advice, ideas and diagnostics
Turbo Mini Forums

Hi,
I'd solve the problem first. It's no good paying for RR time to sort a problem that doesn't need a RR to diagnose.
I'd be surprised if any RR operater would even put it on the rollers if it smokes like a train

no i will ksit get bill to do the timing.. tapets and carb set up

he will do that on the cheap

like i said james
did you do a compression check ??
this will rule out the bores
did you re torque the head ?? with another wrench to check

my guess its the turbo seals are goosed, IF the above has been CHECKED OUT!
what happens is the seals are old, they get brital and leak oil into the inlet side.
the turbo compresses the air and oil mist vapor and whacks it in to the carb where it mixes with the fuel this is why you are getting white smoke because its oil mist, vapor compressed !!!

do you have another turbo to try out ???
keep us informed

nope havnt done a compression test... have done the head bolts there fine... 55ft pounds using 2 wrenchs

turbo was new 6000 miles ago so hope it hasnt gone

there wouldnt be any water left in the engine from the headgasket going would there? to casue the white smoke

my grandad seems to think there mite beand running it for 10 miles might clear it?

If its not losing water james the that’s fine, in general a compression check will rule the head gasket out .... But you can have gaskets blow in many places oil to water, water to oil and so on .......

The give away here when you think about it was it started smoking before you had the head done by me
So you fitted the new head and it still smokes ..... so the symptoms you gave me i would go for the blower if the compression test rules the bores out ...etc
i know its only done 6k but ... they can fail anytime... have you another to try out ???

hope this helps buddy

nope i dont have another turbo... and me being a skint student doesnt help lol

nope it didnt smoke before the headgasket went... only a little like any turbo car does like minimal amounts

its alwasy ran a little rich as i havent had it set up yet

the head check out fine!
where did the gasket blow ?

see what you rr man has to say

gasket went between 3 and 4 i think and at the back between them

got a video of the smoke to post up later

Take the car for a good long run to see if the smoke clears. It may just be excess oil and water in the exhaust, i have had this with cars in the past.

right the video wont upload!!

but...

-compression is fine
-im not loosing oil
-im not loosing water
-doesnt smoke as much when it first starts up
-smoke a fair bit when you accelrate but when the turbo starts spooling the smoke stops
-the plugs are DRY and black
-the smoke coming out stinks of fuel


recon this just sounds like it need a bloody dam good set up and a blast up the motorway lol

Hi,
Does the OIL smell of petrol?

nope not really...

Hi,
I'd go and get it setup. From what you've just posted up there it's sounds like over fuelling. It may be worth rebuilding the carb before you go, unless it's known to be a good one...
What I'm little puzzled about is why it now does smoke when it didn't before you took the head off...
Cheers,
Gavin :)

well benross did quite alot of work to the head? so maybe that is why?

and it wasnt set up extremly well before

james you cant expect to bolt a modded head on and leave this as before and not set the timing and fueling CORRECT! for that modification with lower compresssion ratio and race valves bigger ports etc ..... that head will flow MASSIVE! amounts of air
THE POTENTIAL FOR POWER INCREASE IS MASSIVE ONCE ITS SET UP

like tom fenton pointed out you need it rolling roaded set up

bat may be right its over fueling
a RR is required

like you say james ........... it wasnt set up extremly well before!!!!!!
please keep us posted

so do you think it jsut needs a set up so stop it smoking...

if it was the turbo it would smoke under boost right? but it stops smoking when it boosts

it wasnt set up well before and defantly isnt now
would that cause smoke?

cheers guys for helping out =]

all the cases i have came upon with the symptoms you describe smoking is the turbo ...... but if its not set up correctley ! this is you first thing to put right
and take it from there.

this is the give away ...... rr firstley ..

-compression is fine
-im not loosing oil
-im not loosing water
-doesnt smoke as much when it first starts up
-smoke a fair bit when you accelrate but when the turbo starts spooling the smoke stops
-the plugs are DRY and black
-the smoke coming out stinks of fuel

yerr i really hope it isnt the turbo as im skint and i guessing a new turbo is goning to cost alot lol!

Sounds like a cooked turbo - is it lagged ? It'll get damn hot if it is.

Suggest two things -

1. Check your breathers aren't blocked - this can cause crankcase pressurisation which could well prevent oil draining from the turbo.

Are you getting the same smoke out of your rocker when you remove the filler cap with the engine running ?

2. Analyse the smoke - suggest you jubilee a white rag (doubled over) over the exhaust and go for a run. If its water, it'll not show up that well. If it's oil, it'll leave a load of crap in the rag for you to take a look at and for you to give it a good sniffing.

Minivanless, but reluctantly happy living with the decision. There'll be another one day.
