ive been through some ups and downs with this car but im sick of this now. as some of you know i recently converted from auto to manual but i have to say i dont even want to drive it anymore. thats a real first.

the whole thing feels disjointed clunky, im pretty sure the turbos have shit the bed i took it out tonight and it stinks of oil and chucks out white smoke when it feels like it. every time you pull away it rattles and feels like it wants to stall. i can honestly say two weeks ago i had a very solid auto jdm zed. now if im totally honest i have a smokey piece of rattley shit. i need help or im gonna burn the thing to the floor.

Hope you get it sorted Steve and with the help on offer I know you will. Keep the faith:clover:

 

Seconded.....

 

.....if it was working fine before the conversion then it's probably something minor; or something that was not done properly during the manual conversion.

 

Good luck mate; don't lose heart!!

i gave you a shout earlier ian, your girlfriend? answered. anyways when you pull away from prolonged idle its alot of smoke. however if your out and about and boosting without coming to a full rest it seems minamul. even on full boost. the deposits where dry not wet, and where abouts should i check within the pcv system?

You rang when i was out talking to cyberbean, give me a ring now bud.

After a chat with vodz and ultimateray and hellraiser I feel more positive. Few things to go over yomorrow as im working then off to wales this avo. Then we shall see. But even if this requires me to pull the block and rebuild it im going to get this car back to hoew it was if not better.

done the neutral switch today, and reset the idle. the car now idles between 7-900 with the idle control valve plugged in and 550 with it unplugged. ive not had a chance to drive it yet, but it certainly feels a bit better going up and down the drive. it sounds much more like a v6 now than a highly strung 4 pooper. and on idle there is minimul if any smoke. raising the revs .up at a standstill causes smoke to start billowing out though still and once idling it will eventually clear. i think i nee dto take it on a damn good run before i can say its def still smoking/

right took it out to get some fuel today first drive in over a week.

alot smoother on take off but not perfect need to check the actuation of the neutral switch and the timing.

idle is far far better.

smoke is still present however it now smokes far less. i only get smoke on boost intermittently, and on intial pull away after prolonged idle.

im gonna take it for a proper drive this evening after dinner get it warm and burn the accumilated crap out the system see if that futher improves the issue. :D fingers crossed but im still fairly convinced that the turbo rear oil seals are on the way out.

right took it for a whiz this evening, MUCH better. Runs much smoother however there is white/bluish smoke on the over run. and occasionally if prolonged idling like behind a red light a puff of white might come out. the first pull on boost chucked out loads of crap. but the more i boosted the less there was.

i think a leakdown test may be in order. and il try to get some videos of whats going on on here over the next week to help with diagnosis.

Good to hear Steve, will have to meet up soon mate.

yes mate il give you a text regarding what we were discussing the other day tomorrow. :)

right had hellraiser round tonight we let it warm up and took it for a spin. at idle it barley smokes, first few boosts produce smoke and its actually a pale grey blue and heavy of oil smell. under general load it again barely smokes, it seems worst on low level rev overrun(high revs are fine) and when pulling away from a slow down at town speeds.

we even gave it a good blipping when stationary and warm which produced very little. this keeping pointing out turbo and no turbo related syptoms.

any ideas guys?

There are a lot of incorrect answers here... but for the most part, you can hold true to these: Blue smoke is primarily from internal engine wear. If it's constant when the engine is on, then the rings etc are worn and need to be replaced. If it only is blue when the engine is cold or first started, the rings are worn but not gone completely. You get the oil seeping during the night and it burns off when the car is started in the morning. Black smoke is a fuel/air mixture suggestion problems with injection or carburation. Cause of black smoke is due to running rich in the fuel air mix. White smoke can and DOES come from coolant burn off in the oil due to a leaking or blown head gasket, cracked head etc. If you aren't sure or you don't know what you're talking about, don't advise. Wrong advice can be more damaging than the actual problem.

White smoke is caused by engine coolant/Antifreeze being processed in the combustion chamber(s) of the engine.....ie burning, melting, frying, whatever....Period....I'll explain further.... This is automotive chemistry 101....Oil of any automotive type burns blue.....too much fuel issues burn black not enough fuel issues burn grey on a cold day you may see what appears to be white smoke from the exhaust that will disappear after the vehicles engine has warmed up to it's normal operating temp.. This is a normal reaction called condensation... condensation is the result of a small amount of water/dew being drawn into the exhaust usually collecting in the muffler and/or the catalytic converter and is caused by our friend mother nature..... like when you see your breath on a cold

wiki answers

sorry should of deleted some of the text before pasting wiki answers are the source

thats not strictly true though is it. although a good guide. pcv's can jam introducing oil into the combustion cycle, causing blue smoke. oil can be deposited post combustion via turbo oil seals causing oil vapour which is a whitish blue colour. raw fuel can be dumped into the combuston chamber causing again white smoke. so not golden. i am going to do a compression/leakdown however to be sure. i did do it about 5k ago and all was well.

right aftertoday inspection the foloowing has come to light. a leaking pcv valve that is causing oil to drip over the left hand turbo and possibly into via the top feed. also some not fully tight spark plugs that had oil coming from the rocker cover down the shaft in very small amounts. the spark plugs were clean an amount of carbonation which is obviously to be expected. no oily deposts. the plenum had very little oil in it.

the car will idle quite happily, well very happily actually, smooth as glass. with no or very little smoke. at 2000 rpm it smokes like a trooper at 3000rpm the smoke clears.

hellraiser kindly made a video of this today aswel which quite cleary shows the above.

video of smoke issue.

cheers gaz it all looks so promising till the revs start to rise lol.

can a mid put in the thread title that this now has video?

Could be a lamda sensor?

evening bump.

lar de dar no one talking to me anymore?

have you done a compression test yet?

we tried but the equipment wasnt working correctly. its on the list this week. i did however do one less than 10k ago. and although i dont remember the specific result i remember it was pretty good. il have it done by the weekend.

just remember

 

Minimum 143psi max 184psi with no more than 14psi difference between cylinders.

 

That does look a lot of smoke though, similar to my zed with the blown head gasket, stupid thing is with how the engine runs you would be forgiven for thinking it was something else as its lumpy once running, only on start up?

:S sorry you lost me there you think its lumpy? it has got full decats and divorced downs, i thought it sounded pretty damn smooth, and that was well not hot but warmish. it will smoke like that a idle only. once moving ie under load the engine does very little. i think whatever is getting in there is dribbling out at idle but not passing through. then once the revs rise it starts to pump it out the exhaust. once pushing it out at a faster hotter rate it burns off what was introduced. that is my sorta take on it.

Is it deffinately smoke?

Not steam by any chance?

Was there an oily smell during the test video?
