smokey jo. please help!

[jamie_clioGTT]

Hi all. Just brought a second hand t25, put it on today and she smokes like del boys 3 wheeler. Its white smoke, my plugs are black which surely points to overfuel? I don't understand why, it was fine before and all I've changed is turbo and obviously now running my pipes diffrently (cup mod)? Could really do with your help as she's my reliable daily and I have a 12 mile ride to work tommorow haha thanks chaps.

[BluntyR5GTT]

hi mate i know this wasnt on a 5 but id imagine the same applies

White smoke is normally Coolant

1) Are u losing coolant...? like is ur rad full or over flow still have any coolant.
2) you should do a do a compression test and leak down test, scope the motor.
3) Check your turbo for shaft play

[jamie_clioGTT]

Hi pal. No play in turbo, it seems sound? Tiny amount of milk at turbo return pipe but this was due to condensation as I sweated it onto the turbo, I mean very minimal. Car was spot on today until I changed turb.. Could the small amount of milk be the problem? I have no wideband as couldn't afford it this month due to buying the turbo, so have no clue of afrs.

Thanks for your help, really appreciated

[djinuk]

i presume the turbos water cooled, is it possible its worn/cracked and leaking coolant into the eghaust.. that would point to exactly what you just described..

[djinuk]

also jamie do you have a lamba bung in your downpipe, if so and you can be arsed to pop mine we could whip out with the lm1 setup and see what its doing.. however i think it probably points to the above. Does it still boost fine etc ?

Failing that you could bypass the water jacket and run it and see if you still get the white smoke.

[youngscottie]

as said white smoke is normally coolant
bridge over the coolant pipes to the turbo and see if that cures it

why did you change the turbo in the first place?

[jamie_clioGTT]

yer water cooled pal, not loosing any coolant though?

also my vaccum is rather high up, sitting at about 20 instead of normally 30..

[jamie_clioGTT]

changed turbo due to mine not pulling very well ( found out earlier its cracked), what would bridging the pipes do? (sorry bit of a novice) and no dj, no lambda bung in it :disagree:

thanks alot for the replies i really do appreciate it.

[Markey Mark (BD)]

Sounds like duff turbo to me if all you done is fitted new turbo and now you have smoke coming from exhaust. Grey smoke normally indicates dead turbo.

I'd take the elbow off and check insode the rear housing for oil residue in there.

if you bridge over the coolant pipes theres no more coolant entering the turbo
thus you can eliminate the turbo coolant being the prob if it still smokes

or refit the old turbo if smoke stops when up to temp your new blowers shagged

[jamie_clioGTT]

sorry just thought about the water and answered my own question :ashamed:

its deffinetly white smoke, could it have anything to do with the fact that i sweated the oil return pipe on and created a little bit of milk?

doubt it as the smoke would have cleared by now
have you had the car up to temp?

[jamie_clioGTT]

yes i have.. started and stopped a few times. when its warm, i start it up and its fine. 30 or 40 seconds later you cant see the end of your nose for smoke.

thank you for your time on this.

[R5TURBORON]

My old turbo on the clio turbo i had started to smoke white but only on idle was fine under boost. Is yours like this?

[jamie_clioGTT]

it does clear a little but still smokes?

[R5TURBORON]

Its got to be turbo related as it was fine before you changed it

[BluntyR5GTT]

looking at your description id agree with mark and say its the turbo

[jamie_clioGTT]

i will try bridging the coolant pipes, and go from there i think?

thanks alot chaps.

[djinuk]

if its 100% white then id be pretty certain its the water jacket on the turbo mate.. bridge them pipes and take it for a blast.. then if it stops.. go ram the turbo up whoevas ass you bought it off.

Best getting a turbo off here really dude.. theres less chance of it being a duffer.

[jamie_clioGTT]

it was off here, im not blaming turbo just yet, and certainly not blaming who i brought it off as he seems very genuine. i should mention that my car did excactly this when i first built it and seemed to fix itself...

[BriC]

go ram the turbo up whoevas ass you bought it off.

:laugh:

Cheers DJ!

Yeh, do some checks mate, and if it turns out to be the turbo at fault, my original offer still stands :)

[djinuk]

hahah , oops bric.. !.. :cool:

Bric did this turbo could of a good motor ? - the fact it came of bric now changes the fact that id doubt it to be the turbo, unless it wasnt used before..

hmm hmm

[BriC]

Well, as I explained to Jamie, I bought the turbo for my GTT off a member from here quite a while back (seller isn't a member of the club anymore) but never got around to fitting it. It was sold to me as good working order and refurbed a couple of hundred miles ago. Think I bought it for about £250 plus postage. Sold it to Jamie for less than I bought it for but on the basis that he had a 7 day money back guarantee off me, should he find the turbo is knackered on fitting.

[James5]

I am with Mark on saying turbo knackered, a turbo can smoke white even without coolant going through the turbo, I have had a few turbo's do this.

