ok another question

on start up would which one would cause blue smoke witha quick blip of the throttle from cold?

and when moving slightly on bost and loads of blue smoke

im thinking more turbo now

mechanic28

iTrader: (5)

does it smoke badly when on boost and when u back off?is your turbo makin a siren type noise?

xr4x4rs

iTrader: (5)

turbo sounds like normal, but i know the noise you mean

when i let off there is a bit of smoke on over run, but when on full chat it will fill a dual carriage way up

dave green

turbo can be checked simplely by checking up and down movement on the inlet fan of the turbo

its the turbo police

xr4x4rs

iTrader: (5)

just minimal play as you would get as ive checked

that would only tell me that the bearing is fine though

as its the smoking issue thats causing all my problems

mechanic28

iTrader: (5)

so smokes badly only when on boost

Oranoco

Is this on your Escort have you tried looking at the valve stem oil seals?

xr4x4rs

iTrader: (5)

only smokes when on boost yes

not on my escort on my cossie

Oranoco

Can't help then as I don't know too much about them

mechanic28

iTrader: (5)

well imo if it was piston rings u would have smoke on and off boost!sounds like turbo to me

xr4x4rs

iTrader: (5)

see thats what i was thinking

but then i thought as the cylinders are being pressurised by the boost i thought that it could be the rings that have gone

but im more towards the turbo now will take it off and send it back for inspection on wednesday then

Dan

Blue Smoke is Turbo on a Cossie mate, for sure!

Just had this on the way home from ND yesterday on my mates T34!

Carlsworth

play in the shaft wont make it smoke
smoke is the oil getting past the rear seal and into exhaust system



has the turbo been rebuilt recently?
will be under warranty then?
if it has, then the turbo should be right, and id look elsewhere first before sending it for inspection

xr4x4rs

iTrader: (5)

turbo is a week old

Dan

My mate's did 600 Miles mate, but was fucked due to oil starvation!

xr4x4rs

iTrader: (5)

compression on all cylinders is fine aswell

but my water does smell of oil

xr4x4rs

iTrader: (5)

mine hasnt done 200miles

mechanic28

iTrader: (5)

maybe to a compression check first?but would still say it a turbo problem wot spec your cossie at?

Dan

Not sure then mate, my mates old engine was cunted thanks to someone on here but then there's not alot you can do about that, 'meant' to be a 6k block! My ass!

Did NO miles though and it still took the turbo with it!

You live and learn though hey!

Carlsworth

how many miles has it done exactly since rebuild, and how long have you been driving it at a time....

it COULD just be oil in the ex system from last turbo if it was badly smoking before...

take it for a long run and see if it sorts itself out..


carl

compression is 140 across all cylinders so i know the compression is ok but this doesnt show oil rings as i need a leak down test to do this and i havnt got the Ł60 at the mo to have it done

i was driving the car about i took the engine out of and just replaced the headgasket on it and bought some new stuff

xr4x4rs

iTrader: (5)

the car has been on the road just over a week

the orinal car was std rite down to teh exhaust and was running a t3

alls ive done is fitted a grp a gasket and put this new turbo on

i bleed the turbo up before firing the engine up, and ran itin for about 80 miles as i wanted to get used to the car again

after this the fuelling was checked and set and the boost increased to 25psi

couple of days later it started smoking really bad

and is just getting worse, ive done an oil change aswell and still no difference, breathers arnt block and everything is faultless bar this smoke,

and its costing me an arm and a leg in oil

Carlsworth

then get it sent off for inspection, they will see straight away if its been leaking past rear seal

why its split, get them to fit a staggered rear seal
will help no end

mechanic28

iTrader: (5)

silly question but u say it was standardnow u running 25 psi so u running dark greens yeh?with group A headgasket?t34?correct wot else have u fitted to run this boost level?

xr4x4rs

iTrader: (5)

ok

my spec is

std 4wd cos engine
grp a gasket
spec-r grp a breather system
t35..63 exhaust housing
rs 500 intercooler
turbo coller
samco hoses everwhere
bosch 044 fuel pump, new filter aswell
mongoos exahust
k+n induction cone filter
green 803s
3 bar map sensor
level 8 ecu


the spec is ver reasonable and was the same spec as my last engine

tis engine has been running std all its life until i put it in my car
, it ran 15psi for running things in , then was put up to 25psi

mechanic28

iTrader: (5)

cool just had a thought u did not fit a oil breather kit wot grade oil u using

xr4x4rs

iTrader: (5)

im using castrol edge 10-60 i think it is

Tev

iTrader: (2)

Still no joy fella

Gutted 4 ya

Fingers crossed its just an oil seal gone

xr4x4rs

iTrader: (5)

hope so mate

taken turbo off tomorrow night and is being collected wednesday

AAman

I've just had exatly the same problem... fine on start up, fine on light loads, and normal driving. As soon as it's on boost huge clouds of smoke...
and only after i fitted a new bigger turbo..

I checked the turbo and all was well..

Then i pulled the head off and found nothing unusual..

Then i pulled the bottom end apart and found no.3 three oil control ring was broken.. And this was on an engine that had apparently just been rebuilt...

Hope yours isn't as expensive a job to repair!

xr4x4rs

iTrader: (5)

well turbo is being inspected for free so if it isnt the turbo engine will be coming out and the bank account being emptied again

xr4x4rs

iTrader: (5)

i took a pic of what it looks like at 14psi lol



triple the smoke contecnt when on full chat

JonnyBravo

Could well be rings mate, I hope for your sake its not though

My mates is nearly as bad as that and he changed his turbo and it made no difference.

Atleast you can have your turbo inspected for nout though

xr4x4rs

iTrader: (5)

JonnyBravo

i do hope to god it is

its like that on over run aswell but disapperas

car is fine when not on boost, just starts to smoke when the turbo is just kicking in

if its not the turbo then im sure i can sort something out regarding an engine rebuild, and may aswell go more power or at least build it for more power for a later date

JonnyBravo

I think you mean

I hope to god it isn't

xr4x4rs

iTrader: (5)

i meant i hope to god its the turbo

im going to cry if its the engine

R5FORD

iTrader: (1)

my turbo went straight away

so had to fork out another grand to re build it but now its something spectacular

xr4x4rs

iTrader: (5)

ok little update

its not the turbo, this is in perfect condition

so now im looking at rings, or valv guides

if not any of them i havnt got a clue

Paulo P

Gutted I hope you find out what it is soon and it doesn't cost you too much
