far too much white smoke coming from my 1.4sr when its running, especially under load, held it at 4000 revs and the street filled with smoke. have been using lots of oil as well, and i would guess that is linked. any ideas? the head gasket was done 3 months ago.
cheers
only under load?
dead piston rings ;)
it would be blue smoke if it was burnin oil. i rekon its water.
Wills "rally" engine poured white smoke out when it was gunned. it had near full power but it left a hefty WHITE smoke screen. and thats deffo the bores on his.
that and/or you cocked up refitting the head gasket lol
sounds like piston rings, but failing that it could be that the headgasket has gone again! did you have the head skimmed when you changed the headgasket? and did you torque it down properly? 8)
just a couple of ideas

did you use new head bolts when you did head gasket ? essential.
also is making sure that block was thouroughly clean around the oil and water runways at the end of the block, to the left of no 4 piston, befor fitting gasket

they guy i bought it off had done the head gasket, because it had been overheating. he get it done at a garage and had a recipt for ?200. is that a price for it, or could it be a shit job done on the cheap?
is there a way of checking if its the piston rings?
take it apart.
?200 seems ok for a garage. that's what they'd charge.

If its oil then it will be blue smoke, if its white smoke/vapour then its water. If you said its losing oil, and water is getting burned, so it sound like Head gasket.
worn piston rings won't really cause white smoke

my XE had worn rings and cracked valve guides and it was white smoke it was chucking out
only had a VERY slight blue tinge to it at certain times, although it did smell like oil
i thaught it was the head gasket originally until i had an engine builder look at it and he said it was oil for certain

head gasket / piston rings / valve stem seals IMO

can u do any tests to see if the head gasket has gone?

Look for a white creamy type substance in your oil, also milky stuff in the water, should be the easiest way of tellin that the h/g has gone
Do a compression test aswell. prolly the best bet, 5quid at your local garage

no creamy stuff in the oil or water, i hadnt checked the water for ages and it was only full to the bottom of the water container under the bonnet, and as i said been eating lots of oil. started it 2day and there was less smoke, but still more than usual. well perhaps will get a compression test done. if not then it must be worn piston rings. i take it they are quite expensive to change and not a DIY job.

if its white smoke then its not rings is it ? water does not leak past rings unless its coming in from the top.
to satisfy yourself its not the rings do a WET and DRY compression test.
do a compression test on each bore and take the reading, this is DRY.
they should be all in 20% each other, if one is down then it could be hgasket,rings or valves.... to confirm it is rings
do the WET test
squirt one shot of oil from an oil can into each bore and then turn the engine once by hand to work it in.
now do the compression test again and take the readings ,,, if there are significant increases in readings it means the oil you squirted in there .has temporarily sealed the leaking rings.
FFS oil can burn white!
ive seen a foocked bottom end burning WHITE like a mofo
jeeeze haynes manaul isnt always right!

Guys open you minds a listen to camb, he knows what he is talking about, not all oil is blue!!! never listen to the haynes manual is rubish..... could be anynumber of things, really need to see it or be told more before it can really be diagnosed, theres no black and white, ever heard of gray area's???

who effing well said anything about a Haynes manual ?I dont need
a sodding Haynes manual you patronising git.
multigrade oil used in a Nova burns blue unless it is mixed with something, its the law of physics so why don't you open your mind and with a bit of science.
if its burning white its because its got antifreeze in it.
Of course it could be any other of things, thats what the forum is for (i fink?) to get genaral ideas. Not for use to rubbish other people's comments.Obviously must be pecking order here with Camb as the Alpha male who everybody worships and don't speak till they are spoken to..
I get the picture I'll sod off
i dont even wnat to consider to be the "alpha male" you tit.
its jsut we KNOW the rings are gone on a certain engine and its pluming white smoke out. and the head gasket isnt/wasnt gone.
the oil was the semi synth.
when bigruss threw a Cv joint at trax the gear oil coverd the exhaust and burnt white.
chris t's car with not the best pistons tends to blow oil when its running at max chat and thats a greyish white. not blue.
if the headgasket had gone then it would chuck out white smoke all the time. even on rundown. but the guy said it does it at load, which is a very good indication of ring wear (ohh err missus)
get the head off, and get the bores checked. if its not the bores then so be it. but its not an option to rule out.

easy there STEVE STUMPY!, all i was saying was that just cause its white colour doesnt mean it head gasket that most people were saying it 'could only be'..... :?
head gasket = smokey all the time
rings = generly under load
stem seals = maybe would centainly get worse underload...
porus head..... it may be that the gasket hasnt gone at all and that the head has gone porus.... never heard of that on an SRI tho, not impossable tho...
oil leak???? = onto the exhaust maybe
depends how much oil and how its being burnt.....
Just idea's mind
