freinds frst is smoking on start up, was serviced today with new oil an filter etc, and he cleaned the oil breather filter out with petrol, he said he'd filled it up with petrol and left it to sit so it would clean itself of gunk, and refitted added new oil and started car and it was smoking blue from cold start and clouds of white.
Went to have a look as he said its only from cold once warmed or he takes it for a drive and it warms up theres no smoke, even when booting it on dual carriage way or on long stretch theres no smoke.

so why has it started blue smoking, he said its thick clouds of blue an white smoke, and it comes from exhaust with the wing blowing it comes from under the car, even fills up inside the car abit apparently aswell????

any ideas, i though stem seals, but aw it with my own eyes, was like a smoke machine, but once warm not 1 hint of blue smoke at all.

so any ides on this at all peeps?

cheers in advance

Valve guides, they are not a mayor problem. All cars start to smoke when you fire it up the first time every day when they reache +/-150000KM, some earlier some later

[RScrew69]

but it has never ever done it before, it just started doing it now straight after service, do u think it could be the oil he put in which was 10w 40 i believe?

cheers

Do a hot and cold compression test mate. Only way to rule out a cracked block, especially if it's a crack that closes when the engine's warm (stranger things have happened).

okay he said more than anything its thick cloudy white smoke on startup, but then after 2 mins it clears, and it will not smoke 1 bit after not blue, white or anything, its just on starting from stone cold?

don't think the block was cracked when he started it to do service he goes he just started it up put on drive on ramps, dumped oil etc, put filter on new oil in left oil black breather pot filled with petrol to soak outn changed his fuel filter, started it up and it done the clouds of thick whitish smoke very cloudy and again after 2mins of being on ramp, cleared up and nothing afterwards even when he boots it or backs off theres no smoke at all

strange or what

got me stumped, i just said its probably ur stem seals and the black breather pot

cheers

Perhaps a small gremlin inside waiting for the engine to start to light his fag.

Or

Valve stem oil seals - cheap to fix, recommend a garage does it though.

Cold start up smoke = valve stem oil seals
Hot running smoke = turbo oil seals.

Happy days people.

[RScrew69]

cheers mate will tell him to get them changed asap, bewildering isn't it.

cheers

[RScrew69]

i remember someone saying something about the rear oil seal on the turbo? any truth in that?

Also been told to tell mate to check and clean all breathers, what exactly are the breathers or how can we clean all the breathing system out?

cheers

[mrviper]

sounds like he thinned the oil with the petrol and its ecaping past the rings / stem seals

just an isea thats not been said yet !

[RScrew69]

hi mate i'll let him know that sounds like a very good idea. might tell him to change oil and breather pot an tem seal and see if it cures it

cheers

The only breather pot (black at the back left of the rocker cover as you look from the front) has three pipes coming from it and has a diaphram and gauze in it.
Clean it with washable degreaser by spraying inside and shaking it like hell, covering the holes with your fingers.
Then wash it through with water and dry it thoroughly using a hair dry if neccessary.
There is another breather pipe in the same place, but on the other side of the rocker cover at the back. This goes from the head to the bottom of the block, but is very difficult to get to and being a straight pipe, it is unlikely that it will get blocked and need cleaning.
10w 40 oil in the engine is fine as far as viscosity goes.
The breather pot is never cleaned out in a normal service at your local garage, thats if they even know what one is so garage sevices are poo.

[RScrew69]

breather was cleaned cos it had gunky oil dripping out the side of it.

had an idea now after speaking with some peeps, going to clean the oil pick up pipe in sump wash and clean the sump out so theres no crappy oil residue in there, clean the breather in the sump in bottom end, clean all pipework associated with breathing or buy new piping, replace valve stem oil seals, stick bailey oil breather system to car and will see how it is then.

does that sound like a good idea? as we say it was only on startup from cold its smoking, after that an shes warmed up she stops,

cheers

p.s whats the breather look like in the bottom end?

[RScrew69]

anymore ideas, stem seal were replaced but hasn't made abit of difference, am pretty sure it is something to do with oil sitting at the back of the turbo when u switch car off and its burning that off when u start it from cold, can anyone confirm this theory?

cheers

[RS_Rawli]

id say turbo

will get worse, and smoke for ages, mine did it, started off with a little puff of smoke in a morning, now its virtually undrivable when even remotely cold

[MAD_Adamski]

my rs used to smoke on start up every time.... every car does its the auto choke my vr6 does it wen u first start, but.... it depends [ERRR] type of smoke???? only 2 main faults either turbo or engine!!!!!! so i'd let it warm up then wen its hot rev it and see [ERRR] colour smoke comes out to determine whether its engine or turbo?? the funny thing is its been a while since had mine workin so can't remember if its blue smoke for engine and white for turbo??? or vice verse lol... but u'll know then as i put a new engine a a turbo 8 months old from turbo technics and it seemed to run ok then a mechanic mate told me it smoked too much for a rs??? we found the turbo had gone cause it had been over boosted..... but [ERRR] way hope this helps... ad

[ianFRST]

id say change the oil again dude.

id never trust a garage 2 do my oil again. my car was fine till i got an oil change, next day the turbo went. may seem strange but i only drove it home from the garage.

[RScrew69]

hmmm its annoying, the other thing is THE CAR DOES NOT SMOKE WHEN ITS WARM AT ALL!!!

i've seen it and some times the smoke seems abit hazey kinda blue and then sometimes it looks like thick kinda cloudy white smoke, alot thicker than the condensation smoke u would get on startup.

we've checked around the turbo and theres no oil seeping out of anywhere and theres no play in the shaft so turbo seems fine.

Reading through previous posts i think he might be getting his oil return modified so bigger pipe and returning it direct to the sump.

cheers

[MAD_Adamski]

to be honest dude i think ur worryin about nothin!!! a turbo is always gonna smoke on start up some more than others!!!

[RScrew69]

its embarassing though, like we went to pub on weekend had a pint, started car as it was cold, and filled the car up with blue smoke, so he just drove off without letting it blue smoke to much, but then once warm never puffed anything even when he switched it off to by ciggies from petrol station etc.

bloomin annoying

[MAD_Adamski]

i know [ERRR] u mean but as i sed mine used to blue/white smoke on start cause of the choke then once warm was fine!!!!
and my xr did smae thing its cvh for ya dude there fine wen warm...

[M Brian]

does it breather heavy out of the oil filler cap or dipstick if you take them off when the car is running?

I have similar problem at the moment.

if I have the breathers connected it billows smoke out of the exhaust... really really smokes... even when warm but only at idle.

if I disconnect the breathers so that they are open to atmosphere I get NO smoke from the exhaust... only from the open breather pipes.

I think that the rings on mine are worn. not sure though

[t2rst]

does he let it cool down properly
ive found with my car if i dont let it cool down properly it will puff a bit of smoke when re-starting her from warm or cold

basically dont turn the car off if the fans still spinnig wait for that to turn off then turn the car off

then try re-starting her again
do this when its hot and cold

[~Tony~]

yeah cooling down and warming up is a key thing with turbo's

[RScrew69]

he does let it cool down properly he's a fellow enthusiast aswell. When u take the oil cap off theres a little bit of steam kind of puffs out, but nothing else at all after the 2 puffs, but i think hes going to be buyinh a bailey breather system for it, as another thing thats cropped up is the posibility of to much crankcase pressure, so thats going to be cleaned out aswell, think hes getting some cash together for the time being.

cheers peeps