[djinuk]

i imagine it can smoke (i.e blue smoke) but surely chucking out white smoke has to be coolant ?? ( i may be wrong)

Cant ask fairer than a 7 day money back guarantee i guess, thank god for rtoc and the *good* members.

[Brigsy]

If its started smoking after fitting another turbo it can only be a duff turbo...the white smoke will be oil, when mine went boom a couple of weeks ago the smoke was pure white...

[jamie_clioGTT]

Bric has been an apsolute ledgend about this to be honest. Just going to try a few things then before I blame turbo as my car did this (excactly this) when I first built it.

I will post any further findings up later on.

Thanks all for your replies!

[jamie_clioGTT]

took water pipes off and joined together.. still smokey jo, played with carb, still no joy.. as i said it done this when i first built it and the cure was to go boosting, so guess what i did... went boosting and well, well, well, we have a smoke free turbo :D any ideas ?? will try her in the morning but as a guess she will be fine..

however i have a couple of questions... its now popping and banging its bollocks off when you let off the revs.. is this right? sounds pretty cool tbh but just wanted to check its ok? not sure if it has anything to do with being a bigger turbo?

and also when im in gear and slowing down it feels juddery, rocking sort of feeling. any ideas on this?

thanks chaps!

[R5TURBORON]

Depends what you did when you messed around with your carb. You might have desturbed something and popping and banging alot and juddering can be caused by running lean. Mine did this when i had some swarf in some of the jets

Check the idle jet hasn't got any crap in there, give it a good clear out

Also have you played with the mixture screw?

[djinuk]

check your breather T peice, this should have 2 restrictors in it, chcek these are there, also check for any splits in teh breathers..

Also as mark said, check the carb.

[BluntyR5GTT]

carb needs setting up by the sounds of it fella,

[jamie_clioGTT]

took carb off and the end of my mixture screw had snapped off and wedged in the hole. took it out and replaced just been for a quick spin and its never run so good.. ive now got no mixture screw and blanked the hole off with some vac hose and a bolt..

just one problem now.. when shes cold and ticking over she smokes like a bitch, warmer it gets the worse it gets.. as soon as you drive off it clears..

any advice on this?

thanks all for your time and quality answers :agree:

[BluntyR5GTT]

invest in a new mixture screw fella, then set it up

[jamie_clioGTT]

u reckon that will clear the smoke? dont reckon its turbo? as this is what im putting it down to but dont understand why it clears. if i leave it an hour or so then start her up it wont to do it, 3 hours and it does?

thanks pal

[Bass J]

U need a mixture screw jamie ...its smoking on idle as the fuellings all over the joint :laugh: they are like under £1 anyways from reno ;)

[jamie_clioGTT]

Its the first time I've ever tried one, been using blank off pipe since I built it and its been sweet.

[Bass J]

aye ..go get a mixture screw ...itll run sweet after u install a new one :)

[tubbyG]

So you've Not got a mixture screw on the carb?? No wonder it pops and bangs on overrun. :D

[jamie_clioGTT]

It popped and banged with a mixture screw. Now its blanked off again it runs sweet. But if you read the threa propley you will see that the mixture screw end snapped off and jammed in the carb!

[jamie_clioGTT]

Just took the t25 off and replaced it with my old wobbly shafted, cracked exhaust housed t2 and hey presto. No smoke.

What are the chances of me getting a rebuild kit and bolting the 25 to a t2 exhaust housing myself?

Thanks for all of your help on this matter and well done to all that said turbo fubard!

I personally wouldn't rebuild a turbo yourself as you never know whats actually wrong with it, shaft may need grind, slightly bent, out of balance and without the right equipment to do it you'll be back to where you are now with turbo going tits up again.

[jamie_clioGTT]

ok. advice taken, think ill give it a miss. thanks alot.

[Markey Mark (BD)]

ok. advice taken, think ill give it a miss. thanks alot.

Thats ok mate no worries ;)

[BluntyR5GTT]

you defo dont wanna be taking turbo rebuilds on yourself as mark states theres numerous things that need doing and balancing is really important, i can get your t25 rebuilt for you if you need it done

[jamie_clioGTT]

LOL.. i was awaiting the "you should of brought one off me" comment blunty :laugh: gotta be honest... t25 isnt for me. dont like it. like the t2, you only have to look at the t2 and it spools up, was 4k before the 25 was coming in. thats why im thinking of a t25 compressor with t2 zorst housing.. last longer than a t2 and spool up around the same as a t2 i was hoping? please do correct me if im wrong as like i say im a novice

[BluntyR5GTT]

t25/t2 is a good combo mate, are you wanting to mate the t25 front to a .35 housing or a .47 ? you will have a tad more lag but nothing like a full t25 etc

give me a shout if you want the above work doing, id never be one to say you should of bought one off me mate as we all do our own thing and sometimes we drop on a bargain :)

[jamie_clioGTT]

yer dude i am, hoping for it to last a little longer but spool up quicker. i have a standard t2 knocking about so was hoping to use the exhaust housing off that. get me a quote please dude and drop me a p.m :agree:
