We bought a 2006 T180 - D-CAT. Last autumn, 80,000 miles on the clock. In march the car developed a fault and was diagnosed with leaking head gasket. The garage I bought it from had it repaired as it was under a warranty. Due to lock-down the garage couldn't finish the repair until this week. We collected the car and I followed my wife home. I noticed that occasionally the car emitted quite a bit of white smoke or steam. Especially under acceleration. Today I followed her again and the car seems a lot better but occasional spat out white smoke and possibly some water spray when under hard acceleration.
I have checked the coolant level, it is full and checked the oil. it is nice and clean. Is it possible that the head is still still blowing? Or maybe some residue is burning off after the repair. Or is this actually normal and we haven't noticed it before? I am aware that the D-CAT occasionally sprays fuel into the exhaust, what does this look like?
Thanks in advance
Mike

I remember seeing this on my 150 SR with the D-Cat system. was a concern until I sussed what was happening (as schm describes)

I know that diesel is injected directly into the exhaust, I assume that some of that extra diesel can spray out of the exhaust at times? |

I know that diesel is injected directly into the exhaust, I assume that some of that extra diesel can spray out of the exhaust at times? Possibly, but I'm more inclined to think it's the contents of the diesel particulate filter (DPF) being burned off, or a mixture of both. There are at least two methods of filter regeneration, which requires raising the exhaust temperature, to burn off the captured filter contents. 1.The RAV has the 5th injector method. 2.Toyota (and others) also use(d) the post injection method. Diesel is injected by the main injectors, slightly after the main combustion event. This also raises the exhaust temperature. This method has also been know to leave quantities of diesel in the engine oil, diluting it and actually raising the measured "engine oil level" over time, as well as changing the lubrication properties. Another good reason for frequent oil changes. |

It' been happening to me since day one (almost 13years). There are many many posts about this matter.
Further than it's a little embarrassing(white smoke) does no harm. Mine stopped smoking once changed the four injectors at 170 thousand miles . If you find something please keep us posted . |

I wouldn’t lose a minute’s sleep over that. The early models were quite adept at red arrows impressions.

hi guys,
I've got the same issue, thick white smoke cloud when accelerating usually in 2nd and 3rd gear just for few sec then it goes away and its randomly, not all the time. I also experienced that on driving slowly in the first gear in traffic.
The coolant has the same level and it doesnt seem any in the oil check. What do you think it would cause that? Injectors or head gasket? I literally can't say what it smells like, sorry, im tempting to say fuel?
So if that would be the injectors, is this job very costly? how about a head gasket job?
thank you so much

:welcome: to the club tino :TU:
Have you read the previous posts in this thread? Consensus seems to be to not worry about it.
Mikis did change the injectors at 170K.....

Try changing the oil every 5000 miles or less. |

Can you blank off the 5th injector

Can you blank off the 5th injector I wouldn’t do that. Nor would I blank the EGR….. I’m surprised at how many of the cars with the 2AD engine are still suffering the same old woes they were ten years ago. I go on the RAV4 owners page on FB and it’s an average of 1 car failing every week. Of course FB is full of idiots with ridiculous ideas but some are rightly being advised that the engine repair on the older cars is uneconomical. Last week there were two owners who put up video clips of their expansion tanks spewing coolant out of the spout. |
