right basically my headgasket went a few months ago... so i took the head off... sent it to benross had the work i wanted done as the head was off... put it all back on... changed oil let it tick over for about 20 mins... then took it for a lap round the block... then i changed oil again... but it is smoking alot from the exhaust

the smoke is more thick and white rather than thin and blue

do you thinkg something worse than just headgasket has gone

or jsut need a dam good setup after the head work and change of headgasket??


your help would be really apriciated

regards

james

Hi,
Thick white would suggest your "burning" a lot of water in there.
What happened with the original problem?
Are you losing water now?
Was the head skimmed?
Is the exhaust full of water from when the head gasket went last time?
Is the turbo a water cooled one?
Is the inlet manifold a water cooled one?
Basically any where water can get into the combustion chamber.
If none of the above you could have a cracked head...

Gavin :)

Hi,
Pull the plugs out after a bit of a run.
If one or more come out looking brand new, that's your problem!

Hi,
Well yeah, the clean plug basically means it's been steam cleaned!
If it's only one plug could well be a cracked head :(

May be worth re-torquing the head down with another torque wrench, yours could be out of calibration?

oh soooo either way its bad news lol.. im gona get it set up by bill richards as he is close then if it is still abd then i will have to re think things

i dont think the head is cracked... well i hope it isnt... i jsut rmebr i didnt flush the oil cooler out so maybe still water in it?

but surly not if ihave doen 2 oil changes

it seems to run ok.. well as good as it will till its set up but jsut smokes lots!!!!

firstley the heads fine ...i can assure that!!

if its NOT losing water then its an oil problem

next you need to do a compression test to determin if the rings are goosed

if this checks out ok..?
then the problem will lie with the TURBO!

your torque wrench is it callibrated right.. ?
far too often people on this forum have fallen in to the trap of a ... craped out torque wrench giving a lower reading than its set for .... peeps often blame the head gasket warped heads ....etc on this common fault :(
the head shoud be torqed to 55ft pounds and use another torque wrench to compare

let us know how you go on

I thought that I was the only dummy that used a dodgy torque wrench.

It's worth a check though, as I got through 3 gaskets before I found that my wrench was cracking off at less than half of the set torque.

In the 13's at last!.. Just

so maybe the headgasket has gone again which will mean smoke... what im gona do is wip the head off... and start over... new gasket new oil and use 2 wrenchs... i will take my grandads snap on one and the one we used which is teng tools i think..

recon the headgasket could of gone again?

Hi,
Do a compression test (dry and wet) and a leakdown test too if possible. See what you've got.
Although Steve has said the heads not cracked, you can't be 100% sure.
I've had a head pressure tested fine, only for the crack to open up after running for 20 minutes then it smoked like a train.
Not trying to rubbish your work Steve.

just had my firend round who is admin on punto sports and runs a very fast punto gt... knows his stuff about turbos...

he thinks the turbo has gone...

the plugs are black tho what does this mean?

also... the smoke smells very fuel like... and the tapets are not done!

so maybe a good set up might sort thigns out?

or wouldnt that make lots of smoke?

Edited by jamz on 20th Jun, 2008.

black and dry or black and wet?

if they are dry and sooty it could just be rich, if black and wet (oily) then its.... oil.

pop the boost hose of and see if its oily in there, if so its the turbo.

they where dry... so maybe jsut over fueling alot... and the fact it need a dam good set up would this cause smoke? cos it doesnt seem to be loosing any oil or water

i wish i had more know how

Why not add your location in your profile, there may be someone nearby to take a look at it for you.

I've never seen a car give clouds of smoke due to being too rich,

if its oil it wont take much to make it smoke, little enough that you wont notice the oil level drop unless you frive it for some time.

also oil smoke can seem white to peaple that are not familiar with it, water smoke is white and cloudy (just like when you start on a cold morning) oil smoke can be a light sky blue and "hangs" in the air a bit more.

if all else fails and you get really stuck with this, does your brake pedal creep at all? if it does whip your master cylinder forward and check inside the servo for any fluid. if there is change your master cylinder. this will cause smoke as well, although the way you are talking im not sure it would cause enough, but alot of smoke to some could be different to others.

anyway like i say thats an outside chance if you get really stuck and youve checked everything else, check the easy things as above first!

if i take a video then i will post it... sunday tho

Hi,
A lot of excess fuel will cause white/blue smoke, try shutting the fuel pump off and see if it clears....

Gavin :)
