so like 3500km per week?and a litre of oil? sounds pretty bad but its lots of km/litre of oil. valve stem seals have jumped out of their place? i had just the same fault, oil consumption.
there is no leak under the car?

cos in vaux its a typical fault. they will jump out othervise. and many guys have said to me that if the head is in its place while doing valve stem seals, they will jump out cos its impossible to get all of the oil out of underneath the valve stem seal and if there is oil it will jump out... i had mine done 10000km ago and just got my car off the garage* total rebuilt, full head rebuilt, piston rings, bearings on downstairs, everything...*, and always use vaux own valve stem seal dont go for cheaper, cos they will wear in no time. valve stem seals will only give smoke if there is enough rpm, f ex. hit the pedal with 1 gear and go till redline change to 2 and get somebody to look at, it will give smoke near redline and when chancing..
and do something to it cos what happened to me is that the oil went too low sometime and bearings in downstair got too hot and were fcuked, pistonring too... it was near that if i had drive like 2000-4000km more it would have been like new engine or so...

glue is something very special, couldnt find out what they used, but something like superglue wont work
its something wich can handle lots of heat and oil...
maybe someone knows?

mine did give nice puff out when starting...and when flooring.

but if it does consume oil it has to go somewhere...
but it did irritate me and was good that it did, cos it was at the last moment...
but youll never know, might be something harmless, just taking some oil, no one knows for sure, until engine is in thousand parts.

i know and to get the engine in a thousand parts wouldnt be worth the labour costs
i know its going somewhere dunno where though doesnt make sense because literally its the cleanest looking air comin out the exhaust not a tint of grey u cant actually see anything coming out the exhaust and there are no leaks whatsoever.

yes when my car was idling *and drinking lots of oil* there wasnt any kind of fumes just pure exhaust, but when flooring its was different thing...
what i can say now its expensive around £700*dont know sure yet*
but was definately worth it in my case... its lots of money* and all out of something else...* but now its lot differend in sound, there is no othere sounds just engine running, if you know what i mean.
also feels lots healthier when driving.
but as i said it can be something harmless...
in my case it wasnt, it was just before it was too late.

Hi mate ive got EXACTLY same problem as you!!!!!!!!
my Gsi 1994 which has done about 80,000miles so far, has got same problem as yours!??? but mine leaks if i top it up over the max mark!!
the oil just goes! the engine is a mess can see the oil lealing from gaskets and the gear box area is covered in oill!!!
only smokes wen i floor it to the Redline!!!
ive noticed the oil gets lower quicker when i drive at higher revs, as i have been driving on a lot of motorways lately!!?
ive heard the Gsi corsas are common for these oil problems, my mates one had same problem but he never bothered fixing it and the engine just packed in, had to get a new engine conversion!!!
i was told that my head gaskets and valve stem seals are gone! and the bores and piston rings shud be checked to!
hope its sorted after this???

its problem with corsas 1.6 engines especially*also with earlier 2.0 engines.*
what is a cure to yours problem is:
get the WHOLE head rebuilt, get them to check everything in it, cos once its engine open its not that much cost to that anyway.
ask them to glue those valve stem seals to head, if they are not familiar with it, go somewhere else. cos this is what causes the most of the problems, otherwise they will jump out and oil level gets low -> worst option is transplant if it goes too low...*mine was almost there*
once the head has been taken out, ist so little more to check pistonrings and bore too, cos if oil has at some point dropped too low, f ex. in motorway, it might be so that pistonrings *worst is the pistons themselves*has fried, and if you dont check them at the same time, oil consumption stays the same, if they are fried.
and with the miles you have id still get them changed cos it brings some lost power back, its not much £ to that if you are doing the full package. i didnt go for vaux parts, i get from nameless manufacturer, almost same quality but less money spent.but dont go for the cheapest pistonrings.
and last but not the least its very important at this point,since the whole engine is in parts anyway, to check downstair bearings, doesnt cost much, but if they have suffered ist good to get them there too, mine main bearings had gone too hot at some point and had terrible marks on them...
it will cost but its definately different engine after that...
and when doing that youll get all those oil leaks out cos if its in parts,youll have to put new gaskets in all places.

ok so basically i need to....
1-basically whole head needs checking and if so rebuilding
2-skim head
3-head gaskets
4-valve stem seals+glue them to the actual head
5-check if bores ok
6-bearings
7-piston rings
8-worst case actual piston rings need replacing
best to use original vauxhall gm parts
and after all this my car shud be perfect right???
is this all correct or need anything adding,if so please let me know???
as this is what im gonna tell the garage so that he knows what im talking about and doesnt try rip me off!!
how much will this all cost roughly???

plus obviously all engine gaskets and new head and con rod bolts. might as well get them to check dowstair bearings too and get new ones if any sings of trouble in there.

loads and loads. Your basically having a full engine rebuild if you do that. Take it back to who built the head and see what they say. Did they check the bores when the head was off?
If your doing 14,000 km and losing 1litre of oil then there is no problem. You shoud be changing your oil every month as well.
Valve stem seals shouldnt be gluded in place, they are not designed to be. When valve stem seals leak, they leak through the hole the valve goes through, not through the connection to the head. If they come off then they will virtually be pushed back on when the valve cgoes down anyway.
I use a bit of oil on my freshly built engine, when its been on a rolling road above 7k it smokes quite badly, the tuner said not to worry and he reckons its coming from the top end (i used cheapo stem seals)
Check the spark plugs.
If there is no smoke and no physical leak then something odd is going on!!!

yea theirs no physical smoke really, but yes i can see the whole engine covered in oil!! so theirs deffinatly some sort of leak from somewhere, i reckon its the head gaskets, also oil is getting in the cylinders coz spark plugs were gunky like??
