White Smoke...

[dc2r-0636]

^ rich is black smoke.

Op, don't stress sounds like condensation.

Rich is black smoke, oil is bluish-black, white is water.

If it's only happening on startup then relax. As people have pointed out, it's condensation. When your motor cools down the exhaust caches a bit of water the same as your house windows do at night. When the exhaust heats up, it gets blown out the tailpipe. You'll see a lot of cars doing this in the first 5-10 minutes of driving.

If you are worried about a blown head gasket (which I wouldn't be if the issue goes away after 10 min of driving) then get a mechanic to run a blow-by test - checking your radiator for gas blown out of the cylinders into the radiator.

Well Hondas are designed to run rich on startup, does the fumes smell?

Oh god, I forgot I grew up as part of a generation where we had to use a manual choke

Just tested it again this morning.... the white smoke has reduced a fair bit, i was initially only worried because it smoked A LOT, like what you would expect when a house was on fire and smoke was coming out the window.

But when i did check again this morning the amount of smoke amount was a lot less. Which i find strange because it was a lot more ****ing cold last night than the previous 4 nights. OH well... ill keep monitoring it and see how it goes and just pray it was just condensation. The smoke does go away after 15 minutes of complete idle or 3-5 minutes driving. I just want to make sure that it would be safe for me to keep driving and i'm not making it worst by driving.

And yes the fumes does have a smell... not too sure what it smells like in particular...

Another problem i came across is though i hear ratting in my exhaust I THINK... as if its loose or something? Not too sure, while i was testing the car for white smoke this morning i reved it up to about 2-3 to see if it would cause white smoke as i was suprised there wasnt that much as i expected and i heard rattling noise like rocks in my exhaust or something??? Whats up with that? Any clues

My brother's pulsar has the same issue with smoking in the morning, Its not condensation i tell ya. It blow heaps of white smoke in some mornings that it goes into the next door neighbours yard. I did some research and apparently White smoke in the morning is caused by oil leaking into the combustion chamber overnight. His oil is not milky aswell as its fine, so is the coolant.

So we concluded that the engine is worn out seen better days and it needs to be rebuilt. For now, we use thicker oil and that seems to help abit. It DOES go away after its warmed up. Although I'm not sure if you got the same situation.

Sounds like you should take it to an exhaust shop - might be a broken mount, broken baffle, anything.

Condensation doesn't increase due to it being more cold. Some of the by-products of exhaust fumes are hydrogen and oxygen which bond in gaseous form. When your car cools, these move from gas to liquid state and ends up sitting in your exhaust, cat etc (which is why exhausts are prone to rusting out over decades). When you re-start the car the next morning, the exhaust heats up quickly and has more H20 being pumped out as steam due to the build-up. Then it reverts to normal once all of the residual water has been expelled from the system.

Ignore "fumes smell"... all fossil fuels smell. In fact, you shouldn't be deliberately smelling an exhaust given all of the carcinogens etc that are being pumped out of an exhaust. If you wanted to see how much water comes out of a tailpipe, start up your car from cold and put your hand over the tailpipe- you'll end up with a sooty, wet hand. Don't leave it there too long though and don't breath in the exhaust fumes.

Your research is faulty. Oil burns blue. You and your brother need to check your facts. Thicker oil makes absolutely no difference other than as a placebo effect.

Could mean your cat converter is breaking inside or your heat shield is rattling on your cat converter. Best to just get it checked and diagnosed so you know what the real problem is.

My problem does go away after it warms up, my mate said it was my engine oil leaking in or some shit causing it to smoke but im pretty darn sure its not because then it would be "blue" white smoke or something like that. Its just plain white.... although previously it was pretty wild and it did go into my neighbours back yard... i even took it for a test drive down my road to warm it up, i looked behind to see the road to be compltely smoked hahaha with an old man staring at me walking his dog thinking my car was gna explode.

As for thicker oil, I'm not sure if that will help or not, i recently did a service with 10w-40 , i might jump to 10w- 50 since the car has been running for 220kkms now....

And for that rattling sound i guess ill just take it to the exhaust shop then... its pretty annoying now that i notice it there, especially since im such a rev head i hear it constantly now, sounds like stupid small pieces of rocks just jumping around having fun in the exhaust. Any good reccomendations as to where i should get it checked out at? I'm located in S.E Burbs, MELB.

PS: where roughly is the cat converter located?

Pretty much between the driver/passengers seat underneath the car. If your cars stock, you'll notice a heat shield. it'll look like that http://www.jshmotors.com/images/prod...-R-Cat-004.JPG

Just give it a light tap here and there and see if somethings rustling inside.

Ahh okay i know what that is, Im pretty new to this stuff, this teg is basically my first car. Planning to work on it and maybe do a engine swap later on...

FIrst i need to find a jack that can get under my car... its so ****ing low haha

Lol we do the same thing just drive it straight away, to get the smoke away. It is oil leaking in the chamber. I took it to the mechanic he said nothing you can do but to rebuild the engine or put thicker oil in there to fix it abit. But since your doin a conversion just put up with it for a while lol.
