I have a question for your all. I have a Fiat Grande Punto 1.4 tjet from 2007 and it is eating 1L oil ever 1000km.
I guess I don't have a leak cause I have seen big blue clouds of smoke a couple of times and no oil on the ground after standing still for a while.
Question, Is it most common that it is that oil header (it might be called valve stem) that is done for or the piston rings?
I have seen a big blue cloud behind my car when driving normal and then have to slow down to because someone needs to turn and then when I look i the back mirror, a big blue cloud of smoke.. Ones, this also happen when I was at a traffic light before I should take off. As soon as I press the speeder the smoke disappear I have only noticed it ones or twice in every 1000km.
My friend have noticed a few times when we are on the highway and I gear down and give full speed that a little black cloud comes out but not all the time.
Also. do you need to remove the cylinder head to be able to repair oil headers (valve stem)?
The Turbo was change under a year ago and some says it could be the turbocharger seal that is causing this?

Hope this made any sense and sorry for my bad English.
Please ask if you need more information

Hi LowIce,

1 liter every 100 liter of petrol would still be considered as 'normal', although quite a lot so I'd say you probably run the tjet around 8 - 9 liter / 100 km and you oïl consumption is therefore too high: proof is the blue smoke …

As it appears mainly afther decelerating, I'd suspect the valves seals: the high vacuum in the inlets (due to engine running and throtle butterfly closed) sucks the oïl thru the seals, get it burn in the cylinders and make blue smoke.
The little black smoke cloud is due to mixture enrichment during acceleration phase, the ECU probably being a bit too generous, or the turbo's response too long...

In theory you should be able to replace the valve seals (the rubber thing, not the bushing) without removing the head, but you better know how ...

BRs, Bernie

If someone here helped You fix -or better, understand- your issue, hit the thanks icon @ bottom right corner, it's free and makes us feel helpy ;-)

BTW if you want to rule-out the piston rings, check for unwanted pressure when you remove the oïl filling cap at cylinder head: engine running you should not feel much "puf-puf" when covering the hole with your hand's palm (warning: HOT)

Also worth looking at is the oil separator. Search for this in the Bravo forum and look for a post by Quick. He took his to bits and cleaned it out.
If this is blocked in some way you could end up drawing oil into the engine under vacuum.

Is then car standard and well looked after? How many miles?

I just got the oil separator changed last month in hope that it would solve the issue.

The car have a Turbo that was changed not even a year ago. I bought it used and I have taken really good care of it but not sure about the other owner.
It have now run 217000km (when I bought it it had run 144000km) but the engine runs smooth.
Only issue is the oil consumption.

I don't drive like a racer but yes it gets a little pedal now and then cause it is still a fun car to drive.. Never give full gas before I'm sure the engine is warm enough. Also wait 20sec before driving if it have stand still over the night, so the engine isn't all dry. I use 5w40 C3 oil.

Was the oil feed and return pipe changed at same time as turbo or at the least, properly cleaned out and checked over? If the oil drain is blocked it could also cause consumption issues. Also, do you know what state the used turbo that was fitted was in? I'd take off pipe from airbox to turbo inlet and check for play.


If separator has been changed recently and all pipes to and from it are clear and the turbo and oil piping checks out ok then it is looking like valve seals.

Let us know how you get on.

Cheers

Lowice, what was finally your problem?
