The following is tendered as an alternative suggestion and is not going to be applicable for most owners.
It is more about balancing price and quality for your specific driving conditions.
Over the past 6 years or so, I have been using both genuine and aftermarket oil filter cartridges for my 2GR-FE engine. There is a difference in the oil filter cartridges as to the quality and amount of the element. This is what you are paying for when you buy genuine or quality better than OEM vs cheaper [supposedly] OEM standard ones. In a different thread titled Genuine vs Fake parts, there is a YouTube video demonstrating the better/higher effectiveness of the genuine Toyota filter
My engine is full of oil sludge from the time that I bought it with a dubious service history. Furthermore, as I have posted many times, most of my driving is short distance urban driving approx. 15 minutes so ideal conditions for the formation of oil sludge. Therefore, I do an overkill oil change procedure [in a separate thread] and do it very regularly. My oil change interval is approx. 3000 kms or less depending upon the oil colour. I am DIY and somewhat "price sensitive". Therefore I am not going to use the absolutely best quality oil and oil filters. Very different matter if my engine oil was still a nice amber colour after 5000 kms of mostly highway driving. Then it would be worthwhile to be using the higher quality oil filters and a higher quality engine oil to support an extended oil change interval of either 6 months or 8000 kms.
On a visual comparison basis for the number of pleats in the element and personal experience, I have got acceptable results from the OEMASSIVE brand Made in China. I am basing these "results" upon the amount of sludge particles captured in the element. This brand also recommends that the cartridge be changed by 5000 kms. Guess that you can draw your own conclusions, so presumably not suited for a longer interval.
Planning upon being a longer term owner of my Toyota and DIY for many years to come, I have placed a bulk order on eBay. 48 filters for $105 was the best deal that I had located. Certainly better than a previous purchase of 6 for $22.
Quantity can have a quality of its own in specific circumstances. Still considering whether to change the oil filter cartridge about mid-way in a planned oil change interval to keep the engine oil cleaner. In the meantime, I will be keeping my genuine oil filter cartridges in reserve until the engine becomes relatively sludge free.
I was very impressed with how clean the cylinder head and valve cover was, particularly when compared to what my engine was like. I thought that it was testament to the frequency and quality of the previous oil changes so not exactly indicative of an indifferent neglectful owner. If the cylinder head and valve cover had heaps of oil sludge then I would not have been so surprised about the engine teardown.
Unfortunately not enough background information/history to confirm whether the engine overheated before the change of water pump or shortly afterwards.
Main learning from this video is the importance of regular fluid level checks to top up as required and detect any leaks. Definitely cheaper to fix/monitor any coolant leaks before the engine overheats. I am a bit pedantic or OCD so I usually check every week or fortnight as I have an "elderly" 2006 vehicle. Always monitoring the engine oil and coolant level in the overflow bottle. No dipstick on the transmission but I am continuously monitoring the smoothness of the gear changes.
I have a zze122 corolla that had a new clutch fitted and it has now started pouring power steering oil out of the power steering reservoir it doesn't appear to have a air lock as there aren't any bubbles in the oil and sometimes the power steering is not working properly any help would be appreciated cheers dennis
Big disclaimer that I am not a Corolla owner with no direct experience. I did go and view YouTube videos but only saw ones relating to USA and the hub assemblies looked to be different. Also they were having to press on the hub assembly.
Finally went to the Amayama parts website and located a diagram for the front hub assembly of the Corolla ZRE152R.
Certainly indicates that it is a bolt on/off part.
Best way to confirm the relevance of this information/diagram is to actually jack up the vehicle and remove a front wheel.
just like to give you a big Thank You for your perseverance in taking the time and effort to stand up for your consumer rights.
Certainly hope that this eases the struggle for other affected owners and Toyota Australia now does "the right thing". In hindsight, they should have agreed to a confidential settlement before getting to an arbitration and ruling. Their "gamble" of disregarding Australian Consumer Law has not worked and it is now time to pay in full for their bad behavior to all affected Toyota owners. There was a previous post that included John Cadogan's recent YouTube video on this peeling paint issue, so very much a hot topic in the public arena for John to do a video. Hopefully, Toyota Australia now realises that the stage is now set for a successful class action especially from those owners that have had their claims "unrightly" declined.
As Tony mentioned in a previous post, it most likely could be the paint primer supplier rather than the manufacturing process. It remains Toyota's responsibility.
Thank you Anthony.
Don't give up on your consumer rights to have a vehicle that is a durable product. Toyota Australia should hold their head in shame for how they are treating their customers. They know of the quality problems with paint codes 040 & 070, yet choose to fob their once loyal customers off.
Thank you Tony.
Work will commence in first week of October 2022. I have been informed 20 days will be required for the repair process to be completed. Toyota Australia has come to the party and will be accepting the cost with the local dealer carrying out the work using a subsidiary Auto repair business. All work will carry the usual warranty while also using OE hardware.
The dealership has kindly offered a loan vehicle during the repair period.
Good luck to everyone who is affected by this paint issue. My recommendation is that you all do your homework and gather the data and facts that will build a case. Then proceed to your state small claims tribunal. Another way would be to all band together for a class action towards Toyota Australia.
Hopefully what I have achieved will help you all.
