conclusions, either your Turbo is bust or your headgasket is leaking.
If your coolant level has not altered and your not getting any rapid build up of pressure in the expansion bottle, then my moneys on it being your Turbo.
The reason why your car wouldn't start in your first video, may have been because of a lack of compression or spark plugs wet with fuel, borewashing the cylinders and therefore preventing the car from starting.
If you tapped the fuel pump and the car then started, then your are super unlucky, because a worn faulty fuel pump won't cause excessive white/blue smoke - therefore, you could be looking at a replacement pump also, as well as a possible Turbo failure. 2 faults in one day!!! that sucks!
I gotta ask you, what's the mileage on your car?
If you have to replace both then is it seriously worth spending all that money?
Fuel pump will be at a guess £200 and I advise you don't buy second hand one. Golden rule is never buy anything electrical, second hand. New turbo is £600 + fitting. Your looking at a bill of near to or just over £1000 and that's assuming the AA pay out!
You have to get authorisation first, they could also send out a loss adjuster who will want to see proof of servicing.
Don't just assume that the AA are going to cover the cost of this one, after all, you only made a recent claim not long ago and will only cover you up to £465.
