Clear Smoke + Brown Liquid

[Jamie77]

Hey guys I was hoping someone might be able to help me over come a problem I have. I have a 1986 ae82 flatback corolla and at the moment its blowing clear smoke upon start up and leaking a light brown liquid from the end of the exaust tip and some times leaves a think build up of thick liquid after leaving the car running for awhile the smoke clears but the liquid still occours any thoughts? Some people seem to think its the head gasket but I'm not so sure my temp meter never makes its past a quater due to the thermostat being by past and fan always running thanks for reading guys please leave your thoughts.

Have a look in the radiator. Drain the oil into a clean container and inspect it. Sounds like your mixing water and oil somewhere.

due to the thermostat being by past and fan always running .

 

That sounds dodgy.. does it lose water at all?? How often do you top it up?

 

What littleredspirit said, or check for drops of water under the oil filler cap or the tappet cover before you drive away one morning. Its either losing water into the exhaust or the smoke is just condensation from combustion. It shouldn't occur when the motor is warmed up.

I'm not losing any fluid but I know it needs a oil change its in a blue slip zone at the moment It just sits here and I run it every now and again and your right when it warms up the skoke stops but that brown liquid is still there also when changing coolent and oil would it be a good idea touse a flush with these older cars?

[altezzaclub]

I'd say so- flush the oil to get rid of as much shit as you can. The old idea was a 50:50 mix of diesel and kero, you tossed in 4litres, started it up and let it idle for 10minutes. Now you can buy special flushing mixtures.

 

It wouldn't hurt to take the radiator out and flush it upside down with a garden hose. Bits of rubbish sit on top of the tubes and slowly block them.

Any way this is how it looks iv a major service to it myself spark plugs leads coolent etc but still to do oil... http://www.rollaclub.com/board/gallery/image/10394-20130502-130136/

Rusty water, and steam, caused by the hot exhaust gas condensing on the cooler exhaust pipe? is it oil and water, oil or just water?

[Jamie77]

Seems like just water bro but not 100% sure...

[Jamie77]

Just rusty water... is that a good thing? Lol

[Bowler]

well, the exhaust is usually mild steel, which will corrode over time. so a certain amount of corrosion by way of rust, is acceptable. so long as theres no evidence of cooling issues, or milky oil, then its quite probable, that the water vapour in the exhaust is condensing and being blown out...

Il probly still get it checked by a mechanic but you were a great help thanks alot.
