This might be a silly question, Paul, but are you sure it was blue smoke? Is it puffing the smoke all the time? If it only occurs when you first start up in the morning, are you sure it's not steam, which is grey but can look bluish in the right light? That is quite normal and should disappear fairly rapidly as the exhaust warms up. Yes Jim definitely Blue /Grey this time. It has had the white steam coming out on the colder mornings and some water spurting out the exhaust but again that soon clears and nothing shows coming out? |

 So Mrs P went to work Tuesday morning in the Rav and I noticed some Grey/Blue smoke come out the exhaust, bad news, it hadn't been started for a while and was expecting the battery to be flat but no it was fine, good news  So since then she's been going in the Yaris again, so I started the Rav up today and again Grey/Blue smoke came out the exhaust and a strong smell of petrol  Now looking on line it seems oil could be getting past the seals which harden, must be Navy seals  and that you can put a treatment in that softens the seals again makes the oil thicker, and stops the oil leak and Blue /Grey smoke??? So could this be happening because I have changed the oil and the MAF sensor. The oil did seem more thick as I mentioned when I did the oil change so perhaps the treatment was already in the engine when we bought it, do these treatments work if not is the engine on it's way out??? I'm not a mechanic, don't know what I'm talking about, but merely highlight a couple of items from the evidence given for possible consideration by those who are and do ...  Could the mixture simply be too rich on start-up? That's what I was thinking Philip as the MAF i changed wasn't a genuine Toyota part so could that be having an effect?? |

Paul , does the smoke smell of burning oil ? Not that I have noticed Jase just a strong whiff of petrol I got this afternoon. When I started it back up about twenty minutes later nothing came out, no smoke no smell of petrol. |

Decent trip would probably do it good Paul.

That is quite normal and should disappear fairly rapidly as the exhaust warms up. Yes Jim definitely Blue /Grey this time. It has had the white steam coming out on the colder mornings and some water spurting out the exhaust but again that soon clears and nothing shows coming out? 1. So blue/grey but only on start up? 2. When warm and you rev it, no smoke? 3. Is it using excessive oil? 4. Is mpg steady/normal? 5. Is the car running well? Like Philip, I am no mechanic but I've been around cars and bikes all my life and have learned a few things. Having owned six RAVs now I have definitely learned that they are extremely reliable and robust and they seldom develop problems out of the blue (especially the petrol VVTi). If the answers to the above five questions are yes, no, no, yes and yes I would guess that there isn't much wrong and just keep an eye on it. As Dave has suggested, a good run out probably would do it good. |

All points correct Jim so will see how we get on with the trip out I will video tomorrow mornings start up and if you are on WhatsApp I can send you the vid to look at? |

Paul our 4.2 does the same if it’s been stood for a while. The Mrs does less than 3K miles a year in it. At first I thought the same as you but as soon as it warms up it’s disappeared. The petrol smell is there occasionally too but only when it starts up after a long stand.
This is our 3rd petrol Rav and they all did it when it’s cold.

That's reassuring to know Ash :TU: This mornings start was just white smoke. I don't suppose we noticed so much with the Blue Rav as it was used daily, and our little jaunt down to Tewkesbury and back was fine as the Rav was better than Ol Blue we both thought :yes: I looked when Mrs P started it again and no smoke at all was seen so is just when it has been laid up for a while It seems?? |

If you knew the lengths the red arrows went to get it.......
I think I’ve already spent more time worrying about that problem than I would on my car at that age. It’s just something that happens. Oil seeps past valve guides and sticks to the cylinder walls and you burn it off on start up. Fully synthetic oil might do it more. Make sure the air filter is clean so it can breath freely and stop worrying.

Cheers Don :TU: I have used semi synthetic and the air filter was changed a few months back, so is it worth still changing the PCV valve as Bob suggests, and what about the emissions test on MOT day will it be picked up then?? |

Well the PCV valve has now arrived thanks Kingo so will attempt at having a go at fitting it, fingers crossed  |
