White Smoke from yaris D-4D - Toyota Yaris Forums

mba788 · 07-30-2009, 04:46 AM

Hi I am new to this forum,
I have a 2004 Yaris D-4D with 109k on the clock. There is oil in the exhaust which is causing white smoke. There is no oil or water leak from anywhere within the car. I took it to one mechanic he said it could be piston ring. Any ideas anyone? The car runs perfectly.
Thankyou for your help
Billy

Have you ever had any overheating issue? If not it can be caused by the piston ring..

Tamago · 07-30-2009, 07:20 AM

white smoke is caused by water.

you have a blown head gasket. check your oil, see if there's any creamy substance under the oil cap itself

Yaris Hilton · 07-30-2009, 09:55 AM

Oil smoke is bluish white. The two usual suspects for that are worn rings or valve seals.

A blown head gasket will pressurize the cooling system, pushing coolant out the overflow and making bubbles in the tank.

Are we talking a continuous cloud of white smoke or just a hint of blueish smoke on startup and deceleration? If its the white smoke when you change the head gasket dont forget to change the oil and filter before you start the car because your oil will be contaminated with coolant/anti freeze,not good for engine lubrication,and of course the engine cooling system will have to be flushed and refilled with fresh 50/50 coolant.

yeah, that is true, i blew a head gasket
in my civic, get it checked out ASAP...

Is it white smoke or steam from the exhaust? Pull the spark plugs. If any of them are fouled with black carbon and oil then that cylinder has bad rings or valve seals.

mba788 · 08-22-2009, 01:31 PM

It's not the head gasket there is no white emulsion under oil cap. There is back pressure from the oil cap. When I change gears there is white smoke coming, n when I accelerate heavy with high revs theres plenty of white smoke continuous at times, but sometimes it's perfect

thanks

silver_echo · 08-22-2009, 06:00 PM

do both a compression and a leak-down test... that smoking issue says problem to me... once you know which cylinder is not working for pressure, find access to a boroscope to look at your pistons and valves... this way you can see if it is the rings or valves without tearing the motor down... only reason that i recommend doing it this way is because if you take it to a shop and they tear it down to check it, you are pretty much committed to the repair because of the fact that they already have it torn down...

Yaris Hilton · 08-22-2009, 09:33 PM

I kinda overlooked that this is a diesel. White smoke will come from a diesel when the fuel doesn't ignite in a cylinder. Often that is the result of a compression loss, like a valve that's not sealing properly. You should be able to feel and hear roughness in the engine if there's misfiring, and that white smoke has a strong kerosene-like smell from unburned fuel.

silver_echo · 08-23-2009, 12:06 AM

well i missed the diesel part too... but i guess the compression test would help on diesel as well...

severous01 · 08-24-2009, 09:19 AM

well if you wanna do i t yourself it's cheap and easy.

get a compression tester from autozone. 20 bux for the cheapo, and about 50 for the stainless lined one that's about snap-on quality. any way, pull all plugs and disable injectors. install compression tester, start engine and mark the first puff and the 4th puff. should be about 40+ and 100+ and all 4 cylinders should be close to equal...w/in 10%.

ok....i missed the diesel part. but you still have diesel compression testers out there u just gotta remove the injector, not the spark plug.......cuz there are no plugs.

Yaris Hilton · 08-24-2009, 09:39 AM

It's a Diesel. No spark plugs, It'll take a special gauge to check compression.

ibizagti · 08-24-2009, 09:40 AM

The problem, probably, is the turbo.

I have heard more problems with turbo in 1.4 D4D engine.

Regards.

Yaris Hilton · 08-24-2009, 10:23 AM

Hmmm, leaky oil seal in the turbo is a possibility.

I'm thinking this might ought to go to a good Diesel mechanic.

06silveryaris · 08-24-2009, 12:41 PM

if the exhaust is oily and compeshion is good my guess would be the turbo

jambo101 · 08-24-2009, 03:41 PM

The only fluid that will produce a cloud of white smoke from your car is water in the combustion chamber and the only way it can get there is a broken head gasket or a cracked head unit.

Yaris Hilton · 08-24-2009, 05:33 PM

That's simply not so about water being the only thing that makes white smoke.
