Forums Forums Enthusiast Forums A - Z Autowirral Smoke billowing from exhaust

today iwentto the Derv Doctor in Ashbourne to geta dump valve fitted. all went well and the fella commented on how wellthe engine had been looked after, but said when idle the engine judders and looks as if thers air traped inside the pistons(i think). hetold me it would be okay to drive home and shouldnt give me any problems for a couple of weeks but advised me to take it to a garage sooner rather than later. by the time i got my car bak the garage i go to for everythink else had closed so i just said i'd phone in the mornin.
everythin went ok driving home, went to my girlfriends till about 10:00 then piked my mate up from neston rec. turned the engine off whilst i waited for him, turned the engine on and a huge cloud of black smoke was coming from the exhaustand continuing to pour out as i drove home.

what has happend? can anyone help me????

turbo's had it

barstard!!!
so how much am i lookin at 4 a different turbo? would i have 2 re-set the psi again and get another dumo valve even tho ive just paid £300 4 1 2day?

fooked if i know mate, prob best off takin it to a turbo specialist, pm stuy mac, he will point you in the right direction, thats providing its the turbo, has any one else said that to you yet. but with your psi being so high it might even be your oil valve seals ?, who knows, it could be a number of things, id deffo get it down to some one who knows what they are talkin about, cause i aint got a clue

thanks mate. i'm guna take it 2 olympic autos 2moro and c what he says. do u rekon it could be anythin 2 do with the dump valve being fitted putting pressure on the turbo or am i just panicking too much?
i'll fone up derv doctor aswel, but i wont b able 2 do the 75 mile trip if they wanna look at it.

hmmm, is it poss for you to stick your old dump valve back on

my old dump valve?

its neva had 1 just always had the standard turbo.

this happend to my old mondeo tddi and it was my turbo that was goosed mate i blew one of the pipes connectin to it and didn bother changin the pipe and in the end the turbo just gave up and had to change it all lol cant remeber how much but it wasn that expensive tho

Check your intercooler hoses mate. It sounds like a blowen intercooler hose, if of course its not the turbo. I hope its not.

The DD are pretty good, especially with DTurbos, so im sure his fitting of the dump has nothing to do with it. If it turns out it was the turbo, it was probably well on its way already.

jus phone the Derv Doctor and the lad who worked on my car said it looked as if it was only running on 3 1/2 cylinders and maybe there could b somethin wrong with the oil filter.
he said that they do new cylinders off the wall 4 £145 but i cant get to them and they cnt send them thru the post :s. so i have booked in to olympic autos but not until next friday.

3 1/2 cylinders, and they can replance a cylinder for £145

I think they mean you can change the piston, but its a full strip down job on the motor

If the car has a lumpy idle, it may be a holed piston (if you have had the boost upped) - which may be cheaper to get the motor replaced as a whole.

..on the other hand it may be a boost leak..

Its very hard to diagnose with someones discriptions, and not actually seeing the car..

took the 306 2 olympic autos this morning and have just had a phone call fom him saying that the head gasket had blown.

told him 2 fix it 4 me at a cost of no more than £500.

he said the head will ned 2 be sent off 2 be skimmed and a few other parts replaced - cambelt oil and filter etc..

do u think this is a good price?


also dont know how the derve doctor said it could have been the cylinders considering that theyre specialists!!!

head gasket replacment would mostly be labour costs as there is little parts to purchase.

So depends upon how long it would take them and how difficult it would be to take the head off.

Personally, I wouldn't pay anyone to do it, far cheaper to do it yourself if you know what you're doing. I've done mine myself.

I have no idea how much it would cost, but to me that price is quite high. I'd say £300 max, but I have no idea of labour costs?

Have you tried getting quotes anywhere else?

i aint got a quote from anywhere else no, its the only garage that i reli go 2as my uncle used 2 work ther and the fella dont rip me off! he said the head has 2 be sent off 2 be skimmed coz he dont do it, and should b ready by next saturday at the earliest, but i dunno what labour costs he charges but its always cash in hand 2 him anyway.

The HG set for the 1.9TD motor, inc the head studs etc is around £200 IIRC (What I was quoted by a motor factors for a Xantia TD engine)

Head skim - £50, plus filters and belts etc, I think £500 all in is a pretty reasonable price
