Ruh Roh....puffs of white smoke, and its not the chronic.
So I was a red light today coming home from work and I was looking in my rear-view mirror, making sure the blond milf on the cell phone didn't ram her Escalade emblem up my ass, I noticed white smoke trickling away from the rear of my car. A little shocked, i revved the engine and nothing happened. Thinking it was the jalopy next to me, I moved on.
At the next red light (and clear of the jalopy and the milf), I looked up and saw puffs of white again! Argh. Once again, I revved the engine and nothing happened. For the next few miles home, I had my eyes glued to the rear-view and still no smoke. Once I got home, I let the car cool down a little and did some revs in the driveway, only once did a little white puff of cloud came out and I couldn't repeat it after trying for almost 10 minutes. I have no clue what it could be, anyone? Engine runs excellent, no overheating, normal oil pressure, normal a/f. The only thing I could think of is that my catalytic converter has seen it's last days due to the AWFUL smell it is emmiting and the constant rattling. Could that be the culprit?? Thanks. |
White smoke is water/coolant.
|
white smoke = coooooolant burning normally and that normally leads to a head gasket.... *Shrug*
Black = Rich Blue = Oil White = Coolant thats the rule of thumb if i remember right |
I believe so.
|
I've never seen or experienced a leaky head gasket before, are you guys SURE it couldn't be anything else? Vacuum lines? Little gnomes smoking crack?
I researched it some on m.net and someone mentioned a liquid head gasket/block sealer. So I drove to the Vatozone with my loud pedal to the floor to buy some and still no smoke!! At least I have the sealer now, so I'll start with that on my next day off. |
i'm not sure what your exhaust setup looks like, but on mine, after a good rain, if my car is parked in such a way where rain can get into the exhaust, i'll get a bit of white smoke pouring out for a bit until it burns the moisture out.
That could just be a south Louisiana thing. EDIT: I see you are from SoCal, so let me explain the above. Rain is moisture that falls in in the form of droplets from the sky. Perhaps you've seen the phenomena on TV. |
I wouldn't dump any "sealer" into your cooling system until you're more confident what is going on. A head gasket rupture usually has other symptoms as well, like milky coolant in the rad., watery oil, losing coolant, etc.
It could easily be condensation in the exhaust burning off. |
just watch your water level. Its not like a head gasket is difficult to swap out, it just takes some time.
|
It could also be a leaky turbo seal. I know I'm in that boat right now.. My engine leaks down less than 8% on all cylinders and it smokes sometimes.. in my case, it's the turbo on there.. shaft has more play than House Party on DVD.

diff leaking on exhaust....parking brake left on?
|
OK guys, went out for a closer look today. Here's what I found:
1)Let the car idle for about 5 minutes and white/greyish smoke started blowing out of tailpipe slowly. It comes and go. I went down and smelled it and it smelled like burnt oil mixed in with normal exhaust smell. 2) The Bailey BOV is covered with a thin coat of oil, as well as the stock air pipe right below it. 3) Pulled spark plugs (colder plugs from FAQs) and numbers 4 and 1 were significantly darker then numbers 2 and 3. Not sure if that means anything, just an observation. 4) Coolant looks like coolant. Ideas? Thanks guys. Nester, does the turbo seal leak at boost or at idle also? |
most times if your engine bay is covered in oil it's leaking from headgasket or the valve cover seals.
|
sounds like a blowed the fuck up turbo.. ;)
|
Valve cover gasket is new, the oil is just coating a portion of the BOV, and INSIDE the bov and directly underneath it. I'll try to get pics if it happens again. I wiped it off and went for another drive....
Welps, right after that I typed the above update, I capped off the breather vent on valve cover with a little air filter I have laying around and blocked off the nipple on the greddy u-tube with a rubber plug, went for a drive. No smoke. It's idling right now, but so far, no smoke....... Nester, you meany. :P |
when you fist turn ze car on is there a white puff? Have someone stand behind ze car when you turn it on. If any white puffs say Headgasket ze bye bye.
