Hi I have a 57plate 2.2d milage 87000 and was going threw some water. Today they was black water round the header tank. & Top it up started up & the water was pouring out of the over flow.
Thanks

Hi I have a 57plate 2.2d milage 87000 and was going threw some water. Today they was black water round the header tank. & Top it up started up & the water was pouring out of the over flow. Thanks Looks very likely it’s the old head gasket problem which has afflicted the 2AD series engine from 2006 up till 2013 when the 4.4 cars were introduced. Im on the Facebook RAV4 owners page and see on average 1 car per week with the old problems. Some dismiss it as just a simple head gasket going and think/ insist just changing the gasket is a solution, of course it’s not that simple. Crazy really that some cars never have a single moments problems and also that we’re still seeing failures 10 or 12 years after the Toyota good will warranty stopped. I tried at first to advise 2.2 owners to use quality fuels and low ash oil but FB is a jungle of mongrels who just refuse to accept a little friendly advice. I don’t bother anymore … Sorry Del it’s not good news …. |

The 'original' problem affected RAV4s with the 2AD engine built between Jul 2005 and Dec 2008 so a 2007 is certainly within that range. The key symptoms were: - Oil consumption worse than 0.5 litre per 621 miles (1,000 km)
- Overheating & Head Gasket failure due to carbon deposits on the pistons
Do you also have excessive oil consumption?

All of the Mk 3 or as we call them 4.3 cars were affected, Jamie on this forum ( Rambler ) was the most recent I can think of has the head gasket go on his low mileage 2012 car. The dealer took the car back if I remember correctly and refunded his money. Lots of later 4.3s have gone and are still going at quite some rate. forum.rav4driversclub.com/thread/69/charliefarlies-guide-diesel-series-engineIt’s both sad and unfortunate that folk are copping for big bills or having to scrap thirt cars. Those of us who were in the thick of this subject I doubt never thought it would still be going on 10 years after the first complaints. Honestly join the FB page and have a look. |

Not using any oil. What else do I need to do or change when am doing head gasket? Thanks Using oil is one symptom but not always present. Heavy fuel consumption is another again not always present. When Toyota rebuilt the engines or latterly replaced some had brand new cylinder heads, new injectors, inlet manifolds etc but again you got what you got so you may have had all of the above or none of them. So no one can say what will be re usable or not. I understand that these are complex and expensive engines to repair. If I remember correctly Jamie’s 2012 car was deemed an uneconomical repair which is why the dealer took it back and refunded him. Jamie will hopefully confirm as I’m working from memory. Del if you read the info in the link all should become apparent. Unfortunately I have no good news . It was always going to happen that once Toyotas generous good will warranty expired owners would get caught out. Whatever you do if you decide to repair you need someone who intimately understands the whole issue as folk are now just replacing the head gaskets and they’re going again. You could do worse than join the FB page where this subject comes up weekly. |

Does diesel burn if, by accident, the car brake fails and it rolls into a bonfire locals made on waste ground as climate demonstration?
Seriously, I was surprised my 2.2 auto petrol needed the ECU reprogrammed at 104,000 miles.
Equally saddened that the 2006 petrol auto low mileage 4 door needed both sides sills replaced....so bad that the car also needed the underside de-rusted at a cost of £1,000. (Most of these 4.3s are being scrapped). The quality seems to have dropped off since the 4.1, which did have rust problems in the UK....but never tackled properly - example being the fuel filler pipe.

So, the question is, what should our new friend Crofter do now? (Note that this is not the original Crofter)
If the engine has succumbed to the inherent weakness of the 2AD of that period it would need a new 3/4 engine / competent engine rebuild - and that would almost certainly cost more than the car is worth. So probably best to write the car off as beyond economic repair?
But there exists the possibility, albeit perhaps a rather small one, that this is just a failure of the head gasket. In which case it could be competently repaired. As I understand from lurking and reading around the head can be skimmed if necessary but the repair must then use an appropriately thicker head gasket to maintain clearance between the valves and pistons! Such gaskets are available. There is no guarantee that such a repair will last ...
I'm in absolutely no position to advise which of these two options is more appropriate in this case ...

Such gaskets are available. There is no guarantee that such a repair will last ... I'm in absolutely no position to advise which of these two options is more appropriate in this case ... Bear in mind it’s around 10 or more years since I wrote the guide I linked to above. It was originally written when a lot of us were members on the other forum. So I may not get things 100% correct. Firstly it’s extremely likely to be the old issues that have never gone away, No one can say 100% I guess until they have the engine apart. If it is the common issue it’s fair to say it’s an uneconomical repair. Just a simple head gasket no problem but Toyota didn’t supply and fit re manufactured engines if a head gasket would cure it. My understanding is the head cannot be skimmed. I’m not 100% sure because there is much conflicting info out there. Even if it can the rest of the engine would likely cause another failure. That’s based on the long arduous history regarding this subject. Very sad to say there are no positive answers. It was always going happen as there is no rhyme or reason as to when failures would or could occur. I can’t remember when the good will warranty expired but still these occurrences appear far to often. I thought crofter was an old member from TOC and was also on here some time back. 👍👍 |

Philip, I've never managed to find out what "the inherent weakness of the 2AD of that period" is. Do you, or perhaps Charlie, have any details of what the weakness is? I'm running one of these engines and have done for 105k miles. I believe that Davrav has done a lot more miles than this without problem. Mine has had it's oil changed ( 10w - 30 ) twice a year since new ( I think that the advice came from Anchorman originally ).

145K and change at the moment..........
Still using Archoil 6900-DMax. Put a dose in this morning before a fill up as it happens. Does seem to increase mpg by a couple of miles/gallon and engine is considerably quieter.

Chris there is a link to the thread I wrote many years back that will give you the nuts and bolts …. The actual cause according to one of the technicians that set up a Toyota specialist garage in Worcester was the extremely restrictive EGR valve….. Im no longer a fan of that technician because he did a bad turn to one of our esteemed members and then rubbed me up the wrong way but the fella really knows his stuff as does his business partner as they were both master technicians at Worcester Toyota. The one thing owners can do to help prevent the build up of carbon and other nasties is to use quality diesel and as David mentions above an additive like the Archoil David uses. Plus it’s a good idea to use the correct Low ash or low SAPS oil. As I mentioned above there is no rhyme or reason why some engines go for big mileages and others pop early. It’s a fair deduction to make that says engines in cars that do short trips get fed supermarket pish ( As Kev calls it ) and get filled with cheap oil are at the most risk. |

i have a 4.3.5 2011 model i thought the problems were in the previous 4.3. am i wrong All and any diesel 2.2 from the introduction of the third generation ( we call the 4.3 ) in 2006 up till the introduction of the 4th generation ( 4.4 ) are at risk. The T180 and SR180 were the most prone probably because they burnt more diesel equalling more soot and carbon blocking the EGR valve the inlet manifold and the cylinder head. Can anyone remember the situation with Jamie’s car ? I’m sure it was a 2012 and had from memory 30+K miles ?? It was roughly a couple of years ago ……. |
